A Dictionary of Storage Networking Terminology

Common Storage Networking-Related Terms and their Definitions

by the Storage Networking Industry Association


The 2008 SNIA Dictionary was underwritten by the generous contributions of EMC, Hitachi, HP, and Sun Microsystems

The 2008 SNIA Dictionary contains the official industry-approved storage terms and definitions. The terms go through a rigorous technical review and approval process by the SNIA Technical Council to assure accuracy. The SNIA Technical Council is a select group of acknowledged industry technical experts elected by the members of the SNIA that guide the SNIA's technical efforts. Their extensive individual technical backgrounds cover all aspects of storage.

The reader should recognize that in this rapidly evolving field, new terminology is constantly being introduced and common usage is shifting. The SNIA regards this dictionary as a living document, to be updated as necessary to reflect a consensus on common usage, and encourages readers to treat it in that spirit. Comments and suggestions for improvement are gratefully accepted at any time, with the understanding that any submission of comments or suggestions contributes them to SNIA; and SNIA will own all rights (including any copyright or intellectual property rights) in them.

Current Dictionary Version: v.2008.1.ENG

Most of the terms in this dictionary have meaning primarily in specific sub-contexts of storage networking, such as SCSI or Storage Systems. Wherever this is true, the primary context(s) for the term are noted between the term itself and its definition. Terms that do not have one or more contexts identified are generally applicable data processing industry terms.

  1. Any definition reproduced must be reproduced in its entirety with no alteration, and,
  2. Any document, printed or electronic, in which material from this glossary (or any portion hereof) is reproduced must acknowledge the SNIA copyright on that material, and must credit the SNIA for granting permission for its reuse.

Other than as explicitly provided above, you may not make any commercial use of this glossary, sell any or all of this glossary, or distribute this glossary to third parties. All rights not explicitly granted above are expressly reserved to SNIA.
