QLogic 2500 Series 8Gb Fibre Channel Adapters Added to Sun Microsystems Storage Portfolio

LAS VEGAS, Sept. 15, 2008 (GLOBE NEWSWIRE) -- VMworld -- QLogic Corp. (Nasdaq:QLGC), a leading supplier of high performance network infrastructure solutions, today announced that Sun Microsystems is now offering Sun-branded 8Gb Fibre Channel host bus adapters (HBAs), based on QLogic(r) technology. Available to customers as Sun StorageTek single and dual-port 8Gb Fibre Channel adapters, these innovative products double the performance of previous generation Fibre Channel adapters in Windows, Linux and Solaris OS environments, reduce disk-to-disk replication times, and significantly shorten data backups at low power levels.

"This latest generation of Sun-branded host bus adapters is optimized to provide advanced virtualization features and the highest performance while consuming minimal power," said Amit Vashi, vice president of marketing, QLogic Host Solutions Group. "QLogic is pleased to be able to offer immediate access to improved storage performance."

"These QLogic Fibre Channel adapters provide investment protection to existing SAN deployments and exceptional reliability. New advanced features such as virtualization and low power consumption allow customers to take advantage of greater performance and cost savings through low power consumption," said Gautam Chanda, group manager, networking storage business, Sun Microsystems.

QLogic 2500 Series Adapters -- Transforming Server Connectivity into Competitive Advantage

The QLogic 2500 Series is a family of 8Gb Fibre Channel-to-PCIe Gen2 adapters that are designed for next generation virtualized data centers with powerful multi-processor, multi-core servers. QLogic 2500 Series adapters are optimized for virtualization, power, RAS (reliability, availability, serviceability), security and management to transform server connectivity into competitive advantage. The 2500 Series provides complete investment protection by maintaining backward compatibility with previous Fibre Channel network and PCIe host bus speeds, and are set apart from all other 8Gb Fibre Channel adapters thanks to two breakthrough innovations under the QLogic Star Power Green Initiative -- Dynamic Power Management and Cool HBA technologies. Dynamic power management is the unique ability of the QLogic 2500 to sense the type of PCI Express bus that is present and consume only the amount of power necessary to run at full speed. QLogic Cool HBA technology is the ability of QLogic products like 2500 Fibre Channel adapters to operate without any air flow, unlike competitive products which require fans to be cool.
