Our Networking Products

     We are a designer and supplier of network infrastructure products that enhance, manage and support the transmission of data from computer servers to storage systems and from computer servers to other servers. Computing and storage systems handle large volumes of data and require network infrastructure products that enable fast transfer of data and efficient sharing of resources.

     Our products are used in connection with three distinct types of networks: Storage Networks, High Performance Computing, or HPC, Networks, and Converged Networks. Storage Networks are used to provide critical data across widely-distributed environments and primarily use Fibre Channel technology. HPC Networks allow the utilization of advanced parallel processing over multiple servers and typically are used for applications where very large amounts of data must be processed quickly and efficiently. The HPC Network products that we sell use InfiniBand® technology. Converged Networks are designed to address the evolving data center by consolidating and unifying various classes of connectivity and network traffic. For example, Fibre Channel over Ethernet, or FCoE, uses one common Ethernet network for both Fibre Channel storage and Ethernet data transmission, thus combining the benefits of Fibre Channel technology with the pervasiveness of Ethernet networks, which is what most local area networks utilize.

     Our products are sold worldwide, primarily to original equipment manufacturers, or OEMs, and distributors. Our customers rely on our various networking infrastructure products to deliver solutions to information technology professionals in virtually every business sector. Our products are found primarily in server, workstation and storage subsystem solutions that are used by small, medium and large enterprises with critical business data requirements. The business applications that drive requirements for our networking infrastructure products include:

	•		General business information technology requirements;
	•		Data warehousing, data mining and online transaction processing;
	•		Media-rich environments such as film and video, broadcast, medical imaging, computer-aided design, or CAD, and computer-aided manufacturing, or CAM;
	•		Server clustering, high-speed backup and data replication; and
	•		Research and scientific applications.

     Our products generally include adapters, switches and application-specific integrated circuits, or ASICs. Adapters physically reside in a server and provide for connectivity from the server to storage, HPC and converged networks. Switches manage the transmission and routing of data from servers to storage devices or from servers to servers. The ASICs that we sell are protocol controller chips that are embedded within a server or storage device.

     We classify our products into three broad categories: Host Products, Network Products and Silicon Products. Host Products consist of Fibre Channel and Internet Small Computer Systems Interface, or iSCSI, host bus adapters; InfiniBand host channel adapters; Fibre Channel over Ethernet, or FCoE, converged network adapters, or CNAs; and Intelligent Ethernet adapters, or IEAs. Network Products consist of Fibre Channel switches, including stackable edge switches, bladed switches, virtualized pass-through modules, and high-port count modular-chassis switches; InfiniBand switches, including high-end multi-protocol directors, edge and bladed switches; Enhanced Ethernet pass-through modules; and storage routers for bridging Fibre Channel, FCoE and iSCSI networks. Silicon Products consist of Fibre Channel controllers, iSCSI controllers, converged network controllers and Ethernet controllers.

     Host Products accounted for 72%, 70% and 73% of our net revenues for fiscal 2010, 2009 and 2008, respectively. Network Products accounted for 18%, 18% and 17% of our net revenues for fiscal 2010, 2009 and 2008, respectively.

     Storage Networking

     Our ability to address the market for Storage Networks stems from our broad product line based on Fibre Channel and iSCSI technologies. Fibre Channel is currently the dominant technology for enterprise storage networking, while iSCSI is a lower cost alternative primarily used by small and medium sized businesses.

     We provide Fibre Channel and iSCSI adapters for servers as well as mezzanine adapters for bladed servers, which connect host computer servers to storage networks. We also provide a broad line of Fibre Channel switches, including stackable edge switches, bladed switches, virtual pass-through modules, and high-port count modular-chassis switches. A unique feature of our edge and modular-chassis switch is its stackability. Stackable switches use dedicated high-speed stacking ports as inter-switch links, or ISLs, allowing for simplified future expansion and scalability, reduction in necessary device ports, lower upfront and future expenses, and reduced management costs and complexities.

     In addition, we provide intelligent storage routers for bridging Fibre Channel, FCoE and iSCSI networks. Our intelligent storage routers provide a cost-effective way for iSCSI-based servers to access storage devices already deployed on a Fibre Channel storage network.

     HPC Networking

     Our High Performance Computing Networking products are based on InfiniBand technology. InfiniBand is an industry-standard specification used to connect servers, communications infrastructure equipment, storage and embedded systems, and is used primarily within high performance computing environments where its capability to quickly and efficiently process data-intense calculations is crucial. Our ability to successfully address the requirements of server vendors targeting high performance computing environments is enhanced by our experience and success addressing the server-to-storage connectivity demands of these same customers. These products provide high performance solutions for cluster and grid computing networks. We offer a comprehensive, end-to-end portfolio of InfiniBand networking products for HPC Networking including quad data rate, or QDR, host channel adapters, QDR multi-protocol directors, edge switches and bladed switches, as well as software tools to install, operate and maintain high performance networks.

     Our QDR InfiniBand switches range from fixed configuration to fully configurable, modular director class switches. The modularly designed QLogic directors can scale from as few as 18 ports to the maximum of 864 ports, giving customers the flexibility they demand.

     Converged Networking

     Our Enhanced Ethernet based portfolio included in our Converged Networking products consists of CNAs and IEAs. CNAs are a new class of networking products that support the emerging Fibre Channel over Ethernet technology. FCoE is a converged networking technology that provides a unified storage and data network over Enhanced Ethernet, while preserving the investment in existing Fibre Channel infrastructure and storage. Our CNAs enable true network convergence by combining the benefits of Fibre Channel technology with the pervasiveness of Ethernet networks and leverage our core technology and expertise, including our mature Fibre Channel driver stack. Based on QLogic’s advanced Network Plus Architecture, our CNAs are designed for next-generation, virtualized and unified data centers with powerful multi-processor, multi-core servers and are available in multiple adapter form factors, including standard and mezzanine cards. Although we are shipping FCoE products, as with most emerging technologies, it is expected that the market for FCoE will take a number of years to fully develop and mature. Our IEAs are designed for various applications such as virtualization, cluster computing, internet protocol content delivery systems, grid computing, database clustering, network attached storage, and storage and backup servers.

     The acquisition of NetXen, Inc. in April 2009 expanded our product portfolio to include Ethernet networking products that are complementary to our existing products. The acquisition also expanded our expertise to better address a wider range of emerging customer requirements for converged networks and enhanced our ability to compete for future converged networking design wins.

Customers

     Our products are incorporated in solutions from a number of storage system and computer system OEM customers, including Cisco Systems, Inc., Dell Inc., EMC Corporation, Hewlett-Packard Company, International Business Machines Corporation, NetApp, Inc., Oracle Corporation and many others. A small number of these customers account for a substantial portion of our net revenues, and we expect that a small number of customers will continue to represent a substantial portion of our net revenues for the foreseeable future. Our top ten customers accounted for 86%, 84% and 85% of net revenues during fiscal 2010, 2009 and 2008, respectively.

     A summary of our customers, including their manufacturing subcontractors, that represent 10% or more of our net revenues is as follows:

		2010				2009				2008
Hewlett-Packard			24	%			21	%			20	%
IBM			20	%			18	%			16	%
Sun Microsystems (acquired by Oracle in fiscal 2010)			*				11	%			11	%

     We believe that our relationships with our customers are good. However, we believe our major customers continually evaluate whether or not to purchase products from alternative or additional sources. Additionally, customers’ economic and market conditions frequently change. Accordingly, there can be no assurance that a major customer will not reduce, delay or eliminate its purchases from us. Any such reduction, delay or loss of purchases could have a material adverse effect on our business, financial condition or results of operations.

     Some of our OEM customers experience seasonality and uneven sales patterns in their businesses. The seasonality is primarily due to the closing of a disproportionate percentage of sales transactions in the last month, weeks and days of each quarter and spikes in sales during the fourth quarter of each calendar year. Although we do not consider our business to be highly seasonal, we believe that seasonality has and may impact our business. To the extent that we experience seasonality in our business, it would most likely have a negative impact on the sequential growth rate of our net revenues during the fourth quarter of our fiscal year.

     International revenues accounted for 54%, 52% and 49% of our net revenues for fiscal 2010, 2009 and 2008, respectively. For additional information on our international sales and operations, see Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in Part II, Item 7 of this report.

Sales and Marketing

     Our products are marketed and sold primarily to OEMs by our internal sales team supported by field sales and systems engineering personnel. In addition, we sell our products through a network of regional and international distributors.

     In domestic and in certain international markets, we maintain both a sales force to serve our OEM customers and distributors that are focused on medium-sized and emerging accounts. We maintain a focused business development and outbound marketing organization to assist, train and equip the sales organizations of our OEM customers and their respective reseller organizations and partners. We maintain sales offices in the United States and various international locations. For information regarding revenue by geographic area, see Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in Part II, Item 7 of this report.

     We work with our storage system and computer system OEM customers during their design cycles. We support these customers with pre-sales system design support and services, as well as training classes and seminars conducted both in the field and from our worldwide offices.

     Our sales efforts are focused on establishing and developing long-term relationships with our OEM customers. The sales cycle typically begins with the identification of an OEM’s requirement that could be potentially fulfilled with an existing QLogic product or a product based on a new technology. The cycle continues with technical and sales collaboration with the OEM and, if successful,

leads to one of our product designs being selected as a component in a potential customer’s storage system or computer system. We then work closely with the customer to integrate our products with the customer’s current and next generation products or platforms. This cycle, from opportunity identification to initial production shipment, typically ranges from six to twenty-four months.

     In addition to sales and marketing efforts, we actively participate with industry organizations relating to the development and acceptance of industry standards. We collaborate with peer companies through open standards bodies, cooperative testing and certifications. To ensure and promote multi-vendor interoperation, we maintain interoperability certification programs and testing laboratories.

Engineering and Development

     Our industry is subject to rapid and regular technological change. Our ability to compete depends upon our ability to continually design, develop and introduce new products that take advantage of market opportunities and address emerging standards. Our strategy is to leverage our substantial base of architectural and systems expertise to address a broad range of input/output storage and server networking solutions.

     We are engaged in the design and development of application-specific integrated circuits, or ASICs, adapters and switches based on one or more of Fibre Channel, iSCSI, FCoE and Ethernet technologies. We also design and develop ASICs, adapters and switches based on InfiniBand technology for HPC environments; and storage routers for bridging Fibre Channel, FCoE and iSCSI networks.

     We continue to invest in engineering and development to expand our capabilities to address the emerging technologies in the rapid evolution of storage, HPC and converged networks. During fiscal 2010, 2009 and 2008, we incurred engineering and development expenses of $136.8 million, $133.3 million and $134.7 million, respectively.

Backlog

     A substantial portion of our sales with OEM customers are transacted through hub arrangements whereby our products are purchased on a just-in-time basis and fulfilled from warehouse facilities, or hubs, in proximity to the facilities of our customers or their contract manufacturers. Our sales are made primarily pursuant to purchase orders, including blanket purchase orders for hub arrangements. Because of the hub arrangements with our customers and industry practice that allows customers to cancel or change orders with limited advance notice, we believe that backlog at any particular date is not a reliable indicator of our future revenue levels and is not material to understanding our business.

Competition

     The markets for networking infrastructure components are highly competitive and characterized by short product life cycles, price erosion, rapidly changing technology, frequent product performance improvements and evolving industry standards. We believe the principal competitive factors in our industry include:

•

time-to-market;

•

features and functionality;

•

product quality, reliability and performance;

•

price;

•

new product innovation;

•

customer relationships;

•

design capabilities;

•

customer service and technical support; and

•

interoperability of components in storage, HPC and converged networks.

     While we expect competition to continue to increase and evolve, we believe that we compete effectively with respect to each of these factors.

     Due to the diversity of products required in the storage, HPC and converged networking infrastructure, we compete with many companies. In the traditional enterprise storage Fibre Channel adapter market, our primary competitor is Emulex Corporation, with Brocade Communications Systems, Inc. also participating. In the iSCSI adapter market, our primary competitor is Broadcom Corporation and we also compete indirectly with companies offering software initiator solutions. In the FCoE adapter market, we compete with Emulex Corporation, and recent entry, Brocade Communications Systems, Inc. and we also compete with Ethernet adapter suppliers Broadcom Corporation and Intel Corporation. In the Intelligent Ethernet adapter market, we compete with Intel Corporation, Broadcom Corporation and Emulex Corporation. In the Fibre Channel switch and storage router markets, we compete primarily with Brocade Communications Systems, Inc. and Cisco Systems, Inc. In the InfiniBand adapter and switch markets, we compete primarily with Mellanox Technologies, Ltd. and Voltaire Ltd.

