In computing, Serial Attached SCSI (SAS) is a point-to-point serial protocol that moves data to and from computer-storage devices such as hard disk drives, solid-state drives and tape drives. SAS replaces the older Parallel SCSI (Parallel Small Computer System Interface, usually pronounced "scuzzy" [ 3 ] [ 4 ] ) bus technology that first ...
Recent physical versions of SCSI—Serial Attached SCSI (SAS), SCSI-over-Fibre Channel Protocol (FCP), and USB Attached SCSI (UAS)—break from the traditional parallel SCSI bus and perform data transfer via serial communications using point-to-point links. Although much of the SCSI documentation talks about the parallel interface ...
The introduction of Serial Attached SCSI (SAS) as the most recent evolution of SCSI required redefining the related standard for enclosure management, called SCSI Enclosure Services. SES-2, or SCSI Enclosure Management 2 first revision, was introduced in 2002 and is now at revision 20.

SAS (Serial Attached SCSI) is the interface architecture used to transmit data from the storage controllers to the disk drives in the Adaptable Modular Storage 2000 family. The SAS interface is a full duplex, point-to-point architecture with up to 9600 MB/sec of total system bandwidth and up to 32 links available for concurrent I/O activity.
This overall approach is called SCSI attached enclosure services: The host computer communicates with the disks in the enclosure via a Serial SCSI interface (which may be either FC-AL or SAS). One of the disk devices located in the enclosure is set up to allow SCSI Enclosure Services (SES) communication through a LUN. The disk-drive then ...
A SCSI connector (/ ˈ s k ʌ z i / SKUZ-ee) is used to connect computer parts that communicate with each other via the SCSI standard. Generally, two connectors, designated male and female, plug together to form a connection which allows two components, such as a computer and a disk drive, to communicate with each other.
