Former AMD, Dell and Sun Executive Tapped to Expand Japan
         Operations for High Performance Networking Leader

ALISO VIEJO, Calif. and TOKYO, March 8, 2010 (GLOBE NEWSWIRE) -- QLogic
Corp. (Nasdaq:QLGC) today announced the appointment of Minoru Yasuda to
general manager, QLogic Japan. Set to expand the company's operations
and market share in Japan, Yasuda brings to QLogic a longstanding track
record of developing highly successful sales and marketing strategies
in Japan for technology leaders such as AMD (NYSE:AMD), Dell
(Nasdaq:DELL) and Sun (Nasdaq:JAVA).

Yasuda will be responsible for building a platform for growth in Japan,
amplifying the company's sales focus with Tier One server and storage
OEMs and pushing the company further into Fibre Channel switching and
InfiniBand solutions for high performance computing applications.
Yasuda will report to Martin Darling, QLogic vice president of Asia
Pacific and Japan Sales.

"QLogic has impeccable high performance networking technology and one
of the broadest portfolios in the industry," said Yasuda. "I look
forward to building the QLogic brand in Japan, and hope to duplicate
the success the company has enjoyed in the United States and other
regions."

"With Japan ranked by IDC as the second largest storage market after
the U.S., the time for QLogic to strengthen its presence there and
capitalize on these opportunities is now," said Darling. "In addition
to expanding our Fibre Channel and InfiniBand business, we expect
customers in large cities such as Tokyo to address city power
restrictions by deploying VMware, Nehalem-based servers and QLogic FCoE
networking solutions with significantly lower power consumption
characteristics."

Yasuda's career spans a multitude of technology sales and management
roles over a period of 24 years. Most recently he served as general
manager for Sun Microsystems x86 System Sales in Japan where he
successfully managed a strategic team and worked with channel partners
to greatly expand the company's share in x86 servers. Prior to Sun,
Yasuda was at AMD Japan, where he served as regional sales director and
headed distribution sales, which accounted for material contributions
to revenue. As regional sales manager at Dell Japan, Yasuda succeeded
in driving revenue growth by 20 percent on a year-over-year basis.
