Information technology — Small Computer System Interface (SCSI) — Part 454: SCSI Primary Commands — 4 (SPC-4) (Adopted ISO/IEC 14776-454:2018, first edition, 2018-04)
ISO/IEC 14776 (all parts) provides for many different types of SCSI devices (e.g., disks, tapes, media changers). This standard defines a device model that is applicable to all SCSI devices. Other command standards expand on the general SCSI device model in ways appropriate to specific types of SCSI devices. ISO/IEC 14776 (all parts) specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This standard is a functional description. Conforming implementations employ any design technique that does not violate interoperability. This standard defines the SCSI commands that are mandatory and optional for all SCSI devices. Support for any feature defined in this standard is optional unless otherwise stated. This standard also defines the SCSI commands that may apply to any device model. The following commands, parameter data, and features defined in previous versions of the SPC standard are made obsolete by this standard
