15.3 About the WBEM Initiative
SMI-S is based on the Web-Based Enterprise Management (WBEM) Initiative, which is defined
by the Distributed Management Task Force (DMTF). WBEM is a set of management and
Internet standard technologies developed to unify the management of distributed computing
environments.
The DMTF has developed a core set of standards that make up WBEM:
■ The Common Information Model (CIM) standard
The CIM standard is the data model for WBEM. CIM provides a conceptual framework for
describing management data for systems, networks, applications and services, and allows
for vendor extensions. SMI-S uses CIM to model those objects and relationships that
comprise a SAN.
■ CIM-XML
CIM-XML is a method of exchanging CIM management data. CIM-XML uses an xmlCIM
payload and HTTP(s) as the transport mechanism.
This protocol is defined by the following specifications:
◆ Specification for the Representation of CIM in XML
Defines a standard for the representation of CIM elements and messages in XML,
written in Document Type Definition (DTD).
◆ CIM Operations over HTTP
Defines a mapping of CIM Messages onto HTTP that allows implementations of CIM to
interoperate in an open, standardized manner. It uses the CIM XML DTD that defines
the XML Schema for CIM objects and messages.
■ WBEM Discovery using Service Location Protocol (SLP)
WBEM Discovery using SLP is a method for applications to identify WBEM-based
management systems.
