SAS - 위키피디아 정의

Serial Attached SCSI (SAS) is a computer bus technology primarily designed for transfer of data to and from devices like hard drives, CD-ROM drives and so on. SAS is a serial communication protocol for direct attached storage (DAS) devices. It is designed for the corporate and enterprise market as a replacement for parallel SCSI, allowing for much higher speed data transfers than previously available, and is backwards-compatible with SATA drives (SATA drives may be connected to SAS controllers. However, SAS drives may not be connected to SATA controllers). Though SAS uses serial communication instead of the parallel method found in traditional SCSI devices, it still uses SCSI commands for interacting with SAS End devices.
