Serial Attached SCSI (SAS) announcements are coming fast and furious, as vendors race to lay claim to being first to market with servers and disk arrays based on the successor to parallel SCSI disk drive technology. In the last few months, we've seen SAS announcements from LSI Logic (host bus adapter) and Broadcom (RAID on Chip, or ROC), as well as a SAS hard disk drive demonstration from Maxtor. In fact, some vendors claim they'll be shipping a full-fledged SAS server as early as next month. A case in point is IBM, which announced with Adaptec last month that it would ship a SAS-based server, the x366, by mid-May. The server will use an Adaptec SAS I/O and RAID controller. Hewlett-Packard has also committed to ship SAS-based ProLiant servers and MSA arrays in May. But realistically, "SAS isn't ready for prime time," says Luca Bert, director of product and program management at LSI Logic's RAID Storage Adapter Division.
