Definition: SAS
(1) See also SSA.
(2) (SAS Institute Inc., Cary, NC, www.sas.com) A software company that specializes in business analytics, founded in 1976. See SAS System.
(3) (Serial Attached SCSI) A standard hardware interface for hard disks in drive arrays, servers and high-end workstations. SAS is a serial version of the parallel SCSI hardware interface and was ratified by ANSI in 2003 as the next-generation SCSI technology.
SAS is a point-to-point architecture that uses a disk controller (host bus adapter) with four or more full-duplex channels that operate simultaneously. Each channel (each SAS port) transfers data at 3 or 6 Gbps in each direction.
SAS Transport Protocols
For SAS drives only, the Serial SCSI Protocol (SSP) is used. SAS also supports SATA drives, in which case the Serial ATA Tunneling Protocol (STP) is employed, and expanders (see below) use the Serial Management Protocol (SMP). See SATA, SCSI and hard disk.
Massive Scalability
SAS channels (ports) can connect to a single drive or to an expander that connects up to 128 drives (or host bus adapters). A Fanout Expander can connect Edge Expanders, and one system can support 16,256 drives.
Dual Ports for Fault Tolerance
SAS drives use the same form factor as Serial ATA (SATA) for the cable connector, but add a second port for connection to two controllers or expanders for fault tolerance.
