Serial Attached SCSI

What Does Serial Attached SCSI Mean?

Serial attached SCSI (SAS) is a type of serial transmission protocol put into hardware components, many of which are part of larger or more distributed systems. This technology is largely used in connecting data storage devices.


Techopedia Explains Serial Attached SCSI

The idea of serial attached SCSI progressed from the dominant method of parallel SCSI over the years. While serial SCSI was initially somewhat slower, advances have meant that SAS has become an efficient way to manage data transmissions – benefits include lack of termination issues and the elimination of clock skew, as well as a high general transfer speed. In fact, SAS is also seen to be faster than SATA systems.

It is a point-to-point architecture where each device has a dedicated link to the initiator. This provides the benefits in terms of speed and efficiency.
