COSTA MESA, Calif.--(BUSINESS WIRE)--April 22, 2003

Collaboration to Accelerate Development of Fibre Channel and

IP Storage ASICs and Host Bus Adapters

Emulex Corporation (NYSE:ELX), the world's leading supplier of storage networking host bus adapters (HBAs), announced today that it will work closely with Intel Corp. to accelerate Emulex's development of interoperable PCI Express ASICs and host bus adapters for its Fibre Channel and Internet protocol (IP) product families.

As part of its work with Intel, Emulex will utilize Intel's Register Transfer Language (RTL), a PCI Express building block which provides Emulex with a significant advantage in its delivery of time-to-market products. Use of Intel RTL is expected to enable Emulex HBAs and ASICs to be interoperable with Intel PCI Express enterprise products.

PCI Express technology is a next step in the evolution of I/O architecture that features high-speed serial connectivity, enabling scalable server I/O performance and connectivity. PCI Express is software compatible with today's industry standard PCI-X servers, enabling customers to seamlessly migrate to the new architecture while leveraging existing investments in SAN connectivity and management solutions. With specifications now complete, Emulex is focused on delivery of PCI Express-enabled solutions, with availability as early as 2004 in line with expected Intel PCI Express chipset availability.

"Emulex is committed to delivering world-class technology with time-to-market leadership. Working closely with Intel provides Emulex with access to tools and resources that will prove critical to the delivery of time to market PCI Express technology to our mutual OEM customers," said Mike Smith, executive vice president of Worldwide Marketing at Emulex. "PCI Express can provide substantial benefits to servers that utilize Emulex's market leading HBAs, while enabling customers to leverage their existing investments in drivers and management solutions."

"The industry is focused on delivery of PCI Express enabled solutions in 2004," said Jim Pappas, director of Initiative Marketing for Intel's Enterprise Platform Group. "Availability of building blocks and enterprise interconnect host bus adapters is critical to a successful launch of PCI Express in the enterprise. We're delighted to see Emulex announce their PCI Express-related plans and look forward to working with them on delivery of time-to-market storage solutions."