Manufacturing

     We use outside suppliers and foundries to manufacture our products. This approach allows us to avoid the high costs of owning, operating, maintaining and upgrading wafer fabrication and assembly facilities. As a result, we focus our resources on product design and development, quality assurance, sales and marketing, and supply chain management. Prior to the sale of our products, final tests are performed to ensure quality. Product test, customer-specific configuration and product localization are completed by third-party service providers or by us. We also provide fabrication process reliability tests and conduct failure analysis to confirm the integrity of our quality assurance procedures.

     Our semiconductors are currently manufactured by a number of foundries. Our major semiconductor suppliers are LSI Corporation, International Business Machines Corporation and Taiwan Semiconductor Manufacturing Company Limited. Most of the ASICs used in our products are manufactured using 180, 130, 90 or 65 nanometer process technology. In addition, we continually evaluate smaller geometries. In the past, we have experienced some difficulties in shifting to smaller geometry process technologies or new manufacturing processes, which resulted in reduced manufacturing yields, delays in product deliveries and increased expenses. We may face similar difficulties, delays and expenses as we continue to transition our products to smaller geometry processes.

     We depend on foundries to allocate a portion of their capacity sufficient to meet our needs and to produce products of acceptable quality and with satisfactory manufacturing yields in a timely manner. These foundries fabricate products for other companies and, in certain cases, manufacture products of their own design. We do not have long-term supply agreements with any of these foundries; we purchase both wafers and finished chips on a purchase order basis. Therefore, the foundries generally are not obligated to supply products to us for any specific period, in any specific quantity or at any specific price, except as may be provided in a particular purchase order. We work with our existing foundries, and intend to qualify new foundries, as needed, to obtain additional manufacturing capacity. However, there can be no assurance that we will be able to maintain our current foundry relationships or obtain additional capacity.

     We currently purchase our semiconductor products from foundries either in finished or wafer form. We use subcontractors to assemble our semiconductor products purchased in wafer form. In the assembly process for our semiconductor products, the silicon wafers are separated into individual die, which are then assembled into packages and tested.

     For our adapter, switch and other products, we use third-party contract manufacturers for material procurement, assembly, test and inspection in a turnkey model, prior to shipment to our customers. These contract manufacturers are located outside the United States. To the extent that we rely on these contract manufacturers, we are not able to directly control product delivery schedules and quality assurance. The loss of one of our major contract manufacturers could significantly impact our ability to produce products for an indefinite period of time. Qualifying a new contract manufacturer and commencing volume production is a lengthy and expensive process. While we believe that our relationships with our contract manufacturers are good, if we are required to change a contract manufacturer or if a contract manufacturer experiences delays, disruptions, capacity constraints, component part shortages or quality control problems in its manufacturing operations, shipment of our products to our customers could be delayed, resulting in loss or postponement of revenue and potential harm to our competitive position and relationships with customers.

     Certain key components used in the manufacture of our products are purchased from single or limited sources. ASICs are purchased from single sources and microprocessors, certain connectors, logic chips, power supplies and programmable logic devices are purchased from limited sources. If one of these suppliers experiences an interruption in its ability to supply our needs, or chooses to sever their relationship with us, we may be unable to produce certain of our products until alternative suppliers are identified and qualified.

     Many of the component parts used in our adapter, switch and other products are standard off-the-shelf items, which are, or can be, obtained from more than one source. We select suppliers on the basis of technology, manufacturing capacity, financial viability, quality and cost. Our reliance on third-party manufacturers involves risks, including possible limitations on availability of products due to market abnormalities, geopolitical instability, unavailability of or delays in obtaining access to certain product technologies, and the absence of complete control over delivery schedules, manufacturing yields and total production costs. In addition, the global economic weakness and uncertainty could adversely affect our supplier base and increase the potential for one or more of our suppliers to experience financial distress or bankruptcy. The inability of our suppliers to deliver products of acceptable quality and in a timely manner or our inability to procure adequate supplies of our products could have a material adverse effect on our business, financial condition or results of operations.

Intellectual Property

     While we have a number of patents issued and additional patent applications pending in the United States, Canada, Europe and Asia, we rely primarily on our trade secrets, trademarks, copyrights and contractual provisions to protect our intellectual property. We attempt to protect our proprietary information through confidentiality agreements and contractual provisions with our customers, suppliers, employees and consultants, and through other security measures. However, the laws of certain countries in which our products are or may be developed, manufactured or sold, including various countries in Asia, may not protect our products and intellectual property rights to the same extent as the laws of the United States, or at all.

     Our ability to compete may be affected by our ability to protect our intellectual property. Although we intend to protect our rights vigorously, there can be no assurance that these measures will be successful.

     We have in the past received notices of claimed infringement of intellectual property rights and been involved in intellectual property litigation. There can be no assurance that third parties will not assert additional claims of infringement of intellectual property rights against us, or against customers who we are contractually obligated to indemnify, with respect to existing and future products. In the event of a patent or other intellectual property dispute, we may be required to expend significant resources to defend such claims, develop non-infringing technology or to obtain licenses to the technology which is the subject of the claim. There can be no assurance that we would be successful in such development or that any such license would be available on commercially reasonable terms, if at all. In the event of litigation to determine the validity of any third party’s claims, such litigation could result in significant expense to us, and divert the efforts of our technical and management personnel, whether or not such litigation is determined in our favor.

     Some of our products are designed to include software or other intellectual property licensed from third parties. None of these licenses relate to core QLogic developed technology, are material to our business, or require payment of amounts that are material.

Environment

     Our operations are subject to regulation under various federal, state, local and foreign laws concerning the environment, including laws addressing the discharge of pollutants into the environment, the management and disposal of hazardous substances and wastes, and the cleanup of contaminated sites. We could incur substantial costs, including cleanup costs, fines and civil or criminal sanctions, and third-party damage or personal injury claims, if we violate or become liable under environmental laws.

     Most of our products are also subject to various laws governing chemical substances in products, including those regulating the manufacture and distribution of chemical substances and those restricting the presence of certain substances in electronic products. We could incur substantial costs, or our products could be restricted from entering certain countries, if our products become non-compliant with environmental laws. We also face increasing complexity in our product design and procurement operations as we adjust to new and future requirements relating to the materials composition of our products. For example, the European Union adopted the Waste Electrical and Electronic Equipment, or WEEE, Directive, which requires European Union countries to enact legislation to make producers of electrical goods financially responsible for specified collection, recycling, treatment and disposal of past and future covered products. These and similar laws adopted in other countries could impose a significant cost of doing business in those countries.

     Environmental costs are presently not material to our results of operations or financial position, and we do not currently anticipate material capital expenditures for environmental control facilities.

Working Capital

     Cash provided by operating activities was $161.8 million for fiscal 2010. For additional information on our working capital, see Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources, included in Part II, Item 7 of this report.

Employees

     We had 1,038 employees as of May 13, 2010. We believe our future prospects will depend, in part, on our ability to continue to attract, train, motivate, retain and manage skilled engineering, sales, marketing and executive personnel. Our employees are not represented by a labor union. We believe that our relations with our employees are good.

Item 1A.		Risk Factors

     Set forth below and elsewhere in this report and in other documents we file with the Securities and Exchange Commission are risks and uncertainties that could cause our actual results of operations to differ materially from the results contemplated by the forward-looking statements contained in this report or otherwise publicly disclosed by the Company.

Economic weakness and uncertainty has resulted in a decrease in information technology spending levels and could result in further deterioration of our revenues and operating results.

     The United States and other countries around the world have been experiencing economic weakness and uncertainty. There has been an erosion of global consumer confidence amidst concerns over declining asset values, energy costs, geopolitical issues, the availability and cost of credit, rising unemployment, and the stability and solvency of financial institutions, financial markets, businesses and sovereign nations. We are unable to predict the likely duration and severity of the disruption in financial markets and adverse economic conditions in the United States and other countries. The economic uncertainty has resulted in a global downturn in information technology, or IT, spending rates, which has negatively impacted our revenue and operating results. Further reductions in IT spending rates could result in longer sales cycles, increased inventory provisions, increased production costs, lower prices for our products and reduced sales volumes. Even if IT spending rates were to increase, we cannot be certain that the market for our networking infrastructure products would be positively impacted. If economic conditions worsen, there are future reductions in either domestic or international IT spending rates, or IT spending rates do not increase, our revenues, operating results and financial condition could deteriorate further.

     As a result of worldwide economic uncertainty, it is extremely difficult for us and our customers to forecast future revenue levels based on historical information and trends. Portions of our expenses are fixed and others are tied to expected levels of revenue. To the extent that we do not achieve our anticipated level of revenue, our operating results could be adversely affected until such expenses are reduced to an appropriate level. In addition, we have implemented various cost-cutting measures in order to better align our revenues and cost structure. We may not be able to identify and implement appropriate further cost savings in a timely manner. Additionally, we may determine that the costs of implementing reductions outweigh the commensurate benefits.

     We are also subject to various counterparty risks as a result of the economic slowdown, including the potential insolvency of key suppliers resulting in product delays, inability of customers to obtain credit to finance purchases of our products and/or potential customer insolvencies, increased risk that customers may delay payments or fail to pay, and counterparty failures, particularly financial institutions, negatively impacting our treasury operations. Any of these risks could have a material adverse effect on our results of operations or financial condition.

Our operating results may fluctuate in future periods, which could cause our stock price to decline.

     We have experienced, and expect to experience in future periods, fluctuations in sales and operating results from quarter to quarter. In addition, there can be no assurance that we will maintain our current gross margins or profitability in the future. A significant portion of our net revenues in each fiscal quarter results from orders booked in that quarter. Orders placed by major customers are typically based on their forecasted sales and inventory levels for our products.

     Fluctuations in our quarterly operating results may also be the result of:

	•		the timing, size and mix of orders from customers;
	•		gain or loss of significant customers;
	•		customer policies pertaining to desired inventory levels of our products;
	•		sales discounts and customer incentives;
	•		the availability and sale of new products;
	•		changes in our average selling prices;
	•		variations in manufacturing capacities, efficiencies and costs;

	•		the availability and cost of components, including silicon chips;
	•		variations in product development costs, especially related to advanced technologies;
	•		variations in operating expenses;
	•		changes in effective income tax rates, including those resulting from changes in tax laws;
	•		our ability to timely produce products that comply with new environmental restrictions or related requirements of our original equipment manufacturer, or OEM, customers;
	•		actual events, circumstances, outcomes and amounts differing from judgments, assumptions and estimates used in determining the value of certain assets (including the amounts of related valuation allowances), liabilities and other items reflected in our consolidated financial statements;
	•		the timing of revenue recognition and revenue deferrals;
	•		gains or losses related to our investment securities;
	•		changes in accounting rules or our accounting policies;
	•		general economic and other conditions affecting the timing of customer orders and capital spending; or
	•		changes in the global economy that impact IT spending.

     In addition, our quarterly results of operations are influenced by competitive factors, including the pricing and availability of our products and our competitors’ products. Furthermore, communications regarding new products and technologies could cause our customers to defer or cancel purchases of our products. Order deferrals by our customers, delays in our introduction of new products, and longer than anticipated design-in cycles for our products have in the past adversely affected our quarterly results of operations. Due to these factors, as well as other unanticipated factors, it is likely that in some future quarter or quarters our operating results will be below the expectations of public market analysts or investors, and as a result, the price of our common stock could significantly decrease.

We expect gross margin to vary over time, and our recent level of gross margin may not be sustainable.

     Our recent level of gross margin may not be sustainable and may be adversely affected by numerous factors, including:

	•		changes in product mix;
	•		changes in manufacturing volumes over which fixed costs are absorbed;
	•		increased price competition;
	•		introduction of new products by us or our competitors, including products with advantages in price, performance or features;
	•		our inability to reduce manufacturing-related or component costs;
	•		entry into new markets or the acquisition of new businesses;
	•		amortization and impairments of purchased intangible assets;
	•		sales discounts and customer incentives;
	•		increases in material, labor or overhead costs;
	•		excess inventory and inventory holding charges;

	•		changes in distribution channels; and
	•		increased warranty costs.

Our stock price may be volatile.

