SAS, iSCSI Grab the Spotlight

Serial-attached SCSI (SAS) and iSCSI are about to make the leap from vendor hype to data center reality -- so Roger Cox, research vice president at Gartner Inc., told attendees at this weeks StorageTek user Forum in Washington, D.C. But that sunny view from the dais contrasted with reservations about the technologies on the show floor.

Cox told his audience that iSCSI is now a valid alternative to Fibre Channel for building storage area networks. “An iSCSI SAN resolves SAN interoperability issues. [It is also] less expensive if natively connected,” he explained.

“The only thing that has been holding this back was the number of targets with native iSCSI interfaces. But this is starting to change.”

The analyst predicted that vendors' current focus on low-cost host bus adapters (HBAs) will benefit iSCSI. “You will find some of the same vendors developing iSCSI HBAs. This technology is something that, in the right environment, could save you a lot of money.”

Certainly, a number of vendors are turning their attention to iSCSI at the moment. IBM has already signed a deal to use QLogic iSCSI HBAs in its xSeries family, and, last week, Xyratex officials said several OEMs are loading iSCSI target and initiator software onto its new HS-1235 appliance.
