Describes a protocol for the transport of commands and data over High Performance Serial Bus. The transport protocol, Serial Bus Protocol 2 or SBP-2, requires implementations to conform to the requirements of this standard as well as to ISO/IEC 13213: 1994 and permits the exchange of commands, data and status between initiators and targets connected to Serial Bus.