     The market price of our common stock has fluctuated substantially, and there can be no assurance that such volatility will not continue. Several factors could impact our stock price including, but not limited to:

	•		differences between our actual revenues and operating results and the published expectations of public market analysts;
	•		quarterly fluctuations in our revenues and operating results;
	•		introduction of new products or changes in product pricing policies by our competitors or us;
	•		conditions in the markets in which we operate;
	•		changes in market projections by industry forecasters;
	•		changes in estimates of our earnings or rating upgrades/downgrades of our stock by public market analysts;
	•		operating results or forecasts of our major customers or competitors;
	•		rumors or dissemination of false information; and
	•		general economic and geopolitical conditions.

     In addition, stock markets have experienced extreme price and volume volatility in recent years and stock prices of technology companies have been especially volatile. This volatility has had a substantial effect on the market prices of securities of many public companies for reasons frequently unrelated to the operating performance of the specific companies. These broad market fluctuations could adversely affect the market price of our common stock.

Our business is dependent, in large part, on the continued growth of the networking markets that we serve and if these markets do not continue to develop, our business will suffer.

     Our products are used in storage, high performance computing, or HPC, and converged networks, and therefore our business is dependent on these network infrastructure markets. Our success in generating revenue in these markets will depend on, among other things, our ability to:

	•		educate potential OEM customers, distributors, resellers, system integrators, storage system providers and end-user organizations about the benefits of our products;
	•		maintain and enhance our relationships with OEM customers, distributors, resellers, system integrators and storage system providers;
	•		predict and base our products on standards which ultimately become industry standards; and
	•		achieve and maintain interoperability between our products and other equipment and components from diverse vendors.

Our business could be adversely affected by a significant increase in the market acceptance of blade servers.

     Blade server products have gained acceptance in the market over the past few years. Blade servers use custom storage, HPC and converged network infrastructure products, including bladed switches and mezzanine cards, which have lower average selling prices than the network infrastructure products used in a non-blade server environment. If blade servers gain an increased percentage of the overall server market, our business could be adversely affected by the transition to blade server products. This could have a material adverse effect on our business or results of operations.

Our financial condition will be materially harmed if we do not maintain and gain market acceptance of our products.

     The markets in which we compete involve rapidly changing technology, evolving industry standards and continuing improvements in products and services. Our future success depends, in part, on our ability to:

	•		enhance our current products and develop and introduce, in a timely manner, new products that keep pace with technological developments and industry standards;
	•		compete effectively on the basis of price and performance; and
	•		adequately address OEM and end-user customer requirements and achieve market acceptance.

     We believe that to remain competitive, we will need to continue to develop new products, which will require significant investment. Our competitors may be developing alternative technologies, which may adversely affect the market acceptance of our products. Although we continue to explore and develop products based on new technologies, a substantial portion of our revenues is generated today from Fibre Channel technology. If alternative technologies are adopted by the industry, we may not be able to develop products for new technologies in a timely manner. Further, even if alternative technologies do augment Fibre Channel revenues, our products may not be fully developed in time to be accepted by our customers. Even if our new products are developed on time, we may not be able to manufacture them at competitive prices or in sufficient volumes.

     Some of our products are based on the Fibre Channel over Ethernet, or FCoE, protocol. FCoE is a relatively new converged networking technology that provides a unified storage and data network over Enhanced Ethernet, while preserving the investment in existing Fibre Channel infrastructure and storage. As with most emerging technologies, it is expected that the market for FCoE will take a number of years to fully develop and mature. We expect products based on the FCoE protocol to supplement, and perhaps replace, certain products based on the Fibre Channel protocol. As a result, an inability to maintain our market share in the Fibre Channel market and build upon our market share in the FCoE market could have a material adverse effect on our business or results of operations.

We depend on a small number of customers, and any decrease in revenues or cash flows from any one of our major customers could adversely affect our results of operations and cause our stock price to decline.

     A small number of customers account for a substantial portion of our net revenues, and we expect that a small number of customers will continue to represent a substantial portion of our net revenues in the foreseeable future. Our top ten customers accounted for 86%, 84% and 85% of our net revenues for fiscal 2010, 2009 and 2008, respectively. Hewlett-Packard and IBM each accounted for 20% or more of net revenues during fiscal 2010. We are also subject to credit risk associated with the concentration of our accounts receivable. In addition, the worldwide economic slowdown and tightening of credit in financial markets may impact the businesses of our customers, which could have a material adverse effect on our business, financial condition or results of operations.

     Our customers generally order products through written purchase orders as opposed to long-term supply contracts and, therefore, are generally not obligated to purchase products from us for any extended period. Major customers also have significant leverage over us and may attempt to change the terms, including pricing, customer incentives and payment terms, which could have a material adverse effect on our business, financial condition or results of operations. This risk is increased due to the potential for some of these customers to merge with or acquire one or more of our other customers. As our OEM customers are pressured to reduce prices as a result of competitive factors, we may be required to contractually commit to price reductions for our products before we know how, or if, cost reductions can be obtained. If we are unable to achieve such cost reductions, our gross margins could decline and such decline could have a material adverse effect on our business, financial condition or results of operations.

Our business may be subject to seasonal fluctuations and uneven sales patterns in the future.

     A large percentage of our products are sold to customers who experience seasonality and uneven sales patterns in their businesses. As a result, we may experience similar seasonality and uneven sales patterns. We believe this uneven sales pattern is a result of many factors including:

	•		the tendency of our customers to close a disproportionate percentage of their sales transactions in the last month, weeks and days of each quarter;
	•		spikes in sales during the fourth quarter of each calendar year that some of our customers experience; and

•

differences between our quarterly fiscal periods and the fiscal periods of our customers.

     In addition, as our customers increasingly require us to maintain products at hub locations near their facilities, it becomes more difficult for us to predict sales trends. Our uneven sales pattern also makes it extremely difficult to predict the demand of our customers and adjust manufacturing capacity accordingly. If we predict demand that is substantially greater than actual customer orders, we will have excess inventory. Alternatively, if customer orders substantially exceed predicted demand, the ability to assemble, test and ship orders received in the last weeks and days of each quarter may be limited, or at an increased cost, which could have a material adverse effect on quarterly revenues and earnings.

Competition within the markets for our products is intense and includes various established competitors.

     The markets for networking infrastructure components are highly competitive and are characterized by short product life cycles, price erosion, rapidly changing technology, frequent product performance improvements and evolving industry standards. Due to the diversity of products required in storage, HPC and converged networking infrastructure, we compete with many companies. In the traditional enterprise storage Fibre Channel adapter market, our primary competitor is Emulex Corporation, with Brocade Communications Systems, Inc. also participating. In the iSCSI adapter market, our primary competitor is Broadcom Corporation and we also compete indirectly with companies offering software initiator solutions. In the FCoE adapter market, we compete with Emulex Corporation, and recent entry, Brocade Communications Systems, Inc. and we also compete with Ethernet adapter suppliers Broadcom Corporation and Intel Corporation. In the Intelligent Ethernet adapter market, we compete with Intel Corporation, Broadcom Corporation and Emulex Corporation. In the Fibre Channel switch and storage router markets, we compete primarily with Brocade Communications Systems, Inc. and Cisco Systems, Inc. In the InfiniBand adapter and switch markets, we compete primarily with Mellanox Technologies, Ltd. and Voltaire Ltd. We may also compete with some of our server and storage systems customers, some of which have the capability to develop products comparable to those we offer.

     We need to continue to develop products appropriate to our markets to remain competitive as our competitors continue to introduce products with improved features. While we continue to devote significant resources to engineering and development, these efforts may not be successful or competitive products may not be developed and introduced in a timely manner. In addition, while relatively few competitors offer a full range of storage, HPC and converged networking infrastructure products, additional domestic and foreign manufacturers may increase their presence in these markets. We may not be able to compete successfully against these or other competitors. If we are unable to design, develop or introduce competitive new products on a timely basis, our future operating results may be materially and adversely affected.

We expect the pricing of our products to continue to decline, which could reduce our revenues, gross margins and profitability.

     We expect the average unit prices of our products (on a like-for-like product comparison basis) to decline in the future as a result of competitive pricing pressures, increased sales discounts and customer incentives, new product introductions by us or our competitors, or other factors. In addition, there is a general market trend of customers migrating away from the distribution channel for product purchases to OEMs, where products have a lower average unit price. If we are unable to offset these factors by increasing sales volumes, or reducing product manufacturing costs, our total revenues and gross margins may decline. In addition, we must develop and introduce new products and product enhancements. Moreover, most of our expenses are fixed in the short-term or incurred in advance of receipt of corresponding revenues. As a result, we may not be able to decrease our spending to offset any unexpected shortfall in revenues. If this occurs, our revenues, gross margins and profitability could decline.

Our distributors may not adequately stock and sell our products and their reseller customers may purchase products from our competitors, which could negatively affect our results of operations.

     Our distributors generally offer a diverse array of products from several different manufacturers and suppliers. Accordingly, we are at risk that these distributors may give higher priority to stocking and selling products from other suppliers, thus reducing their efforts and ability to sell our products. A reduction in sales efforts by our current distributors could materially and adversely impact our business or results of operations. In addition, if we decrease our distributor-incentive programs (i.e., competitive pricing and rebates), our distributors may decrease the amount of product purchased from us. This could result in a change of business behavior, and distributors may decide to decrease the amount of product held and reduce their inventory levels, which could impact availability of our products to their customers.

     As a result of these factors regarding our distributors or other unrelated factors, the reseller customers of our distributors could decide to purchase products developed and manufactured by our competitors. Any loss of demand for our products by value-added resellers and system integrators could have a material adverse effect on our business or results of operations.

We are dependent on sole source and limited source suppliers for certain key components.

     Certain key components used in the manufacture of our products are purchased from single or limited sources. Application-specific integrated circuits, or ASICs, are purchased from single sources and microprocessors, certain connectors, logic chips, power supplies and programmable logic devices are purchased from limited sources. If one of these suppliers experiences an interruption in its ability to supply our needs, or chooses to sever its relationship with us, we may be unable to produce certain of our products, which could result in the loss of customers and have a material adverse effect on our results of operations. The global economic downturn and tightening of credit in financial markets may adversely impact our suppliers by limiting their ability to finance their business operations and as a result limit their ability to supply products to us.

We are dependent on worldwide third-party subcontractors and contract manufacturers.

     Third-party subcontractors located outside the United States assemble and test certain products for us. To the extent that we rely upon third-party subcontractors to perform these functions, we will not be able to directly control product delivery schedules and quality assurance. This lack of control may result in product shortages or quality assurance problems that could delay shipments of products or increase manufacturing, assembly, testing or other costs. If any of these subcontractors experience capacity constraints or financial difficulties, suffer damage to their facilities, experience power outages or any other disruption of assembly or testing capacity, we may not be able to obtain alternative assembly and testing services in a timely manner.

     In addition, the loss of any of our major third-party contract manufacturers could significantly impact our ability to produce products for an indefinite period of time. Qualifying a new contract manufacturer and commencing volume production is a lengthy and expensive process. Some customers will not purchase any products, other than a limited number of evaluation units, until they qualify the manufacturing line for the product, and we may not always be able to satisfy the qualification requirements of these customers. If we are required to change a contract manufacturer or if a contract manufacturer experiences delays, disruptions, capacity constraints, component parts shortages or quality control problems in its manufacturing operations, shipment of our products to our customers could be delayed, resulting in loss or postponement of revenues and potential harm to our competitive position and relationships with customers. In addition, the global economic weakness and tightening of credit markets could adversely affect our third-party subcontractors or contract manufacturers and increase the potential for one or more of them to experience financial distress or bankruptcy.

 Our investment securities portfolio could experience a decline in market value, which could materially and adversely affect our financial results.

     As of March 28, 2010, we held short-term investment securities totaling $185.4 million. We invest primarily in debt securities, the majority of which are high investment grade, and we limit the exposure to credit risk through diversification and investment in highly-rated securities. However, investing in highly-rated securities does not entirely mitigate the risk of potential declines in market value. During fiscal 2009, we recorded impairment charges related to investment securities, including securities issued by companies in the financial services sector that had previously been rated AA or higher. A deterioration in the economy, including tightening of credit markets or significant volatility in interest rates, could cause declines in value of our investment securities or could impact the liquidity of the portfolio. If market conditions deteriorate significantly, our results of operations or financial condition could be materially and adversely affected.

