ALISO VIEJO, Calif., Feb. 28, 2007 (PRIME NEWSWIRE) -- QLogic Corp. (Nasdaq:QLGC), a leading provider of iSCSI HBAs, today announced the availability of the industry's first iSCSI HBA functionality to be accepted into the "upstream" Linux kernel. Developed by the Linux community, the upstream Linux kernel is the central core of popular Linux packages including Debian, Red Hat, SuSE, Slackware and Yellowdog. The company's collaboration with the Linux community and the acceptance of the QLogic SANblade(r) 4000 Series functionality into the Linux kernel means that for the first time Linux system administrators can easily deploy fully tested and supported iSCSI networks -- right out of the box.

"Now that iSCSI technology has matured, and the Linux community has accepted it into the kernel, the way is paved for accelerated deployment of the technology," said Amit Vashi, senior director of marketing, QLogic Computer Systems Group. "Today anyone that downloads a kernel will have immediate access to iSCSI connectivity and upcoming distributions will have iSCSI connectivity included on their respective CDs."

QLogic Makes Extensive Architectural Improvements to iSCSI

QLogic worked with the Linux community to enhance the iSCSI transport (user as well as kernel mode) to incorporate iSCSI offload HBA support into the Linux kernel within the open iSCSI model. This includes definition of how iSCSI offload HBAs appear, target discovery, creation and management of offloaded iSCSI sessions, and provisions for coherent use of open iSCSI and HBA-specific device management. These changes benefit not only QLogic customers, but other iSCSI HBA vendors and users of software initiators who can now seamlessly manage iSCSI via the new framework. QLogic plans to continue its work with the Linux community to further enhance iSCSI functionality in the Linux kernel.

QLogic iSCSI Advantages

Unique hardware based iSCSI and TCP/IP offload architecture of QLogic SANblade 4000 Series iSCSI HBAs offer high performance, low CPU utilization, broad OS and platform support as well as boot from SAN capability.
