HP Systems Insight Manager 5.2 Update 2 Technical Reference Guide

WBEM
Web-Based Enterprise Management (WBEM) is one of the newest management protocols. This protocol
leverages the industry-standard Common Information Model (CIM) as defined by the DMTF. HP SIM can
communicate to systems directly using the WBEM protocol or to the Windows WMI systems using the WMI
Mapper Proxy. HP SIM uses WBEM to communicate with storage system SMI-S WBEM providers . HP has
been leading this effort through its association with the WBEM initiative. WBEM is an initiative supported
by HP, Microsoft, Intel, BMC, Cisco, and 120 other platform, operating system, and application software
suppliers.
When WBEM is enabled, the management console can obtain information from any system that supports
WBEM. For WBEM to work, the correct user name and password must be provided for the given system.
WBEM enables a larger set of server and storage manageability data to be collected and displayed on the
System Page and in reports. The presence of WBEM enables the Properties pages and enables WBEM
indications (events) to be displayed in event collections. Without HTTP enabled, HP SIM will not discover
any web-based features on a system.
NOTE: HP SIM supports WBEM over HTTPS to ensure user supplied WBEM name and password pairs
are protected.
NOTE: OpenWBEM is not supported.

Protocol functionality
The following table displays descriptions of management protocols displayed under Management Protocols
on the System Page which displays protocols that have responded when attempting to identify the system.
NOTE: The Central Management Server (CMS) initiates the requests for all protocols except events.

System identification, inventory, eventsA common definition of management
information for systems, networks,
applications, and services.

System identification, inventory data, eventsDMI is an RPC-based protocol. To operate,
DMI requires opening a number of ports
through a firewall; therefore, DMI is not
recommended for use through firewalls. It
is largely being replaced by WBEM.
Note: DMI is only used for non-HP systems
running Windows NT and for versions of
HP-UX prior to 11.0. WMI and WBEM are
used for more recent versions.
