QLogic 8100 Series Single Chip CNAs Certified to Work With
      Cisco UCS Virtualized and Cloud Computing Environments

ALISO VIEJO, Calif., March 2, 2010 (GLOBE NEWSWIRE) -- Demonstrating
once again that it is the premier supplier of single-chip based Fibre
Channel over Ethernet (FCoE) converged network adapters (CNAs), QLogic
Corp. (Nasdaq:QLGC) today announced that its industry-leading 8100
Series CNAs have been certified for interoperability for the Cisco
Unified Computing System(TM) platform (UCS). QLogic dual-port 10GbE
converged network adapters are now available to work with the Cisco
UCS, a unified architecture that unites compute, network, storage
access, and virtualization resources in a single energy-efficient
system using industry-standard technologies.

QLogic's award-winning 8100 Series CNAs combines data and storage
networking onto a single, low-profile, energy-efficient design, are
also fully certified for use with Cisco Nexus(R) 5000 Series FCoE
switches, which are commonly deployed with the Cisco Unified Computing
System. The Nexus 5000 Series simplifies data center transformation by
unleashing a high-performance, standards-based, Ethernet fabric that
consolidates separate LAN, SAN, and server cluster network environments
into a single unified fabric.

"Products like the Cisco Unified Computing System, Cisco Nexus 5000
Series and QLogic FCoE CNAs are changing the principles of configuring
server and storage infrastructure," said David Vellante, co-founder and
chief research advocate, Wikibon. "The common practice of configuring
server I/O by application type, where each rack of servers is
customized with I/O and communications specific to a workload is no
longer viable as server utilization hovers under 10 percent and server
heat densities approach the danger zone. The combination of QLogic
CNAs, the Cisco UCS platform, Intel-based Nehalem processors and
virtualization software has the potential to increase server
utilization three to five times over current levels--supporting massive
consolidation and efficiency initiatives within IT organizations."

"By using less equipment, less energy and less space, the Cisco Unified
Computing System is changing the economics of the data center, reducing
capital expenditures by up to 20 percent and operational expenditures
by up to 30 percent," said Soni Jiandani, vice president of marketing,
Server Access Virtualization Business Group for Cisco. "We are working
with industry vendors like QLogic to certify that their solutions are
optimized for the Cisco UCS platform to ease the migration to
virtualized and cloud computing environments."

"Cisco is driving innovation in the data center with the Cisco UCS
platform, a scalable, 'wire-once' solution that can be managed as a
single system whether it has one or more than 300 servers with
thousands of virtual machines," said Amit Vashi, vice president of
marketing, Host Solutions Group, QLogic Corp. "Our converged network
adapters are built on the same battle-proven QLogic Fibre Channel stack
that has over seven million ports deployed and are fully optimized for
virtualized environments such as this industry standard platform."