     Our investment securities include $22.3 million of investments in auction rate debt and preferred securities (ARS), the majority of which are rated AA or higher. During late fiscal 2008, the market auctions of many ARS began to fail, including auctions for our ARS. The underlying assets for auction rate debt securities in our portfolio are student loans, substantially all of which are backed by the federal government under the Federal Family Education Loan Program. The underlying assets of our auction rate preferred securities are the respective funds’ investment portfolios.

     In November 2008, we entered into an agreement with the broker for all of the ARS we currently hold, which provides us with certain rights (ARS Rights), in exchange for the release of potential claims and damages against the broker. The ARS Rights entitle us to sell the related ARS back to the broker for a price equal to the liquidation preference of the ARS plus accrued but unpaid dividends or interest, if any, which price is referred to as “par.” The ARS Rights may be exercised by us at any time between June 30, 2010 and July 2, 2012, if the securities are not earlier redeemed or sold. Under the ARS Rights, the broker may, at its discretion, purchase the

ARS at any time through July 2, 2012 without prior notice to us and must pay us par value for the ARS within one day of the sale transaction settlement. While we expect to ultimately recover our investments in the ARS at par, we may be unable to liquidate some or all of our ARS should we need or desire to access the funds invested in those securities prior to redemption by the issuer or the exercise of the ARS Rights. There is also a risk that our broker will default on its obligation to purchase the ARS in the event that we exercise the ARS Rights.

Our products are complex and may contain undetected software or hardware errors that could lead to an increase in our costs, reduce our net revenues or damage our reputation.

     Our products are complex and may contain undetected software or hardware errors when first introduced or as newer versions are released. We are also exposed to risks associated with latent defects in existing products and to risks that components purchased from third-party subcontractors and incorporated into our products may not meet our specifications or may otherwise fail prematurely. From time to time, we have found errors in existing, new or enhanced products. In addition, our products are frequently combined with other products, including software, from other vendors, and these products often need to interface with existing networks, each of which have different specifications and utilize multiple protocol standards and products from other vendors. As a result, when problems occur, it may be difficult to identify the source of the problem. The occurrence of hardware or software errors could adversely affect the sales of our products, cause us to incur significant warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations problems.

The migration of our customers toward new products could adversely affect our results of operations.

     As new or enhanced products are introduced, we must successfully manage the transition from older products in order to minimize the effects of product inventories that may become excess and obsolete, as well as ensure that sufficient supplies of new products can be delivered to meet customer demand. Our failure to manage the transition to newer products in the future or to develop and successfully introduce new products and product enhancements could adversely affect our business or results of operations. When we introduce new products and product enhancements, we face risks relating to product transitions, including risks relating to forecasting demand. Any such adverse event could have a material adverse effect on our business, financial condition or results of operations.

     Historically, the technology industry has developed higher performance ASICs, which create chip-level solutions that replace selected board-level or box-level solutions at a significantly lower average selling price. We have previously offered ASICs to customers for certain applications that have effectively resulted in a lower-priced solution when compared to an adapter solution. This transition to ASICs may also occur with respect to other current and future products. The result of this transition may have an adverse effect on our business, financial condition or results of operations. In the future, a similar adverse effect to our business could occur if there were rapid shifts in customer purchases from our midrange networking infrastructure products to lower-cost products.

Unanticipated changes in our tax provisions or adverse outcomes resulting from examination of our income tax returns could adversely affect our results of operations.

     We are subject to income taxes in the United States and various foreign jurisdictions. Our effective income tax rates have recently been and could in the future be adversely affected by changes in tax laws or interpretations of those tax laws, by changes in the mix of earnings in countries with differing statutory tax rates, by discovery of new information in the course of our tax return preparation process, or by changes in the valuation of our deferred tax assets and liabilities. Our effective income tax rates are also affected by intercompany transactions for licenses, services, funding and other items. Given the increased global scope of our operations, and the complexity of global tax and transfer pricing rules and regulations, it has become increasingly difficult to estimate earnings within each tax jurisdiction. If actual earnings within a tax jurisdiction differ materially from our estimates, we may not achieve our expected effective tax rate. Additionally, our effective tax rate may be impacted by the tax effects of acquisitions, examinations by tax authorities, stock-based compensation, uncertain tax positions and newly enacted tax legislation. For example, proposed changes to certain U.S. tax rules for U.S. corporations doing business outside the United States include limiting the ability of U.S. corporations to deduct certain expenses attributable to offshore earnings, modifying the foreign tax credit rules and accelerating taxes related to certain transfers of intangible assets offshore. Although the scope of the proposed changes is unclear, it is possible that these or other changes in the U.S. tax laws could increase our effective tax rate and adversely affect our profitability. Finally, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities which may result in the assessment of additional income taxes. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provisions for income taxes. However, unanticipated outcomes from these continuous examinations could have a material adverse effect on our financial condition or results of operations.

Environmental compliance costs could adversely affect our results of operations.

     We are subject to various federal, state, local and foreign laws concerning environmental protection, including laws addressing the discharge of pollutants into the environment, the management and disposal of hazardous substances and wastes, the cleanup of contaminated sites, the content of our products and the recycling, treatment and disposal of our products. In particular, we face increasing complexity in our product design and procurement operations as we adjust to new and future requirements relating to the chemical and material composition of our products, their safe use, the energy consumption associated with those products and product take-back legislation (i.e., legislation that makes producers of electrical goods financially responsible for specified collection, recycling, treatment and disposal of past and future covered products). We could incur substantial costs, our products could be restricted from entering certain jurisdictions, and we could face other sanctions, if we were to violate or become liable under environmental laws or if our products become non-compliant with environmental laws. Our potential exposure includes fines and civil or criminal sanctions, third-party property damage or personal injury claims, and clean up costs. Further, liability under some environmental laws relating to contaminated sites can be imposed retroactively, on a joint and several basis, and without any finding of noncompliance or fault. The amount and timing of costs under environmental laws are difficult to predict and could have a material adverse effect on our results of operations.

Because we have operations in foreign countries and depend on foreign customers and suppliers, we are subject to international economic, currency, regulatory, political and other risks that could harm our business, financial condition and results of operations.

     International revenues accounted for 54%, 52% and 49% of our net revenues for fiscal 2010, 2009 and 2008, respectively. We expect that international revenues will continue to account for a significant percentage of our net revenues for the foreseeable future. In addition, we maintain operations in foreign countries and a significant portion of our inventory purchases are from suppliers that are located outside the United States. As a result, we are subject to several risks, which include:

	•		a greater difficulty of administering and managing our business globally;
	•		compliance with multiple and potentially conflicting regulatory requirements, such as import or export requirements, tariffs and other barriers;
	•		less effective intellectual property protections;
	•		currency fluctuations;
	•		overlapping or differing tax structures;
	•		political and economic instability, including terrorism and war; and
	•		general trade restrictions.

     As of March 28, 2010, our international subsidiaries hold approximately 47% of our total cash, cash equivalents and investment securities. These holdings by our international subsidiaries consist primarily of U.S. dollar denominated cash, money market and certificate of deposit accounts. Certain foreign regulations could impact our ability to transfer funds to the United States. Additionally, should we decide to repatriate cash held outside of the United States, we may incur a significant tax obligation.

     Our international sales are invoiced in U.S. dollars and, accordingly, if the relative value of the U.S. dollar in comparison to the currency of our foreign customers should increase, the resulting effective price increase of our products to such foreign customers could result in decreased sales. In addition, a significant portion of our inventory is purchased from international suppliers, who invoice us in U.S. dollars. If the relative value of the U.S. dollar in comparison to the currency of our foreign suppliers should decrease, our suppliers may increase prices which could result in a decline of our gross margin. Any of the foregoing factors could have a material adverse effect on our business, financial condition or results of operations.

     In addition, we and our customers are subject to various import and export regulations of the United States government and other countries. Certain government export regulations apply to the encryption or other features contained in some of our products. Changes in or violations of any such import or export regulations could materially and adversely affect our business, financial condition or results of operations.

     Moreover, in many foreign countries, particularly in those with developing economies, it is common to engage in business practices that are prohibited by regulations applicable to us, such as the Foreign Corrupt Practices Act. Although we implement policies and procedures designed to ensure compliance with these laws, our employees, contractors and agents, as well as those companies to which we outsource certain of our business operations, may take actions in violation of our policies. Any such violation, even if prohibited by our policies, could have a material adverse effect on our business, financial condition or results of operations.

We may engage in mergers, acquisitions and strategic investments and these activities may adversely affect our results of operations and stock price.

     Our future growth may depend in part on our ability to identify and acquire complementary businesses, technologies or product lines that are compatible with our existing business. Mergers and acquisitions involve numerous risks, including:

	•		the failure of markets for the products of acquired companies to develop as expected;
	•		uncertainties in identifying and pursuing target companies;
	•		difficulties in the assimilation of the operations, technologies and products of the acquired companies;
	•		the existence of unknown defects in acquired companies’ products or assets that may not be identified due to the inherent limitations involved in the due diligence process of an acquisition;
	•		the diversion of management’s attention from other business concerns;
	•		risks associated with entering markets or conducting operations with which we have no or limited direct prior experience;
	•		risks associated with assuming the legal obligations of acquired companies;
	•		risks related to the effect that acquired companies’ internal control processes might have on our financial reporting and management’s report on our internal control over financial reporting;
	•		the potential loss of, or impairment of our relationships with, current customers or failure to retain the acquired companies’ customers;
	•		the potential loss of key employees of acquired companies; and
	•		the incurrence of significant exit charges if products or technologies acquired in business combinations are unsuccessful.

     Further, we may never realize the perceived benefits of a business combination. Acquisitions by us could negatively impact gross margins or dilute stockholders’ investment and cause us to incur debt, contingent liabilities and amortization/impairment charges related to intangible assets, all of which could materially and adversely affect our financial position or results of operations. In addition, our effective tax rate for future periods could be negatively impacted by mergers and acquisitions.

     We have made, and could make in the future, investments in technology companies, including privately-held companies in a development stage. Many of these private equity investments are inherently risky because the companies’ businesses may never develop, and we may incur losses related to these investments. In addition, we may be required to write down the carrying value of these investments to reflect other-than-temporary declines in their value, which could have a material adverse effect on our financial position and results of operations.

If we are unable to attract and retain key personnel, we may not be able to sustain or grow our business.

     Our future success largely depends on our key engineering, sales, marketing and executive personnel, including highly skilled semiconductor design personnel and software developers, and in particular, our Chief Executive Officer, H.K. Desai. If we lose the services of Mr. Desai or other key personnel or fail to hire personnel for key positions, our business could be adversely affected. We believe that the market for key personnel in the industries in which we compete is highly competitive. In particular, periodically we have experienced difficulty in attracting and retaining qualified engineers and other technical personnel and anticipate that competition for such personnel will increase in the future. Our recent implementation of various cost saving measures, as well as past reductions in force, could negatively impact employee morale and potentially make attracting and retaining qualified employees more difficult in

the future. As a result, we may not be able to attract and retain key personnel with the skills and expertise necessary to develop new products in the future or to manage our business, both in the United States and abroad.

     We have historically used stock options and other forms of stock-based compensation as key components of our total employee compensation program in order to align employees’ interests with the interests of our stockholders, encourage retention of key personnel, and provide competitive compensation packages. However, applicable stock exchange listing standards relating to obtaining stockholder approval of equity compensation plans could make it more difficult or expensive for us to grant stock-based awards to employees in the future, which may result in changes in our stock-based compensation strategy. These and other developments relating to the provision of stock-based compensation to employees could make it more difficult to attract, retain and motivate key personnel.

We may experience difficulties in transitioning to smaller geometry process technologies.

     We expect to continue to transition our semiconductor products to increasingly smaller line width geometries. This transition requires us to modify the manufacturing processes for our products and to redesign some products as well as standard cells and other integrated circuit designs that we may use in multiple products. We periodically evaluate the benefits, on a product-by-product basis, of migrating to smaller geometry process technologies. Currently, most of our products include ASICs which are manufactured in 180, 130, 90 and 65 nanometer geometry processes. In addition, we continually evaluate smaller geometries. In the past, we have experienced some difficulties in shifting to smaller geometry process technologies or new manufacturing processes, which resulted in reduced manufacturing yields, delays in product deliveries and increased expenses. We may face similar difficulties, delays and expenses as we continue to transition our products to smaller geometry processes.

