In development for a couple of years, SMI was created by SNIA members to
facilitate interoperability across disparate storage systems, regardless of
vendor. The standard is largely seen as the saving grace for the storage
networking community, in which IT managers could use the lone SMI
application programming interface (API) to ensure the compatibility of
products from competing companies. Because storage industry experts expect
this to drive the market opportunity to new heights, systems heavies such as
IBM, HP and Cisco Systems embrace it.
The SNIA Technical Work Groups, which have finished their review of the
Storage Management Initiative Specification (SMI-Specification) document,
have begun SMI testing at the SNIA
Technology Center as part of the new Storage Management Forum-
(SM-Forum) sponsored CIM-SAN-2 Developers Demonstration Program.
This implementation and testing cycle, which will last for six months,
enables developers to use the specification to flex management applications
in heterogeneous storage networking environments.
Jerry Duggan, chair of the SM-Forum Interoperability Committee, talked about
the test as though it were a sign “on the road to becoming a recognized
public standard.” He also claimed SNIA plans to deliver a standard
specification by the end of 2003.
The first plugfest, CIM-SAN-1, took place at Fall Storage Networking World
2002. The SM-Forum Developers Program will give the first public
demonstration of CIM-SAN-2 capabilities at Storage Networking World (SNW) in
Scottsdale, Ariz. next month.
SNIA said it has made progress from the first go-around, with new security,
discovery and management functionalities in CIM-SAN-2.
For example, CIM-SAN-2 features: array volume creation for creating logical
volumes in arrays and virtualizers and making them available for hosts;
array LUN masking, a security function that controls visibility of logical
volumes to hosts; array snapshot and mirror control for creating, splitting
synchronizing snapshots and mirrored volumes: and fabric topology and zoning
discovery, which facilitates the discovery of how devices are connected to
switches and their zoning parameters.
John Webster, senior storage analyst and co-founder of the Data Mobility
Group, said CIM-SAN demonstrations will make it possible for users to
install interoperable management solutions based on their specific business
needs and allow them to construct more diverse multi-vendor SANs with
“With strong vendor and end user cooperation and high demand for storage
management interoperability, the SM-Forum has the necessary backing to
achieve its goal to make the SMI-Specification — and what it represents in
terms of delivering standards-based product to the marketplace — a reality
Indeed, firms pledging support for CIM-SAN-2 program include such luminaries
as Brocade, Cisco, EMC, Hitachi Data Systems, HP, IBM, Network Appliance and
