Industry Leaders Join Together in Commitment to 10Gb/4Gb SANs

Agilent, FalconStor, Fujitsu, JNI, Seagate and QLogic to Provide Customers with 10Gb and 4Gb Products to Meet Demands for Performance and Compatibility

ALISO VIEJO, Calif., June 3, 2003,- QLogic Corp. (Nasdaq:QLGC) today announced that several companies- including Agilent Technologies Inc., FalconStor Software, Fujitsu, JNI and Seagate- have joined QLogic in its commitment to develop 10Gb and 4Gb products for SAN customers, following the Fibre Channel Industry Association's (FCIA) vote to extend 4Gb Fibre Channel from an "inside the box" storage device interconnect into switched SAN fabrics. For businesses with growing investments in 1Gb or 2Gb storage networks, 4Gb products from these vendors will double current Fibre Channel performance at about the same price as 2Gb Fibre Channel, while maintaining backward-compatibility with existing networks and storage. 10Gb solutions will deliver five times the bandwidth of current 2Gb products and will be used in applications that stream large amounts of data across a fabric such as inter-switch links, voice and video.

"We are pleased that the FCIA has once again helped prevent industry fragmentation by providing a clear and concise roadmap for Fibre Channel migration as well as providing invaluable market feedback into the Fibre Channel standards community of engineering professionals," said Skip Jones, sitting Chairman of the Fibre Channel Industry Association.

"As the leading provider of fiber-optic transceivers, we are committed to delivering the solutions our customers require," said Tom Fawcett, worldwide marketing manager for Agilent's Fiber Optic Products. "We believe that there will be demand for both 4 Gb/s and 10 Gb/s products and we intend to meet that demand."

"We commend QLogic for taking a leadership role in the development of new, high performance products designed to support the growing requirements of enterprise SAN users," stated Wai Lam, CTO, FalconStor Software, Inc. "The higher bandwidth delivered by 4Gb fabric will enable our customers to fully leverage the advanced storage services offered by IPStor, including ultra-fast, windowless backup and rapid data replication and recovery, while also enabling them to better support larger, more demanding storage area networks."

"Fujitsu believes that Fibre Channel will continue to be a dominant interface for storage area networks. Storage industry leaders must stay competitive with Fibre Channel technology by increasing performance while maintaining a reasonable cost structure," said Mike Chenery, vice president, advanced product engineering. "Fujitsu's hard drive roadmap includes next generation drives with 4Gb Fibre Channel interfaces and we are excited to support QLogic's commitment in enabling subsystems manufactures to build a cost-effective, scalable path toward 4Gb/10Gb storage solutions."

"JNI's customers are asking for performance improvements from their 2Gb Fibre Channel SANs, a seamless migration path to 4Gb and the ability to deploy 10Gb fabrics for their highest performance applications," said Phil Brotherton, vice president of Marketing, JNI. "We are committed to meeting these needs with our next generation of JNI FibreStar HBAs."

"The next-generation of Fibre Channel technology will serve the growing need for high-bandwidth applications such as real-time transactional processing to a large number of clients in the enterprise as well as areas such as high-definition video streaming," said Gordy Lutz, Seagate senior product marketing manager, and member of the Fibre Channel Industry Assocation (FCIA) Board of Directors. "Seagate supports both 4Gb and 10Gb technologies at the fabric level and is working with various companies to ensure interoperability of future storage solutions."

Customer Requirements for 10/4 High Speed Fibre Channel
IT professionals realize that as each day goes by, the users they're tasked to support are driving more transactions, digital photographs, voice files and video files across their networks. It's easy for SAN architects to understand the need for storage networks with 10Gb of bandwidth and beyond.

SAN architects want a cost-effective, backward-compatible migration path while 10Gb Fibre Channel is gradually adopted. They're asking for 4Gb storage systems, fabric switches and HBAs that cost about the same as similar 2Gb products and that are 100 percent compatible with installed 1Gb and 2Gb products.

The Fibre Channel Industry is Responding
Major manufacturers of Fibre Channel components and systems have been developing products based on both 10Gb and 4Gb Fibre Channel standards for quite some time. Storage system, switch and HBA manufacturers are focused on developing systems with 10Gb Fibre Channel interfaces while disk drive and tape drive manufacturers are developing next generation drives with 4Gb Fibre Channel interfaces. Responding to feedback from their customers, companies such as QLogic are extending the availability of cost-effective 4Gb Fibre Channel products from peripherals, to fabric switches and HBAs.
