Device Manager and CIM/WBEM
Device Manager supports WBEM defined by the standards-setting organization
DMTF. WBEM is a standard proposed by the DMTF for managing networked
devices, including hosts and storage subsystems, over the Internet. WBEM
enables you to share data about devices in different environments (such as
environments with different vendors, operating systems, or protocols) without
considering the differences. WBEM is based on CIM, an object-oriented
information model.
CIM, defined by DMTF, is a standardized approach for managing systems in
network environments. CIM provides a framework for expressing the data to
be managed. Applying CIM to storage subsystems enables you to use
standardized methods to manage the configuration and status of storage
subsystems in networks.
The CIM models provided by Device Manager conform to the SMI-S
specifications (SNIA-CTP) endorsed by SNIA. The CIM models of the Device
Manager server are defined in MOF (Managed Object Format) files provided by
Device Manager.
CIM clients can access Device Manager by using the CIM XML/HTTP interface
defined by WBEM.
