Information Technology – SCSI Object-Based Storage Device Commands - 2 (OSD-2)

active, Most Current
Organization: ANSI
Publication Date: 15 March 2011
Status: active
Page Count: 346
scope:

This standard defines the command set extensions to control operation of Object-Based Storage devices. The clause(s) of this standard pertaining to the SCSI Object-Based Storage Device class, implemented in conjunction with the applicable clauses of the ISO/IEC 14776-453 SCSI Primary Commands -4 (SPC-4), specify the standard command set for SCSI Object-Based Storage devices.

The objective of this standard is to provide the following:

a) Permit an application client to communicate with a logical unit that declares itself to be an Object-Based Storage device in the PERIPHERAL DEVICE TYPE field of the INQUIRY command response data over a SCSI service delivery subsystem;

b) Enable construction of a shared storage processor cluster with equipment and software from many different vendors;

c) Define commands unique to the type of SCSI Object-Based Storage devices; and

d) Define commands to manage the operation of SCSI Object-Based Storage devices.

The set of SCSI standards specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This standard is a functional description. Conforming implementations may employ any design technique that does not violate interoperability.

Figure 1 shows the relationship of this standard to the other standards and related projects in the SCSI family of standards as of the publication of this standard.

Figure 1 is intended to show the general relationship of the documents to one another. Figure 1 is not intended to imply a relationship such as a hierarchy, protocol stack, or system architecture. It indicates the applicability of a standard to the implementation of a given transport.

The term SCSI is used to refer to the family of standards described in this clause.

The following features from previous standards have been made obsolete in this standard:

a) The ROOT bit in the LIST command parameter data;

b) The COLTN bit in the LIST COLLECTION command parameter data;

c) All discussion of linked commands; and

d) Since the CDB format was changed globally, all service action coded value assignments from OSD were made obsolete in this standard and new coded values were assigned.
