Serial Attached SCSI in HP World Spotlight
Several vendors are using the HP World show here this week as a way of promoting the developing SASor Serial Attached SCSIinterface.ATLANTASeveral vendors are using the HP World show here this week as a way of promoting the developing SASor Serial Attached SCSIinterface. Maxtor Corp. is showing off its 3.5-inch disk drive, and Seagate Technology Inc. is demonstrating a 2.5-inch hard drive. Meanwhile, Adaptec Inc. is debuting a prototype of a SAS chip that can run at both 3 and 6 gigabits per second. All the demonstrations are designed to highlight SAS, an upcoming interface that some companies believe eventually will replace current parallel SCSI interfaces, resulting in more drives being able to be packaged together for greater capacity, as well as faster performance. Officials with the companies said they expect the first commercial products to hit the market next year.
Like Serial ATA drives, SAS connections link components within or between servers with cables thinner than those used in parallel SCSI.