Our proprietary rights may be inadequately protected and difficult to enforce.

     In some jurisdictions, we have patent protection on certain aspects of our technology. However, we rely primarily on trade secrets, trademarks, copyrights and contractual provisions to protect our proprietary rights. There can be no assurance that these protections will be adequate to protect our proprietary rights, that others will not independently develop or otherwise acquire equivalent or superior technology, or that we can maintain such technology as trade secrets. There also can be no assurance that any patents we possess will not be invalidated, circumvented or challenged. We have taken steps in several jurisdictions to enforce our trademarks against third parties. No assurances can be given that we will ultimately be successful in protecting our trademarks. The laws of certain countries in which our products are or may be developed, manufactured or sold, including various countries in Asia, may not protect our products and intellectual property rights to the same extent as the laws of the United States, or at all. If we fail to protect our intellectual property rights, our business could be negatively impacted.

Disputes relating to claimed infringement of intellectual property rights may adversely affect our business.

     We have in the past received notices of claimed infringement of intellectual property rights and been involved in intellectual property litigation. There can be no assurance that third parties will not assert future claims of infringement of intellectual property rights against us, or against customers who we are contractually obligated to indemnify, with respect to existing and future products. In addition, individuals and groups are purchasing intellectual property assets for the sole purpose of making claims of infringement and attempting to extract settlements from companies such as ours. Although patent and intellectual property disputes may be settled through licensing or similar arrangements, costs associated with these arrangements may be substantial and the necessary licenses or similar arrangements may not be available to us on satisfactory terms, or at all. As a result, we could be prevented from manufacturing and selling some of our products. In addition, if we litigate these kinds of claims, the litigation could be expensive, time consuming and could divert management’s attention from other matters and there is no guarantee we would prevail. Our business could suffer regardless of the outcome of the litigation. Our supply of silicon chips and other components can also be interrupted by intellectual property infringement claims against our suppliers.

If we fail to carefully manage the use of “open source” software in our products, we may be required to license key portions of our products on a royalty-free basis or expose key parts of our source code.

     Certain of our software may be derived from “open source” software that is generally made available to the public by its authors and/or other third parties. Such open source software is often made available to us under licenses, such as the GNU General Public License (GPL), which impose certain obligations on us in the event we were to distribute derivative works of the open source software. These obligations may require us to make source code for the derivative works available to the public, and/or license such derivative works under a particular type of license, rather than the forms of licenses customarily used to protect our intellectual property. In the event the copyright holder of any open source software were to successfully establish in court that we had not

complied with the terms of a license for a particular work, we could be required to release the source code of that work to the public and/or stop distribution of that work.

Our business could be materially adversely affected by changes in regulations or standards regarding energy use of our products.

     We continually seek ways to increase the energy efficiency of our products. Recent analyses have estimated the amount of global carbon emissions that are due to information technology products. As a result, governmental and non-governmental organizations have turned their attention to development of regulations and standards to drive technological improvements and reduce the amount of carbon emissions. There is a risk that the rush to development of these standards will not fully address the complexity of the technology developed by the IT industry or will favor certain technological approaches. Depending on the regulations or standards that are ultimately adopted, compliance could adversely affect our business, results of operations or financial condition.

Computer viruses and other forms of tampering with our computer systems or servers may disrupt our operations and adversely affect our business.

     Despite our implementation of network security measures and anti-virus defenses, our servers are vulnerable to computer viruses, break-ins and similar disruptions from unauthorized tampering with our computer systems. Any such event could have a material adverse effect on our business, results of operations or financial condition.

Our facilities and the facilities of our suppliers and customers are located in regions that are subject to natural disasters.

     Our California facilities, including our principal executive offices, our principal design facilities and our critical business operations, are located near major earthquake faults. We are not specifically insured for earthquakes or other natural disasters. Any personal injury or damage to the facilities as a result of such occurrences could have a material adverse effect on our business, results of operations or financial condition. Additionally, we have operations, suppliers and customers in regions which have historically experienced natural disasters. Any earthquake or other natural disaster, including a hurricane, volcanic eruption, tsunami or fire, affecting any of these regions could adversely affect our business, results of operations and financial condition.

     None.

Item 2.		Properties

     Our principal product development, operations, sales and corporate offices are located in three buildings comprising approximately 165,000 square feet in Aliso Viejo, California. We own each of these buildings. We also lease one building comprising approximately 100,000 square feet in Shakopee, Minnesota, that houses product development and operations teams for many of our Network Products. We lease an operations, sales and fulfillment facility located in Dublin, Ireland. In addition, we lease facilities in Mountain View and Roseville, California; King of Prussia, Pennsylvania; and Pune and Bangalore, India. We also maintain sales offices at various locations in the United States, Europe and Asia. We believe that our existing properties, including both owned and leased sites, are in good condition and suitable for the conduct of our business.

Item 3.		Legal Proceedings

     Various lawsuits, claims and proceedings have been or may be instituted against us. The outcome of litigation cannot be predicted with certainty and some lawsuits, claims and proceedings may be disposed of unfavorably to us. Many intellectual property disputes have a risk of injunctive relief and there can be no assurance that a license will be granted. Injunctive relief could have a material adverse effect on our financial condition or results of operations. Based on an evaluation of matters that are pending or asserted, we believe the disposition of such matters will not have a material adverse effect on our financial condition or results of operations.

Overview

     We are a designer and supplier of network infrastructure products that enhance, manage and support the transmission of data from computer servers to storage systems and from computer servers to other servers. Our products are used in connection with three distinct types of networks: Storage Networks, High Performance Computing, or HPC, Networks, and Converged Networks. Storage Networks are used to provide critical data across widely-distributed environments and primarily use Fibre Channel technology. HPC Networks allow the utilization of advanced parallel processing over multiple servers and typically are used for applications where very large amounts of data must be processed quickly and efficiently. The HPC Network products that we sell use InfiniBand® technology. Converged Networks are designed to address the evolving data center by consolidating and unifying various classes of connectivity and network traffic.

     We classify our products into three broad categories: Host Products, Network Products and Silicon Products. Host Products consist of Fibre Channel and Internet Small Computer Systems Interface, or iSCSI, host bus adapters; InfiniBand® host channel adapters; Fibre Channel over Ethernet, or FCoE, converged network adapters or CNAs; and Intelligent Ethernet adapters, or IEAs. Network Products consist of Fibre Channel switches, including stackable edge switches, bladed switches, virtualized pass-through modules, and high-port count modular-chassis switches; InfiniBand switches, including high-end multi-protocol directors, edge and bladed switches; Enhanced Ethernet pass-through modules; and storage routers for bridging Fibre Channel, FCoE and iSCSI networks. Silicon Products consist of Fibre Channel controllers, iSCSI controllers, converged network controllers and Ethernet controllers.

     Our products are sold worldwide, primarily to original equipment manufacturers, or OEMs, and distributors. Our customers rely on our various networking infrastructure products to deliver solutions to information technology professionals in virtually every business sector. Our products are found primarily in server, workstation and storage subsystem solutions that are used by small, medium and large enterprises with critical business data requirements. These products are incorporated in solutions from a number of storage system and computer system OEM customers, including Cisco Systems, Inc., Dell Inc., EMC Corporation, Hewlett-Packard Company, International Business Machines Corporation, NetApp, Inc., Oracle Corporation and many others.

     We use a fifty-two/fifty-three week fiscal year ending on the Sunday nearest March 31. Fiscal years 2010, 2009 and 2008 each comprised fifty-two weeks and ended on March 28, 2010, March 29, 2009 and March 30, 2008, respectively.

Business Combination

     In April 2009, we acquired NetXen, Inc. (NetXen) in a merger transaction. Cash consideration was $17.6 million for all outstanding NetXen capital stock. NetXen developed, marketed and sold Ethernet adapter and controller products targeted at the enterprise server market. The acquisition expanded our product portfolio to include Ethernet networking products that are complementary to our existing products. The acquisition also expanded our expertise to better address a wider range of emerging customer requirements for converged networks.

Fiscal Year and Fourth Quarter Financial Highlights and Other Information

     Net revenue for fiscal 2010 was $549.1 million compared to $633.9 million in fiscal 2009. Net income for fiscal 2010 was $54.9 million, or $0.47 per diluted share, compared to $108.8 million, or $0.85 per diluted share, in fiscal 2009. In addition, we generated $161.8 million in cash from operations and used $163.4 million of cash to purchase our common stock under our stock repurchase program during fiscal 2010.

     A summary of the key factors and significant events which impacted our financial performance during the fourth quarter of fiscal 2010 are as follows:

	•		Net revenues of $145.7 million for the fourth quarter of fiscal 2010 increased 12% from $130.5 million in the fourth quarter of fiscal 2009. Revenue from Host Products was $103.7 million and increased from $88.4 million in the same quarter last year and revenue from Network Products was $22.6 million compared to $25.1 million in the same quarter of fiscal 2009.
	•		Gross profit as a percentage of net revenues was 65.1% for the fourth quarter of fiscal 2010, compared to 65.9% for the fourth quarter of fiscal 2009.
	•		Operating income as a percentage of net revenues for the fourth quarter of fiscal 2010 increased to 18.8% from 18.3% in the fourth quarter of fiscal 2009.
	•		Net loss was $4.8 million, or $0.04 per diluted share, in the fourth quarter of fiscal 2010, compared to net income of $19.2 million, or $0.16 per diluted share, in the fourth quarter of fiscal 2009. Our net loss in the fourth quarter of fiscal 2010 included a $29.7 million tax charge related to our globalization initiative.
	•		Cash, cash equivalents and investment securities was $375.7 million at March 28, 2010, compared to $378.3 million at March 29, 2009.
	•		Accounts receivable was $73.3 million as of March 28, 2010, compared to $68.5 million as of March 29, 2009. Days sales outstanding (DSO) in receivables as of March 28, 2010 decreased to 46 days from 48 days as of March 29, 2009.
	•		Inventories as of March 28, 2010 decreased to $19.4 million from $40.3 million as of March 29, 2009. Our annualized inventory turns in the fourth quarter of fiscal 2010 increased to 10.5 turns from 4.4 turns in the fourth quarter of fiscal 2009.

     As a result of worldwide economic weakness and uncertainty, it is extremely difficult for us and our customers to forecast future revenue levels based on historical information and trends. Portions of our expenses are fixed and others are tied to expected levels of revenue. To the extent that we do not achieve our anticipated level of revenue, our operating results could be adversely affected until such expenses are reduced to an appropriate level.

Results of Operations

Net Revenues

     A summary of our net revenues by product category is as follows:

		2010				2009				2008
		(Dollars in millions)
Net revenues:
Host Products		$	396.5			$	440.9			$	437.9
Network Products			99.5				117.6				101.8
Silicon Products			42.4				61.4				44.3
Royalty and Service			10.7				14.0				13.9
Total net revenues		$	549.1			$	633.9			$	597.9
Percentage of net revenues:
Host Products			72	%			70	%			73	%
Network Products			18				18				17
Silicon Products			8				10				8
Royalty and Service			2				2				2
Total net revenues			100	%			100	%			100	%

     Historically, the global marketplace for network infrastructure solutions has expanded in response to the information storage requirements of enterprise business environments, as well as the market for solutions in high performance computing environments. These markets have been characterized by rapid advances in technology and related product performance, which has generally resulted in declining average selling prices over time. In general, our revenues have been favorably affected by increases in units sold as a result of market expansion and the release of new products. The favorable effect on our revenues as a result of increases in volume has been partially offset by the impact of declining average selling prices.

     The United States and other countries around the world have been experiencing economic weakness and uncertainty. This economic uncertainty has resulted in a global downturn in information technology spending rates, which has negatively impacted our revenue and operating results. Accordingly, it is extremely difficult for us to forecast future sales levels and historical information may not be indicative of future trends.

