Introduction to SMI-S for HP SIM
The Storage Management Initiative Specification (SMI-S) is a Storage Networking Industry
Association (SNIA) standard that enables interoperable management for storage networks and
storage devices. HP SIM uses this standard to discover and manage the storage systems it supports.
About SMI-S
SMI-S replaces multiple disparate managed object models, protocols, and transports with a single
object-oriented model for each type of component in a storage network. The specification was
created by SNIA to standardize storage management solutions. SMI-S enables management
applications (such as HP SIM) to support storage devices from multiple vendors quickly and reliably
because they are no longer proprietary. SMI-S detects and manages storage elements by type,
not by vendor.
Key components
The key SMI-S components include:
• Common Information Model (CIM)
• Web-based Enterprise Management (WBEM)
• Service Location Protocol (SLP)
CIM
CIM , the data model for WBEM, provides a common definition of management information for
systems, networks, applications, and services, and allows vendor extensions. SMI-S is the
interpretation of CIM for storage. It provides a consistent definition and structure of data, using
object-oriented techniques. The standard language used to define elements of CIM is Meta-Object
Facility (MOF). Unified Modeling Language (UML) creates a graphical representation (using boxes
and lines) of objects and relationships.
WBEM
WBEM is a set of management and Internet standard technologies developed to unify the
management of enterprise computing environments. WBEM includes the following specifications:
• xmlCIM: Defines XML elements, conforming to DTD, which can represent CIM classes and
instances
• CIM Operations over HTTP: Defines a mapping of CIM operations onto HTTP; used as a
transport mechanism
SLP
SLP enables computers and other devices to find services in a LAN without prior configuration. SLP
is designed to scale from small, unmanaged networks to large enterprise networks.
Profiles
SMI-S is organized around profiles, which describe objects relevant for a class of storage subsystem.
SMI-S includes profiles for arrays, Fibre Channel HBAs, Fibre Channel switches, and tape libraries.
Other storage devices (for example, NAS heads) are expected to be added in the future. Profiles
are registered with the CIM server and advertised to clients using SLP. HP SIM determines which
profiles it intends to manage, and then uses the CIM model to discover the actual configurations
and capabilities.
