Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of document should be noted (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Details
of any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents) or the IEC list of patent
declarations received (see http://patents.iec.ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the World
Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT),
see www.iso.org/iso/foreword.html.
This document was prepared by SNIA (as Storage Management Technical Specification, Part 5
Filesystems, Version 1.8.0, Revision 5) and drafted in accordance with its editorial rules. It was adopted,
under the JTC 1 PAS procedure, by Joint Technical Committee ISO/IEC JTC 1, Information technology.
This second edition cancels and replaces the first edition (ISO/IEC 24775-5:2014), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— USAGE text was revised to address code (now included in the front matter for all SNIA specifications)
— All recipes and their references were deleted.
— Instances of subprofile were changed to profile. In the annex, instances of subprofile were changed
to component profile (TSG meeting voice vote).
— Profile versions and related text were updated. (TSG meeting voice vote).
— Indications have been replaced by DMTF Indications, and all affected clauses updated. (TSG meeting
voice vote).
— Instances of Experimental within profiles already labeled as Experimental were removed to avoid
confusion and redundancy. (Editorial change)
— CIM/XML was changed to CIM-XML (Response to ballot comments).

1 INTENDED AUDIENCE
2 This document is intended for use by individuals and companies engaged in developing, deploying, and
3 promoting interoperable multi-vendor SANs through the Storage Networking Industry Association (SNIA)
4 organization.
5 CHANGES TO THE SPECIFICATION
6 Each publication of this specification is uniquely identified by a three-level identifier, comprised of a
7 version number, a release number and an update number. The current identifier for this specification is
8 version 1.8.0. Future publications of this specification are subject to specific constraints on the scope of
9 change that is permissible from one publication to the next and the degree of interoperability and
10 backward compatibility that should be assumed between products designed to different publications of
this standard. The SNIA has defined three levels of change to a specification:
• Major Revision: A major revision of the specification represents a substantial change to the underlying scope
or architecture of the SMI-S API. A major revision results in an increase in the version number of the version
identifier (e.g., from version 1.x.x to version 2.x.x). There is no assurance of interoperability or backward
compatibility between releases with different version numbers.
• Minor Revision: A minor revision of the specification represents a technical change to existing content or an
adjustment to the scope of the SMI-S API. A minor revision results in an increase in the release number of
the specification’s identifier (e.g., from x.1.x to x.2.x). Minor revisions with the same version number preserve
interoperability and backward compatibility.
• Update: An update to the specification is limited to minor corrections or clarifications of existing specification
content. An update will result in an increase in the third component of the release identifier (e.g., from x.x.1 to
x.x.2). Updates with the same version and minor release levels preserve interoperability and backward
compatibility.
TYPOGRAPHICAL CONVENTIONS
Maturity Level
In addition to informative and normative content, this specification includes guidance about the maturity
of emerging material that has completed a rigorous design review but has limited implementation in
commercial products. This material is clearly delineated as described in the following sections. The
typographical convention is intended to provide a sense of the maturity of the affected material, without
29 altering its normative content.
