QLogic Ships 500,000th Blade Server HBA Port

Milestone Underscores the Pervasive Deployment of SANs Embedded in Blade Servers


ALISO VIEJO, Calif., Sept. 15, 2005 (PRIMEZONE) -- QLogic(r) Corp. (Nasdaq:QLGC), the leader in Fibre Channel host bus adapters (HBAs), today announced the company shipped its 500,000th blade server HBA port. This milestone, along with the recently announced achievement of shipping 20,000 blade server switches, underscores the explosive growth of blade servers and the pervasive deployment of QLogic SANs embedded in blade servers.

"Two years ago blade servers were deployed primarily in non-storage-intensive applications such as web caching," said Roger Klein, vice president of marketing for QLogic Computer Systems Group. "Since then, embedded SANs have played a key role in the proliferation of blade servers in hundreds of storage-intensive application environments."

Reliable SAN Infrastructure for Bladed Servers

Developer of the world's first embedded SAN infrastructure for bladed servers, QLogic is the leading supplier of Fibre Channel embedded switches and HBAs for bladed servers. QLogic HBAs, switches and management controllers provide fast, reliable and scalable storage expansion in an ultra-compact form-factor.

QLogic blade server HBAs are based on the same architecture and technology as QLogic's most popular HBAs which have a field-proven mean-time-before-failure rating of 1.7 million hours -- 100 percent greater than the primary competitor. Reliable QLogic HBAs are backed by a warranty of up to five years -- the best in the industry. That's why according to Dell'Oro, Gartner and IDC, QLogic ranked number one in market share for Fibre Channel HBA ports shipped and Fibre Channel HBA revenue in 2004.
