ISO/IEC 14776-331:2002 PDF

This part of ISO/IEC 14776 defines the command set extensions to facilitate operation of SCSI stream devices. This standard in conjunction with ANSI INCITS 351-2001 fully specifies the standard command set for the SCSI stream device class.

The objective of this standard (SSC) is to provide the following:

• permit an application client to communicate over a SCSI service delivery subsystem, with a logical unit that declares itself to be a sequential access device or printer device in the device type field of the INQUIRY command response data;
• define commands unique to each type of SCSI stream device;
• define commands to manage the operation of SCSI stream devices; and
• define the differences between the types of SCSI stream devices.

Figure 1 shows the general structure of SCSI standards. The figure is not intended to imply a relationship such as a hierarchy, protocol stack or system architecture.
