INCITS 515:2016

The set of Small Computer System Interface (SCSI) standards consists of this standard and the SCSI implementation standards described in 4.2. This standard defines a reference model that specifies common behaviors for SCSI devices, and an abstract structure that is generic to all SCSI I/O system implementations. The set of SCSI standards specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This standard is a functional description. Conforming implementations may employ any design technique that does not violate interoperability. The following concepts from previous versions of this standard are made obsolete by this standard: a) support for the SPI-5 SCSI transport protocol; b) Contingent Allegiance; c) the TARGET RESET task management function; d) basic task management model; e) untagged tasks; and f) linked command function.
