What Does Common Command Set Mean?

The Common Command Set (CCS) is a set of additional standards made for the Small Computer System Interface (SCSI) in order to increase its market acceptance. It was made to ensure that SCSI devices became vendor-independent and ensure compatibility between different products by not deviating from the SCSI draft by adding or revising functions but through enforcement of those functions.

Techopedia Explains Common Command Set

The Common Command Set for direct-access devices were drafted and proposed as a set of protocols that promote the interoperability of different SCSI devices regardless of vendor; as long as the vendor has adhered to the implementation of the SCSI standard and the CCS, devices should be compatible.

The CCS does not substantially deviate from the proposed standard or even preclude or negate the use and creation of additional commands, and it does not create an entirely new standard. The CCS simply selects and enforces a universally common implementation of the draft SCSI standard. It also defines additional but optional functions which are not found on the original standard.

Sample commands include:

  • REQUEST SENSE
  • FORMAT UNIT
  • INQUIRY
