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 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.
The key SMI-S components are:
• Web-based Enterprise Management (WBEM). A set of management and internet standard technologies developed to unify the
management of enterprise computing environments. WBEM includes the following specifications:
○ CIM XML: defines XML elements, conforming to DTD, which can be used to represent CIM classes and instances
○ CIMxml Operations over HTTP/HTTPS: defines a mapping of CIM operations onto HTTP/HTTPS; used as a transport mechanism
• Common Information Model (CIM). The data model for WBEM. Provides a common definition of management information for
systems, networks, applications and services, and allows for 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 MOF.
• Service Location Protocol (SLP). Enables computers and other devices to find services in a local area network without prior
configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks.
Embedded SMI-S array provider
The embedded SMI-S array provider provides an implementation of SMI-S 1.5 using cim-xml over HTTP/HTTPS. The provider supports
the Array and Server profiles with additional (or supporting) subprofiles. The Server profile provides a mechanism to tell the client how to
connect and use the embedded provider. The Array profile has the following supporting profiles and subprofiles:
• Array profile
• Block Services package
• Physical Package package
• Health package
• Multiple Computer System subprofile
• Masking and Mapping profile
• FC Initiator Ports profile
• SAS Initiator Ports profile
• iSCSI Initiator Ports profile
• Disk Drive Lite profile
• Extent Composition subprofile
• Storage Enclosure profile
• Fan profile
• Power Supply profile
• Sensors profile
• Access Points subprofile
• Location subprofile
• Software Inventory subprofile
• Block Server Performance subprofile
• Copy Services subprofile
• Job Control subprofile
• Storage Enclosure subprofile (if expansion enclosures are attached)
• Disk Sparing subprofile
• Object Manager Adapter subprofile
• Thin Provisioning profile
• Pools from Volumes profile
The embedded SMI-S provider supports:
• HTTPS using SSL encryption on the default port 5989, or standard HTTP on the default port 5988. Both ports cannot be enabled at
the same time.
• SLPv2
• CIM Alert and Lifecycle indications
• Microsoft Windows Server 2012 Server Manager and System Center Virtual Machine Manager