     Our net revenues are derived primarily from the sale of Host Products, Network Products and Silicon Products. Net revenues decreased 13% to $549.1 million for fiscal 2010 from $633.9 million for fiscal 2009. This decrease was primarily the result of a $44.4 million, or 10%, decrease in revenue from Host Products; an $18.1 million, or 15%, decrease in revenue from Network Products; and a $19.0 million, or 31%, decrease in revenue from Silicon Products. The decrease in revenue from Host Products was primarily due to a 9% decrease in the quantity of host bus adapters sold and a 6% decrease in the average selling prices of these products, partially offset by an approximately 800% increase in revenue from the early market acceptance of FCoE adapters and the addition of Ethernet adapters as a result of the NetXen acquisition. The decrease in revenue from Network Products was primarily due to an 8% decrease in the number of Fibre Channel switches sold and a 12% decrease in the average selling prices of these products. The decrease in revenue from Silicon Products was due primarily to an 18% decrease in the units of protocol chips sold, an 11% decrease in the average selling prices of these products and a $3.8 million decrease in revenue from management controller chips, as these products reached end-of-life in fiscal 2009. Net revenues for fiscal 2010 included $10.7 million of royalty and service revenue compared with $14.0 million of royalty and service revenue for fiscal 2009. Royalty and service revenues are unpredictable and we do not expect them to be significant to our overall revenues.

     Net revenues increased 6% to $633.9 million for fiscal 2009 from $597.9 million for fiscal 2008. This increase was primarily the result of a $3.0 million, or 1%, increase in revenue from Host Products; a $15.8 million, or 16%, increase in revenue from Network Products; and a $17.1 million, or 39%, increase in revenue from Silicon Products. The increase in revenue from Host Products was primarily due to an 8% increase in the quantity of host bus adapters sold, partially offset by a 7% decrease in average selling prices of these products. The increase in revenue from Network Products was primarily due to a 40% increase in the number of Fibre Channel switches sold, partially offset by a 21% decrease in the average selling prices of these products, and a 32% increase in the number of InfiniBand switches sold, partially offset by an 11% decrease in the average selling prices of these products. The increase in revenue from Silicon Products from the prior year was due primarily to a 32% increase in the units of protocol chips sold. Net revenues for fiscal 2009 included $14.0 million of royalty and service revenue compared with $13.9 million of royalty and service revenue for fiscal 2008.

     A small number of our customers account for a substantial portion of our net revenues, and we expect that a small number of customers will continue to represent a substantial portion of our net revenues for the foreseeable future. Our top ten customers accounted for 86%, 84% and 85% of net revenues during fiscal 2010, 2009 and 2008, respectively.

     A summary of our customers, including their manufacturing subcontractors, that represent 10% or more of our net revenues is as follows:

		2010				2009				2008
Hewlett-Packard			24	%			21	%			20	%
IBM			20	%			18	%			16	%
Sun Microsystems (acquired by Oracle in fiscal 2010)			*				11	%			11	%

     We believe that our major customers continually evaluate whether or not to purchase products from alternative or additional sources. Accordingly, there can be no assurance that a major customer will not reduce, delay or eliminate its purchases from us. Any such reduction, delay or loss of purchases could have a material adverse effect on our business, financial condition or results of operations.

     Net revenues by geographic area are as follows:

		2010				2009				2008
						(In millions)
United States		$	250.3			$	303.7			$	305.2
Asia-Pacific and Japan			138.8				139.9				113.1
Europe, Middle East and Africa			127.0				154.5				144.6
Rest of world			33.0				35.8				35.0
		$	549.1			$	633.9			$	597.9

     Revenues by geographic area are presented based upon the country of destination, which is not necessarily indicative of the location of the ultimate end-user of our products. Net revenues from customers in China were $72.3 million, $58.5 million and $42.4 million for fiscal 2010, 2009 and 2008, respectively. No individual country other than the United States and China represented 10% or more of net revenues for any of the years presented.

Gross Profit

     Gross profit represents net revenues less cost of revenues. Cost of revenues consists primarily of the cost of purchased products, assembly and test services; costs associated with product procurement, inventory management, logistics and product quality; and the amortization and impairment of purchased intangible assets. A summary of our gross profit and related percentage of net revenues is as follows:

		2010				2009				2008
		(Dollars in millions)
Gross profit		$	352.9			$	423.8			$	391.9
Percentage of net revenues			64.3	%			66.9	%			65.6	%

     Gross profit for fiscal 2010 decreased $70.9 million, or 17%, from gross profit for fiscal 2009 and decreased as a percentage of revenue to 64.3% for fiscal 2010 from 66.9% for the prior year. The decrease in gross profit percentage was primarily due to lower volumes to absorb manufacturing costs, a change in product mix and a $3.5 million one-time royalty in fiscal 2009, partially offset by a $5.4 million decrease in amortization of purchased intangible assets.

     Gross profit for fiscal 2009 increased $31.9 million, or 8%, from gross profit for fiscal 2008 and increased as a percentage of revenue to 66.9% in fiscal 2009 from 65.6% for the prior year. The increase in gross profit percentage was primarily the result of manufacturing related efficiencies and a decline of $3.5 million in amortization and impairment of purchased intangible assets in fiscal 2009.

     Our ability to maintain our current gross profit percentage can be significantly affected by factors such as manufacturing volumes over which fixed costs are absorbed, sales discounts and customer incentives, component costs, the mix of products shipped, the transition to new products, competitive price pressures, the timeliness of volume shipments of new products, the level of royalties received, our ability to achieve manufacturing cost reductions, and amortization and impairments of purchased intangible assets. We anticipate that it will be increasingly difficult to reduce manufacturing costs. As a result of these and other factors, it may be difficult to maintain our gross profit percentage consistent with historical periods and it may decline in the future.

Operating Expenses

     Our operating expenses are summarized in the following table:

		2010				2009				2008
		(Dollars in millions)
Operating expenses:
Engineering and development		$	136.8			$	133.2			$	134.7
Sales and marketing			77.6				87.0				84.2
General and administrative			34.2				32.6				34.0
Special charges			5.2				4.1				5.3
Total operating expenses		$	253.8			$	256.9			$	258.2
Percentage of net revenues:
Engineering and development			24.9	%			21.0	%			22.5	%
Sales and marketing			14.1				13.7				14.1
General and administrative			6.2				5.2				5.7
Special charges			1.0				0.6				0.9
Total operating expenses			46.2	%			40.5	%			43.2	%

     Engineering and Development. Engineering and development expenses consist primarily of compensation and related employee benefit costs, service and material costs, occupancy and equipment costs and related computer support costs. During fiscal 2010, engineering and development expenses increased to $136.8 million from $133.2 million in fiscal 2009. The increase was primarily due to a $3.1 million increase in stock-based compensation, including $0.8 million related to stock-based awards issued to employees that joined QLogic in connection with the acquisition of NetXen.

     During fiscal 2009, engineering and development expenses decreased to $133.2 million from $134.7 million in fiscal 2008. The decrease was primarily due to a $0.6 million decrease in stock-based compensation that resulted from headcount reductions in the fourth quarter of fiscal 2009, a $0.9 million decrease in cash compensation and benefit costs and a $0.7 million decrease in occupancy and related computer support costs that both resulted from a net reduction in headcount, including a reduction in headcount related to the consolidation and elimination of certain engineering activities during fiscal 2008. These decreases were partially offset by a $1.2 million increase in depreciation and equipment costs.

     We believe continued investments in engineering and development activities are critical to achieving future design wins, expansion of our customer base and revenue growth opportunities.

     Sales and Marketing. Sales and marketing expenses consist primarily of compensation and related employee benefit costs, sales commissions, promotional activities and travel for sales and marketing personnel. Sales and marketing expenses decreased to $77.6 million for fiscal 2010 from $87.0 million for fiscal 2009. The decrease in sales and marketing expenses was due primarily to a $4.6 million decrease in promotional costs, including the costs for certain sales and marketing programs, and a $0.7 million decrease in travel costs, both related to our cost-cutting measures implemented in the second half of fiscal 2009. In addition, cash compensation and related employee benefit costs decreased by $1.3 million, primarily due to decreased commissions as a result of lower revenues; amortization of purchased intangible assets decreased by $1.3 million, due to an intangible asset becoming fully amortized during fiscal 2010; and occupancy and related computer support costs decreased by $1.0 million. These decreases were partially offset by a $1.4 million increase in stock-based compensation expense.

     Sales and marketing expenses increased to $87.0 million for fiscal 2009 from $84.2 million for fiscal 2008. The increase in sales and marketing expenses was due primarily to a $2.4 million increase in salaries due to increased average headcount during fiscal 2009, a $1.7 million increase in occupancy and related computer support costs and a $1.4 million increase in commissions. These increases were partially offset by a $2.2 million decrease in promotional costs, including our costs for certain sales and marketing programs, and a $0.6 million decrease in travel costs, both related to our cost cutting measures in the second half of fiscal 2009.

     We believe continued investments in our sales and marketing organizational infrastructure and related marketing programs are critical to the success of our strategy of expanding our customer base and enhancing relationships with our existing customers.

     General and Administrative. General and administrative expenses consist primarily of compensation and related employee benefit costs for executive, finance, accounting, human resources, legal and information technology personnel. Non-compensation components of general and administrative expenses include accounting, legal and other professional fees, facilities expenses and other corporate expenses. General and administrative expenses increased to $34.2 million for fiscal 2010 from $32.6 million for fiscal 2009.

The increase in general and administrative expenses was due primarily to a $1.9 million increase in stock-based compensation, including $0.6 million related to stock-based awards issued to employees that joined QLogic in connection with the acquisition of NetXen.

     General and administrative expenses decreased to $32.6 million for fiscal 2009 from $34.0 million for fiscal 2008. The decrease in general and administrative expenses was due primarily to a $2.8 million decrease in stock-based compensation, partially offset by a $1.6 million increase in cash compensation and related benefit costs due to increased headcount.

     Special Charges. During fiscal 2010, we recorded special charges totaling $5.2 million related to the consolidation of facilities and workforce reductions. The special charges consisted primarily of $3.1 million of exit costs related to facilities under non-cancellable leases that we ceased using during fiscal 2010 and $1.5 million of exit costs associated with severance benefits for involuntarily-terminated employees.

     During fiscal 2009, we implemented a workforce reduction initiative, primarily in response to the macroeconomic environment, and recorded special charges totaling $4.1 million. The special charges consisted primarily of $3.9 million of exit costs associated with severance benefits for the affected employees and costs related to a facility under a non-cancelable lease that we ceased using during fiscal 2009.

     During fiscal 2008, we recorded special charges totaling $5.3 million related to workforce reductions and the consolidation and elimination of certain activities, principally related to certain engineering functions. The special charges consisted of $5.0 million for exit costs and $0.3 million for asset impairments. The exit costs include the costs associated with workforce reductions, the cancellation of a contract and the consolidation of certain facilities.

     The total unpaid exit costs as of March 28, 2010 of $4.2 million are expected to be paid over the terms of the related agreements through fiscal 2018, including $1.9 million in fiscal 2011.

Interest and Other Income, Net

     Components of our interest and other income, net, are as follows:

		2010				2009				2008
		(In millions)
Interest income		$	5.4			$	11.3			$	20.6
Net gains on investment securities			5.0				7.1				0.6
Impairment of investment securities			—				(16.4	)			(6.9	)
Other			0.2				0.1				(0.3	)
		$	10.6			$	2.1			$	14.0

     Interest income is earned on our portfolio of investment securities and cash equivalents. The decrease in interest income for fiscal 2010 from fiscal 2009 was primarily due to a decline in interest rates. The decrease in interest income for fiscal 2009 from fiscal 2008 was primarily due to a decrease in the balance of our investment securities and a decline in interest rates.

     During fiscal 2010, net gains on investment securities were $5.0 million and included $2.7 million of net gains on sales of available-for-sale securities, a $1.9 million gain from distributions of our investments in a money market fund and an enhanced cash fund sponsored by The Reserve (an asset management company), and $0.4 million of net gains on our trading securities.

     During fiscal 2009, net gains on investment securities were $7.1 million and included an $8.1 million gain on recognition of put options and $3.6 million of net gains on sales of available-for-sale securities. These gains were partially offset by a $3.4 million loss upon initial reclassification of the auction rate securities (ARS) to trading securities and a $1.2 million net loss due to subsequent changes in the fair value of trading securities.

     The $8.1 million gain on recognition of put options resulted from an agreement that we entered into with the broker for our ARS that entitles us to sell the related ARS back to the broker for a price equal to the liquidation preference of the ARS plus accrued but unpaid dividends or interest, if any, at any time between June 30, 2010 and July 2, 2012, if the securities are not earlier redeemed or sold.

