Description

Management 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

ICMP

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.

System identification, inventory and
events

Part of the SNMP specification, the
MIB is a model of the information to

MIB

be managed through SNMP. It is
equivalent to the CIM defined by
WBEM.

System identification, Inventory and
events

SNMP is widely used for management
but the widely implemented versions

SNMP

1 and 2 have weak security. While
no set operations are used by HP SIM,
read access to system data might be
visible on the network. SNMP is
UDP-based. 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 can be
suitable for some environments in
which the network used for managing
systems is relatively controlled.

Remote tool execution

SSH is used for remote command
execution. HP SIM uses SSH to run
commands on managed systems.

SSH

Consistent server management across
vendors

A DMTF initiative for common server
management which enables

SMASH

vendor-independent management
applications.

System identification

An SNIA standard for storage
management using WBEM.

SMI-S

Identification, inventory, and events

A DMTF program with widespread
industry support with a set of

WBEM

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: Configure firewalls 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.
