Phạm vi áp dụng / Scope of standard

This document describes a communication interface between a
channel and I/O control units that utilize the Single-Byte Command
Code Sets (SBCCS) as implemented in a wide range of data processing
systems. It employs information formats and signaling protocols
that provide a uniform means for communicating with various types
of I/O control units, facilitating a high-bandwidth,
high-performance, and long-distance information exchange
environment. The signaling protocols and information exchanges are
defined at a layer (FC-4) to compatibly utilize the link services
and other functions provided by the INCITS Fibre Channel Framing
and Signalling (FC-FS-3) and the INCITS Fibre Channel Link Services
(FC-LS-2) specifications. This FC-4 Upper Level Protocol is
referred to as the Fibre Channel-Single-Byte-4 Command Code Sets
Mapping Protocol (or for brevity, SB-4). FC-SB-4 modifies FC-SB-3
to include optional support for the transport mode of operation
that allows multiple, single- byte I/O commands to be sent to a
control unit in a single Information Unit. Transport-mode
operations utilize device-level protocols similar to those
described in the FC-4 Fibre Channel Protocol (FCP-4)
specification.
