SAS SAS Device Serial-attached SCSI. A serial, point-to-point, enterprise-level device interface that leverages the proven SCSI protocol set. The SAS interface provides improved performance, simplified cabling, smaller connections, lower pin count, and lower power requirements when compared to parallel SCSI. SAS controllers leverage a common electrical and physical connection interface that is compatible with Serial ATA. The SAS controllers support the ANSI Serial Attached SCSI standard, version 1.0. In addition, the controller supports the Serial ATA (SATA) protocol defined by the Serial ATA specification, version 1.0a. Each port on the SAS RAID controller supports SAS and SATA devices. Any device that conforms to the SAS standard and is attached to the SAS bus by a SAS cable. This includes SAS storage adapters (host adapters) and SAS peripherals. 16 Intel® RAID Controller SASWT4I Hardware User's Guide
