HP Systems Insight Manager 5.2 Update 2 Technical Reference Guide

Functionality when enabledDescriptionManagement Standard
Provides system reachability (ping) check
during system discovery and before other
operations
ICMP is a required protocol tightly
integrated with IP. ICMP messages are
delivered in IP packets and are used for
out-of-band messages related to network
operation.
HP SIM can use ICMP messages to ping a
managed system. However, some routers
block ICMP messages so HP SIM provides
an alternative ping using TCP. See “Setting
global protocols” for more information.
Internet Control Message Protocol (ICMP)
System identification, inventory and eventsPart of the SNMP specification, the MIB is
a model of the information to be managed
through SNMP. It is equivalent to the
Common Information Model (CIM) defined
by WBEM.
Management Information Base (MIB)
System identification, Inventory and eventsSNMP is widely used for management but
the widely implemented versions 1 and 2
have weak security. While no “set”
operations are used by HP SIM, read
access to system data may be visible on
the network. SNMP is UDP-based;
therefore, in many environments it is not
considered a suitable protocol to pass
through the firewall. Because SNMPv1 has
a simple, clear-text “community,” it
provides a low level of security. However,
SNMP may be suitable for some
environments in which the network used
for managing systems is relatively
controlled.
Simple Network Management Protocol
(SNMP)
Remote tool executionSSH is used for remote command
execution. HP SIM uses SSH to run
commands on managed systems.
Secure Shell (SSH)
Consistent server management across
vendors
A DMTF initiative for common server
management which enables
vendor-independent management
applications.
System Management Architecture for Server
Hardware (SMASH)
System identificationAn SNIA standard for storage management
using WBEM.
Storage Management Interface -
Specification (SMI-S)
Identification, inventory, and eventsA DMTF program with widespread industry
support with a set of standards including
CIM, CIM-XML, and WS-Management. The
CIM-XML protocol is most widely used with
WBEM today, and the term WBEM is often
used to mean this protocol.
Note: Firewalls should be configured to
allow the CMS to communicate with
managed systems through default port
5989. If you have modified the default port
setting for your WBEM provider, you must
configure your firewall for the port number
your WBEM provider on which it is actually
configured."
Web-Based Enterprise Management
(WBEM)
Identification, inventory, and eventsA DMTF standard for exchanging
management information using web
services. WS-Management may be used
to transport CIM as an alternative to
CIM-XML.
