reduced, the consumption must be adjusted to match the change. Some examples of sudden capacity
reduction include loss of external power, chiller failures, and utility company demands for cutbacks.
The Data Center Power Control facility provides a means to pre-define the responses to such events, creating
flexible rules in Systems Insight Manager that can be invoked when such events occur. The rules can determine
the set of systems that need to be adjusted based on criteria evaluated when the event occurs. The rules also
specify actions that should be taken on those systems. These rules allow for flexible event responses such as
"shut down all of the low-priority systems in the data center and make the medium-priority systems operate
in low power mode."
Some of the other scenarios are:
•
Data center monitoring detects that an external power source has failed, or is about to fail. The data
center continues to operate on a backup power source, but load must be reduced to make the best use
of the limited capacity of the UPS.
•
Data center monitoring detects that a chiller has failed, or is about to fail. The data center continues to
operate, but load must be reduced so the data center stays cool (and the critical workloads stay up)
as long as possible.
•
Data center management is asked by the local utility company to reduce data center power usage by
some proportion.
•
A failure in a primary data center triggers the need to bring up a standby data center.
The Data Center Power Control facility can be used to handle all of these scenarios and many others.
The Data Center Power Control facility has two pages. The Data Center Power Control Rules page is
used to define rules and the Data Center Power Control page is used to invoke the rules.
Security properties
Protocols and ports numbers
Insight Control power management uses the following ports or external interfaces to aid administrators in
deployment and proper operation of the power management features:
Default port number Protocol System/Device
443 SSL HP ProLiant and Integrity iLO
443 SSL HP c-Class Onboard Administrator
22 SSH Servers
5989 WBEM HTTPS Integrity Servers
161 SNMP PDU/PDR
50443 SSL HP Monitored PDU
Configuration for PDR/PDU monitoring via SNMP
HP Monitored PDRs/PDU, and third party PDUs utilize the SNMP protocol to enable discovery and monitoring.
The interface that allows network communications to the PDR/PDU is called the PDU Management Module.
To enable SNMP-based monitoring and discovery of the power delivery hierarchy, perform the following:
1. Ensure that the appropriate SNMP Read community string specified in the Systems Insight Manager
Global Credentials page, or on the system’s System Credentials page, matches the community string
in use on the management module.
2. Enable SNMP protocol on the device via its management interface.
3. For HP PDRs/PDUs you must additionally specify the address of the Systems Insight Manager CMS as
an SNMP Manager in the management interface of the PDR/PDU.
Configuration for PDU Monitoring via SSL
If your HP Monitored PDU supports discovery/monitoring via the SSL protocol, you must provide the
appropriate sign-in credentials for the system in the HP Systems Insight Manager Global Credentials page,
