ISO/IEC 14776-415:2019

ISO/IEC 14776-415:2019 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 Small Computer System Interface (SCSI) specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This document is a functional description. Conforming implementations employ any design technique that does not violate interoperability.<br /> The following concepts from previous versions of the SAM standard are made obsolete by this version:<br /> a) support for the SPI-5 SCSI transport protocol;<br /> b) Contingent Allegiance;<br /> c) the TARGET RESET task management function;<br /> d) basic task management model;<br /> e) untagged tasks; and<br /> f) linked command function.
