Defines generic requirements, which govern SCSI-3 implementation standards, and implementation requirements that apply to all SCSI-3 devices. Implementation requirements specify behavior in terms of measurable or observable parameters pertaining to an implementation. Generic requirements are transformed to implementation requirements by an implementation standard. This standard contains a reference model for the coordination of standards applicable to SCSI-3 I/O systems and a set of common behavioral requirements that are essential for the development of host software and device firmware that can interoperate with any SCSI-3 interconnect or protocol.