     We reviewed various factors in determining whether to recognize an impairment charge related to our unrealized losses in available-for-sale securities, including the current financial and credit market environment, the financial condition and near-term prospects of the issuer of the security, the magnitude of the loss compared to the cost of the investment, the length of time the investment has been in a loss position and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery of market value. Based on this analysis, we determined that a portion of the unrealized losses for our portfolio of available-for-sale securities were other-than-temporary and recorded impairment charges of $11.3 million and $6.9 million during fiscal 2009 and 2008, respectively. In addition, during fiscal 2009, we recorded $5.1 million of impairment charges related to our cost basis investments in The Reserve.

Income Taxes

     Our effective income tax rate was 50% in fiscal 2010, 36% in fiscal 2009 and 35% in fiscal 2008. The increase in our effective tax rate in fiscal 2010 is primarily due to a $29.7 million tax charge recorded in fiscal 2010 related to our globalization initiative, partially offset by the favorable impact of (i) higher income generated from our foreign operations, which are taxed at more favorable rates, (ii) an increase in tax benefits related to stock-based awards, (iii) a reduction in our valuation allowance against deferred tax assets related to impairment charges on certain investment securities, and (iv) the resolution of various state and foreign tax matters.

     We implemented a globalization initiative to expand our worldwide footprint beginning in fiscal 2005. As part of this initiative, certain intellectual property and other rights were licensed to one of our international subsidiaries. During the fourth quarter of fiscal 2010, the license agreement was amended which resulted in a fully paid-up license. The $29.7 million tax charge recorded in fiscal 2010 was primarily due to the amendment of this license agreement. As a result of the amendment, we determined that all payment obligations under the license agreement had been satisfied and, accordingly, management expects a significantly lower effective tax rate in fiscal 2011 and subsequent years. We currently believe that our effective tax rate will approximate 20% in fiscal 2011.

     Given the increased global scope of our operations, and the complexity of global tax and transfer pricing rules and regulations, it has become increasingly difficult to estimate earnings within each tax jurisdiction. If actual earnings within each tax jurisdiction differ materially from our estimates, we may not achieve our expected effective tax rate. Additionally, our effective tax rate may be impacted by other items including the tax effects of acquisitions, newly enacted tax legislation, examinations by tax authorities, stock-based compensation, tax legislation related to the expiration or reinstatement of federal research credits and uncertain tax positions.

Liquidity and Capital Resources

     Our combined balances of cash, cash equivalents and investment securities decreased to $375.7 million at March 28, 2010, from $378.3 million at March 29, 2009. We believe that existing cash, cash equivalents, investment securities and expected cash flow from operations will provide sufficient funds to finance our operations for at least the next twelve months. However, it is possible that we may need to supplement our existing sources of liquidity to finance our activities beyond the next twelve months or for the future acquisition of businesses, products or technologies and there can be no assurance that sources of liquidity will be available to us at that time.

     Cash provided by operating activities was $161.8 million for fiscal 2010 and $219.7 million for fiscal 2009. Operating cash flow for fiscal 2010 reflects our net income of $54.9 million, net non-cash charges of $78.0 million and a net decrease in the non-cash components of working capital of $28.9 million. The decrease in the non-cash components of working capital was primarily due to a $21.9 million decrease in inventories and an $11.8 million increase in accrued taxes, partially offset by a $6.0 million decrease in accrued compensation, primarily related to decreased incentive compensation. The decrease in inventories was primarily associated with the completion of a planned contract manufacturer transition in fiscal 2010, which started in fiscal 2009 and resulted in higher inventory levels at the end of fiscal 2009, and higher product shipments during the fourth quarter of fiscal 2010 compared to the prior year. The increase in accrued taxes was primarily due to the timing of expected payment obligations.

     Cash used in investing activities was $42.9 million for fiscal 2010 and consisted of $24.5 million of purchases of property and equipment, $20.4 million of net purchases of available-for-sale securities, and $14.9 million for the acquisition of NetXen (net of cash acquired), partially offset by $11.4 million of proceeds from redemptions of auction rate securities at par value and distributions totaling $5.5 million from our investments in a money market fund and enhanced cash fund sponsored by The Reserve (an asset management company). Cash provided by investing activities for fiscal 2009 was $5.9 million and consisted of distributions totaling $48.9 million related to our investments in the funds sponsored by The Reserve, net sales and maturities of available-for-sale securities of $40.4 million and proceeds from redemptions of auction rate securities at par value of $4.5 million, partially offset by a $57.2 million reclassification of certain cash equivalents to investment securities related to our investments in the funds sponsored by The Reserve and purchases of property and equipment of $30.7 million.

     As our business grows, we expect capital expenditures to increase in the future as we continue to invest in machinery and equipment, more costly engineering and production tools for new technologies, and enhancements to our corporate information technology infrastructure.

     Cash used in financing activities was $132.3 million for fiscal 2010 and consisted of our purchase of $163.4 million of common stock under our stock repurchase program, $2.9 million for minimum tax withholdings paid on behalf of employees for restricted stock units that vested during the period and the repayment of a $0.9 million line of credit assumed in the NetXen acquisition, partially offset by $34.9 million of proceeds from the issuance of common stock and excess tax benefits from stock-based awards. Cash used in financing activities for fiscal 2009 of $181.9 million consisted of our purchase of $205.7 million of common stock under our stock repurchase programs and $2.0 million for minimum tax withholdings paid on behalf of employees for restricted stock units that vested during the period, partially offset by $25.8 million of proceeds from the issuance of common stock and excess tax benefits from stock-based awards.

     As of March 28, 2010, our investment securities included $22.3 million of investments in ARS, the majority of which are rated AA or higher. During late fiscal 2008, the market auctions of many ARS began to fail, including auctions for our ARS. The underlying assets for auction rate debt securities in our portfolio are student loans, substantially all of which are backed by the federal government under the Federal Family Education Loan Program. The underlying assets of our auction rate preferred securities are the respective funds’ investment portfolios.

     In November 2008, we entered into an agreement with the broker for all of the ARS we currently hold, which provides us with certain rights (ARS Rights), in exchange for the release of potential claims and damages against the broker. The ARS Rights entitle us to sell the related ARS back to the broker for a price equal to the liquidation preference of the ARS plus accrued but unpaid dividends or interest, if any, which price is referred to as “par.” The ARS Rights may be exercised by us at any time between June 30, 2010 and July 2, 2012, if the securities are not earlier redeemed or sold. Under the ARS Rights, the broker may, at its discretion, purchase the ARS at any time through July 2, 2012 without prior notice to us and must pay us par value for the ARS within one day of the sale transaction settlement. While we expect to ultimately recover our investments in the ARS at par, we may be unable to liquidate some or all of our ARS should we need or desire to access the funds invested in those securities prior to redemption by the issuer or the exercise of the ARS Rights. There is also a risk that our broker will default on its obligation to purchase the ARS in the event that we exercise the ARS Rights.

     Our investment securities are valued based on quoted market prices or other observable market inputs, except for the ARS, the put options related to ARS, and investments accounted for under the cost method. As of March 28, 2010, the entire $22.3 million portfolio of ARS and the related put options valued at $1.4 million (collectively, 13% of our investment securities portfolio) were measured at fair value based primarily on an income approach using estimates of future cash flows. The assumptions used in preparing the discounted cash flow models included estimates for the amount and timing of future interest and principal payments, the collateralization of underlying security investments, the creditworthiness of the issuer and the rate of return required by investors to own these securities in the current environment, including call and liquidity premiums.

     Since fiscal 2003, we have had various stock repurchase programs that authorized the purchase of up to $1.55 billion of our outstanding common stock, including a program approved in November 2008 authorizing the repurchase of up to $300 million of our outstanding common stock. As of March 28, 2010, we had repurchased a total of 92.6 million shares of our common stock under our stock repurchase programs for an aggregate purchase price of $1.45 billion. Pursuant to the existing stock repurchase program, we are authorized to repurchase shares with an aggregate cost of up to $104.4 million as of March 28, 2010.

     We have certain contractual obligations and commitments to make future payments in the form of non-cancelable purchase orders to our suppliers and commitments under operating lease arrangements. A summary of our contractual obligations as of March 28, 2010, and their impact on our cash flows in future fiscal years, is as follows:

		2011				2012				2013				2014				2015				Thereafter				Total
										(In millions)
Operating leases		$	7.6			$	5.3			$	3.7			$	3.7			$	2.9			$	5.9			$	29.1
Non-cancelable purchase obligations			72.4				—				—				—				—				—				72.4
Total		$	80.0			$	5.3			$	3.7			$	3.7			$	2.9			$	5.9			$	101.5

     The amount of unrecognized tax benefits, including related accrued interest and penalties, was $70.6 million at March 28, 2010. We are not able to provide a reasonable estimate of the timing of future tax payments related to these obligations.

Critical Accounting Policies and Estimates

     The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires us to make estimates and judgments that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net revenues and expenses during the reporting period. We base our estimates on historical experience and on various other factors, including the current economic environment, which we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. We believe the accounting policies described below to be our most critical accounting policies. These accounting policies are affected significantly by judgments, assumptions and estimates used in the preparation of the financial statements and actual results could differ materially from the amounts reported based on these policies.

Revenue Recognition

     We recognize revenue from product sales when all of the following fundamental criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the price to the customer is fixed or determinable and (iv) collection of the resulting accounts receivable is reasonably assured.

     For all sales, we use a binding purchase order or a signed agreement as evidence of an arrangement. Delivery occurs when goods are shipped and title and risk of loss transfer to the customer, in accordance with the terms specified in the arrangement with the customer. The customer’s obligation to pay and the payment terms are set at the time of delivery and are not dependent on the subsequent resale of our product. However, certain of our sales are made to distributors under agreements that contain a limited right to return unsold product and price protection provisions. These return rights and price protection provisions limit our ability to reasonably estimate product returns and the final price of the inventory sold to distributors. As a result, the price to the customer is not fixed or determinable at the time products are delivered to distributors. Accordingly, we recognize revenue from these distributors based on the sell-through method using inventory information provided by the distributor. At times, we provide standard incentive programs to our customers. We account for our competitive pricing incentives, which generally reflect front-end price adjustments, as a reduction of revenue at the time of sale, and rebates as a reduction of revenue in the period the related revenue is recorded based on the specific program criteria and historical experience. In addition, we record provisions against revenue and cost of revenue for estimated product returns in the same period that revenue is recognized. These provisions are based on historical experience as well as specifically identified product returns. Royalty and service revenue is recognized when earned and receipt is reasonably assured.

     For those sales that include multiple deliverables, we allocate revenue based on the relative fair values of the individual components. When more than one element, such as hardware and services, are contained in a single arrangement, we allocate revenue between the elements based on each element’s relative fair value, provided that each element meets the criteria for treatment as a separate unit of accounting. An item is considered a separate unit of accounting if it has value to the customer on a standalone basis and there is objective and reliable evidence of the fair value of the undelivered items. Fair value is generally determined based upon the price charged when the element is sold separately. In the absence of fair value for a delivered element, we allocate revenue first to the fair value of the undelivered elements and allocate the residual revenue to the delivered elements. In the absence of fair value for an undelivered element, the arrangement is accounted for as a single unit of accounting, resulting in a deferral of revenue recognition for the delivered elements. Such deferred revenue is recognized over the service period or when all elements have been delivered.

     We sell certain software products and related post-contract customer support (PCS). We recognize revenue from software products when all of the following fundamental criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the price to the customer is fixed or determinable and (iv) collection of the resulting accounts receivable is probable. Revenue is allocated to undelivered elements based upon vendor-specific objective evidence (VSOE) of the fair value of the element. VSOE of the fair value is based upon the price charged when the element is sold separately. Revenue allocated to each element is then recognized when the basic revenue recognition criteria are met for each element. If we are unable to determine VSOE of fair value for an undelivered element, the entire amount of revenue from the arrangement is deferred and recognized over the service period or when all elements have been delivered.

Stock-Based Compensation

     We recognize compensation expense for all stock-based awards made to employees and non-employee directors, including stock options, restricted stock units and stock purchases under our Employee Stock Purchase Plan (the ESPP), based on estimated fair values on the date of grant. Stock-based compensation is recognized for the portion of the award that is ultimately expected to vest. Forfeitures are estimated at the time of grant based on historical trends and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. We recognize stock-based compensation expense on a straight-line basis over the requisite

service period, which is the vesting period for stock options and restricted stock units, and the offering period for the ESPP. The determination of fair value of stock-based awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, our expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors. In estimating expected stock price volatility, we use a combination of both historical volatility, calculated based on the daily closing prices of our common stock over a period equal to the expected term of the option, and implied volatility, utilizing market data of actively traded options on our common stock. We believe that the historical volatility of the price of our common stock over the expected term of the option is a strong indicator of the expected future volatility. We also believe that implied volatility takes into consideration market expectations of how future volatility will differ from historical volatility. Accordingly, we believe a combination of both historical and implied volatility provides the best estimate of the future volatility of the market price of our common stock. Changes in the subjective assumptions can materially affect the estimated fair value of stock-based awards.

