What is Serial-attached SCSI (SAS)?
Serial-attached SCSI (SAS) is a protocol that provides serial communication for transfer of data to and from computer storage devices. A SAS system consists of an initiator device and a target device with a subsystem that transmits information between them. SAS drives can be hot-plugged and many devices can be connected simultaneously.
SAS is an improved version of Parallel SCSI because it uses serial data transmission (one bit at a time over a single channel) instead of parallel data transmission (multiple data bits at the same time over multiple channels). Compared with Parallel SCSI, Serial-attached SCSI allows cables to be thinner and longer, connectors to be less bulky, and speeds to be higher. SAS is widely used in data centers due to its capability, scalability, and reliability.
