HP Systems Insight Manager - Manual (Page 187)

Without HTTPS enabled, HP SIM does not discover any WBEM-based features on a system. Support
for non-HP systems has been expanded starting with HP SIM 6.0.
NOTE: HP SIM supports WBEM over HTTPS to ensure user supplied WBEM name and password
pairs are protected.
NOTE: OpenWBEM is not supported.
Remote Method Invocation (RMI)
Java RMI is used within the CMS only for inter-process communication.
Remote Wake-Up
Remote Wake-Up refers to the ability to remotely turn on a system that is in a soft-off power state.
Systems that support the Advanced Configuration and Power Interface (ACPI) should be awakened
transparently by any network activity to the system. Alternatively, a system might support the Magic
Packet technology. When a system is turned off, the Magic Packet — capable network interface
card (NIC) is still powered on and monitoring traffic. The system will be powered on, if it receives
the Magic Packet targeting it.
Internet Control Message Protocol (ICMP)
ICMP is used during automatic system discovery and prior to other requests to a system to ensure
the system is responding. An ICMP echo request, also known as a ping, is sent to the system's IP
address. Receipt of a proper reply indicates the system is up and responding.
NOTE: HP SIM can be configured to use TCP as a ping, instead of ICMP, from the Global Protocol
Settings page.
Lightweight Directory Access Protocol (LDAP)
LDAP 3 is used during execution of a Directory Group tool to communicate with the configured
directory server to collect information about systems configured in the directory.
Simple Object Access Protocol (SOAP)
SOAP is used by partner applications to communicate with HP SIM. It is primarily XML over HTTPS.
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 CMS initiates the requests for all protocols except events.
Functionality when enabled Description Management standard
System identification, inventory, events A common definition of management
information for systems, networks,
applications, and services. CIM
System identification A protocol using XML over HTTP to
exchange CIM information; part of the
WBEM suite of standards. CIM-XML
System identification, management tool
launch, agent configuration HTTP is another primary protocol used
to acquire data about managed HTTP and HTTPS
systems during identification. HTTP is
not a secure protocol and can be
easily viewed on the network. The
secure version of HTTP is called HTTPS
and is described later.
