CUsing SMI-S
This appendix provides information for network administrators who are managing the storage system from a storage
management application through the Storage Management Initiative Specification (SMI-S). SMI-S is a Storage
Networking Industry Association (SNIA) standard that enables interoperable management for storage networks and
storage devices.
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:
• xmlCIM: defines XML elements, conforming to DTD, which can be used to represent CIM classes and instances
• CIM Operations over HTTP: defines a mapping of CIM operations onto HTTP; 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. UML is used to create a graphical
representation (using boxes and lines) of objects and relationships.
• 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 HTTPS.
SMI-enabled management clients such as HP SIM or HP Storage Essentials can perform storage management tasks
such as monitoring, configuring or event-management. 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 Target Ports subprofile
• SAS Target Ports subprofile
• iSCSI Target Ports subprofile
• Disk Drive Lite profile
• Extent Composition subprofile
• Storage Enclosure profile
• Fan profile
• Power Supply profile
• Sensors profile
• Access Points subprofile
• Location subprofile