Income Taxes

     We utilize the asset and liability method of accounting for income taxes. Income tax positions taken or expected to be taken in a tax return should be recognized in the first reporting period that it is more likely than not the tax position will be sustained upon examination. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. Previously recognized income tax positions that fail to meet the recognition threshold in a subsequent period are derecognized in that period. Differences between actual results and our assumptions, or changes in our assumptions in future periods, are recorded in the period they become known. We record potential accrued interest and penalties related to unrecognized tax benefits in income tax expense.

     Deferred income taxes are recognized for the future tax consequences of temporary differences using enacted statutory tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Temporary differences include the difference between the financial statement carrying amounts and the tax bases of existing assets and liabilities and operating loss and tax credit carryforwards. The effect on deferred taxes of a change in tax rates is recognized in earnings in the period that includes the enactment date.

     A valuation allowance is recorded when it is more likely than not that some or all of a deferred tax asset will not be realized. An adjustment to earnings would occur if we determine that we are able to realize a different amount of our deferred tax assets than currently expected.

     As a multinational corporation, we are subject to complex tax laws and regulations in various jurisdictions. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws themselves are subject to change as a result of changes in fiscal policy, changes in legislation, evolution of regulations and court rulings. Therefore, the actual liability for U.S. or foreign taxes may be materially different from our estimates, which could result in the need to record additional liabilities or potentially to reverse previously recorded tax liabilities. Differences between actual results and our assumptions, or changes in our assumptions in future periods, are recorded in the period they become known.

Investment Securities

     Our investment securities include available-for-sale securities, trading securities and other investment securities and are classified in the consolidated balance sheets based on the nature of the security and the availability for use in current operations.

     Our available-for-sale securities are recorded at fair value, based on quoted market prices or other observable inputs. Unrealized gains and losses, net of related income taxes, on our portfolio of available-for-sale securities are excluded from earnings and reported as a separate component of accumulated other comprehensive income until realized.

     Our trading securities are recorded at fair value with unrealized holding gains and losses included in earnings and reported in interest and other income, net. In the absence of quoted market prices for trading securities, we value these securities based on an income approach using an estimate of future cash flows.

     Our other investment securities are accounted for under the cost method and recorded at the lower of fair value or cost.

     We recognize an impairment charge on our available-for-sale and cost method investments when the decline in the fair value of an investment below its cost basis is judged to be other-than-temporary. If we intend to sell the security or it is more likely than not that

we will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, we would recognize the entire impairment in earnings. If we do not intend to sell the security and it is not more likely than not that we will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary impairment is separated into (a) the amount representing the credit loss and (b) the amount related to all other factors. The amount of the other-than-temporary impairment related to the credit loss is recognized in earnings. The amount of the other-than-temporary impairment related to other factors is recognized in other comprehensive income, net of applicable taxes. Significant judgment is required in determining the fair value of investment securities in inactive markets as well as determining when declines in fair value constitute an other-than-temporary impairment. We consider various factors in determining whether to recognize an impairment charge, including the current financial and credit market environment, the financial condition and near-term prospects of the issuer of the security, the magnitude of the loss compared to the cost of the investment, the length of time the investment has been in a loss position and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery of market value.

     Realized gains or losses are determined on a specific identification basis and reported in interest and other income, net, as incurred.

Inventories

     Inventories are stated at the lower of cost (first-in, first-out) or market. We write down the carrying value of our inventory to estimated net realizable value for estimated excess and obsolete inventory based upon assumptions about future demand and market conditions. These assumptions are based on economic conditions and trends (both current and projected), anticipated customer demand and acceptance of our current products, expected future products and other assumptions. If actual market conditions are less favorable than those projected by management, additional write-downs may be required. Once we write down the carrying value of inventory, a new cost basis is established. Subsequent changes in facts and circumstances do not result in an increase in the newly established cost basis.

Goodwill and Other Intangible Assets

     Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The amounts and useful lives assigned to intangible assets acquired, other than goodwill, impact the amount and timing of future amortization. The amount assigned to in-process research and development is capitalized and accounted for as an indefinite-lived intangible asset until the underlying projects are completed or abandoned.

     Goodwill is not amortized but instead is tested at least annually for impairment, or more frequently when events or changes in circumstances indicate a potential impairment, by comparing the carrying value to the fair value of the reporting unit to which the goodwill is assigned. A two-step test is used to identify the potential impairment and to measure the amount of impairment, if any. The first step is to compare the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit is less than its carrying amount, goodwill is considered impaired and the loss is measured by performing step two. Under step two, the impairment loss is measured by comparing the implied fair value of the reporting unit with the carrying amount of goodwill. We perform the annual test for impairment as of the first day of our fiscal fourth quarter. During the annual goodwill impairment test in fiscal 2010, we completed step one and determined that there was no impairment of goodwill since the fair value (based on quoted market price) of the reporting unit exceeded its carrying value. Based on this impairment test, we believe that we have no at-risk goodwill.

     The initial recording and subsequent evaluation for impairment of goodwill and purchased intangible assets requires the use of significant management judgment regarding the forecasts of future operating results. It is possible that our business plans may change and our estimates used may prove to be inaccurate. If our actual results, or the plans and estimates used in future impairment analyses, are lower than current estimates used, we could incur impairment charges.

Long-Lived Assets

     Long-lived assets, including property and equipment and purchased intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Significant judgment is required in determining whether a potential indicator of impairment of our long-lived assets exists. Recoverability of assets to be held and used is measured by the comparison of the carrying amount of an asset or asset group to future undiscounted net cash flows expected to be generated by the asset or asset group. If such an asset or asset group is considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset or asset group exceeds the fair value of the asset or asset group. Assets to be disposed of are reported at the lower of their carrying amount or fair value less costs to

sell. Estimating future net cash flows and determining proper asset groupings for the purpose of this impairment test requires the use of significant management judgment. If our actual results, or estimates used in future impairment analyses, are lower than our current estimates, we could incur impairment charges.

Recently Issued Accounting Standards Not Yet Effective

     In September 2009, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2009-13, which provides amendments to Accounting Standards Codification (ASC) Topic 605 “Multiple-Deliverable Revenue Arrangements.” ASU No. 2009-13 replaces and significantly changes certain guidance in ASC Topic 605. ASU No. 2009-13 modifies the separation criteria of ASC Subtopic 605-25 by eliminating the criterion for objective and reliable evidence of fair value for the undelivered products or services. Instead, revenue arrangements with multiple deliverables should be divided into separate units of accounting provided the deliverables meet certain criteria. ASU No. 2009-13 eliminates the use of the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables based on their relative selling price. ASU No. 2009-13 provides a hierarchy for estimating the selling price for each of the deliverables. ASU No. 2009-13 is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. We are currently assessing the impact ASU No. 2009-13 will have on our consolidated results of operations or financial position.

     In September 2009, the FASB issued ASU No. 2009-14, “Certain Revenue Arrangements That Include Software Elements.” Pursuant to ASU No. 2009-14, all tangible products containing both software and non-software components that function together to deliver the product’s essential functionality will no longer be within the scope of ASC Subtopic 985-605 and will be required to be accounted for under the guidance in ASU No. 2009-13. ASU No. 2009-14 provides a list of items to consider when determining whether the software and non-software components function together to deliver a product’s essential functionality. ASU No. 2009-14 is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. We are currently assessing the impact ASU No. 2009-14 will have on our consolidated results of operations or financial position.

     In January 2010, the FASB issued ASU No. 2010-06, which provides amendments to ASC Topic 820, “Fair Value Measurements and Disclosures.” ASU No. 2010-06 requires new fair value disclosures and clarifies certain existing disclosure requirements. ASU No. 2010-06 is effective for fiscal periods beginning after December 15, 2010 for the requirement to provide information on purchases, sales, issuances and settlements in the Level 3 rollforward on a gross basis. All other disclosure requirements under ASU No. 2010-06 are effective for interim and annual reporting periods beginning after December 15, 2009. We are currently assessing the impact ASU No. 2010-06 will have on our consolidated financial statements.

Item 7a. Quantitative and Qualitative Disclosures About Market Risk

     Our cash and cash equivalents are not subject to significant interest rate risk due to the short maturities of these instruments. As of March 28, 2010, the carrying value of our cash and cash equivalents approximates fair value.

     We maintain a portfolio of investment securities consisting primarily of debt securities, including government and agency securities, corporate debt obligations, asset and mortgage-backed securities and municipal bonds, the majority of which have remaining terms of three years or less. We are exposed to fluctuations in interest rates as movements in interest rates can result in changes in the market value of our investments in debt securities. However, due to the short-term nature of our investment portfolio we do not believe that we are subject to material interest rate risk.

     In accordance with our investment guidelines, we only invest in instruments with high credit quality ratings and we limit our exposure to any one issuer or type of investment. Our portfolio of investment securities as of March 28, 2010 includes $161.6 million of securities that are classified as available for sale. As of March 28, 2010, we had gross unrealized losses associated with our available-for-sale securities of less than $0.1 million that were determined by management to be temporary in nature.

     Our portfolio of investment securities as of March 28, 2010 also includes $18.0 million of auction rate debt securities and $4.4 million of auction rate preferred securities (collectively, ARS), the majority of which are rated AA or higher, and related put options valued at $1.4 million. These investment securities are accounted for as trading securities. During late fiscal 2008, the market auctions of many ARS began to fail, including auctions for our ARS. The underlying assets for auction rate debt securities in our portfolio are student loans, substantially all of which are backed by the federal government under the Federal Family Education Loan Program. The underlying assets of our auction rate preferred securities are the respective funds’ investment portfolios.

     In November 2008, we entered into an agreement with the broker for all of the ARS we currently hold, which provides us with certain rights (ARS Rights), in exchange for the release of potential claims and damages against the broker. The ARS Rights entitle us to sell the related ARS back to the broker for a price equal to the liquidation preference of the ARS plus accrued but unpaid dividends or interest, if any, which price is referred to as “par.” The ARS Rights may be exercised by us at any time between June 30, 2010 and July 2, 2012, if the securities are not earlier redeemed or sold. Under the ARS Rights, the broker may, at its discretion, purchase the ARS at any time through July 2, 2012 without prior notice to us and must pay us par value for the ARS within one day of the sale transaction settlement. While we expect to ultimately recover our investments in the ARS at par, we may be unable to liquidate some or all of our ARS should we need or desire to access the funds invested in those securities prior to redemption by the issuer or the exercise of the ARS Rights. There is also a risk that our broker will default on its obligation to purchase the ARS in the event that we exercise the ARS Rights.

     Based on our existing cash, cash equivalents and investment securities, as well as our expected cash flows from operating activities, we do not anticipate that the potential lack of liquidity of our ARS in the near-term will affect our ability to execute our current business plan.

     We do not use derivative financial instruments.

Item 8. Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders
QLogic Corporation:

     We have audited the accompanying consolidated balance sheets of QLogic Corporation and subsidiaries as of March 28, 2010 and March 29, 2009, and the related consolidated statements of income, stockholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended March 28, 2010. In connection with our audits of the consolidated financial statements, we also have audited the financial statement schedule of valuation and qualifying accounts as listed in the index under Item 15(a)(2). These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

     We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of QLogic Corporation and subsidiaries as of March 28, 2010 and March 29, 2009, and the results of their operations and their cash flows for each of the years in the three-year period ended March 28, 2010, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

     We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), QLogic Corporation’s internal control over financial reporting as of March 28, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated May 20, 2010, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders
QLogic Corporation:

     We have audited QLogic Corporation’s internal control over financial reporting as of March 28, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). QLogic Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

     We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

     A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

     Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

     In our opinion, QLogic Corporation maintained, in all material respects, effective internal control over financial reporting as of March 28, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

     We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of QLogic Corporation and subsidiaries as of March 28, 2010 and March 29, 2009, and the related consolidated statements of income, stockholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended March 28, 2010, and our report dated May 20, 2010, expressed an unqualified opinion on those consolidated financial statements.
