- Storage Management Initiative - Specification
SMI-S, or the Storage Management Initiative - Specification, is a storage standard developed and maintained by the
Storage Networking Industry Association(SNIA). It has also been ratified as ANSIstandard [http://webstore.ansi.org/ansidocstore/product.asp?sku=ANSI+INCITS+388-2004 ANSI INCITS 388-2004] . SMI-S is based upon the Common Information Model and the Web-Based Enterprise Managementstandards defined by the Distributed Management Task Force, Management via TCP/IP.
The main objective of SMI-S is to enable broad interoperability among heterogeneous storage vendor systems. The current version is SMI-S V1.2.1. Over 280 products from 18 SNIA Member companies are certified as conformant to SMI-S 1.2.1.

DMTFmanagement profiles for storage systems. The complete SMI Specification is categorised in profiles and sub-profiles. A profile describes the behavioral aspects of an autonomous, self-contained management domain. SMI-S includes profiles for Arrays, Switches, Storage Virtualizer, Volume Management and many other domains. In DMTF parlance, a provider is an implementation for a specific profile. A sub-profile describes part of the domain, which can be common part in many profiles.
At a very basic level, SMI-S entities are divided into two categories:
* Clients are management software applications that can reside virtually anywhere within a network provided they have a physical link (either within the data path or outside the data path) to providers.
* Servers are the devices under management within the storage fabric.
Clients can be host-based management applications (e.g., storage resource management, or SRM), enterprise management applications, or SAN appliance-based management applications (e.g., virtualization engines). Servers can be disk arrays, host bus adapters, switches, tape drives, etc.
2000- A collection of computer data storage industry leaders led by Roger Reich begun building an interoperable management backbone for storage and storage networks (code named [http://www.wbemsolutions.com/tutorials/snia/SMI/Technical/smis-history.html Bluefin] ) in a small industry consortia sponsored by VERITAS software called the Partner Development Process.
2002— Blufin was donated by the consortia to the Storage Networking Industry Association (SNIA) and was later renamed to Storage Management Initiative - Specification or SMI-S. SMI-S 1.0 publicly announced by the SNIA.
2003— The Storage Management Initiative led by Roger Reich launched formal industry wide specification development, interoperability testing and demonstrations programs, as well as conformance testingsystems and certifications.
2004— SMI-S 1.0.2 becomes an ANSI standard. Starts the initial development of SMIS 1.1.0.
2005— SMI-S 1.0.2 submitted to ISO. Releases SMI-S 1.1.0.
