Serial Attached SCSI (SAS) is a point-to-point serial protocol that is used to move data to and from computer storage devices such as hard drives and tape drives. SAS was designed to replace the older parallel SCSI (pronounced "scuzzy") bus technology that first appeared in the mid-1980s. SAS, like its predecessor, uses the standard SCSI command set. SAS offers backwards-compatibility with second-generation SATA drives. SATA 3 Gbit/s drives may be connected to SAS backplanes, but SAS drives may not be connected to SATA backplanes.
The T10 technical committee of the International Committee for Information Technology Standards (INCITS) develops and maintains the SAS protocol; the SCSI Trade Association (SCSITA) promotes the technology.

Famous quotes containing the words serial and/or attached:
“And the serial continues:
Pain, expiation, delight, more pain,
A frieze that lengthens continually, in the lucky way
Friezes do, and no plot is produced,
Nothing you could hang an identifying question on.”
—John Ashbery (b. 1927)
“We saw a pair of moose-horns on the shore, and I asked Joe if a moose had shed them; but he said there was a head attached to them, and I knew that they did not shed their heads more than once in their lives.”
—Henry David Thoreau (1817–1862)
