1. As the power demand varies, Enclosure Dynamic Power Capping can share caps between
systems, it is the first place to investigate when capping and there is typically significant
capacity that can be reclaimed by applying caps to enclosures.
2. If you have multiple enclosures, reclaim similar percentages of capacity of the headroom from
each enclosure instead of a large amount of headroom from a single enclosure.
3. When applying power cap value to individual systems, you need to be careful not to impact
their performance because of increase in load beyond the historically observed loads result
in reduced performance. Again, reclaiming a small percentage of capacity from multiple
systems is preferable and less likely to have a significant impact on performance.
4. When reclaiming power delivery capacity, you must ensure not to remove or increase power
cap values without proper planning as it could lead to overload of the circuit capacity.
Task: Controlling the power of the PDU outlets
You can remotely enable or disable the power of an HP Intelligent PDU (iPDU) or the SNMP-based
third party PDU outlets such as APC rPDU and ServerTech CDU. The tool allows you to select an
outlet, system, or collection of outlets and systems. If a system is selected, the outlets powering the
system are added to the selection.
To control the PDU outlets, perform the following:
1. Select an outlet, system, or multiple outlets or systems.
2. Click Tool→PDU Management Module→Outlet Power. The Outlet Power page appears.
3. Select one of the following under System Power Control:
• Power on: Select this to turn the power on for all selected outlets.
• Power off: Select this to turn the power off for all selected outlets.
• Power cycle: Select this to turn the power off, then on for all selected outlets.
4. Click Run Now.
Task: Generating power topology for BladeSystem enclosures through
iPDUs
When the BladeSystem enclosure is discovered and connected to an HP Intelligent PDU (iPDU),
you can generate the power topology that supplies power to the BladeSystem through the iPDU.
For this purpose, you need not create a rack with the BladeSystem enclosures and add the power
connections to it to generate the power topology. You can either discover the BladeSystem enclosures
or iPDUs to view/visualize the power topology.
Task: Classifying systems by business criticality
Based on business criticality, you can classify systems using the Customize Collections option of
HP Systems Insight Manager. The systems that you want to classify are controlled by the collections
in the Systems by Service Class group. You can find the collections under Systems > Shared >
Systems by Service Class in the System and Event Collections tree view from the left pane of the
Systems Insight Manager home page.
To add service classes and remove or rename existing service classes, use the Customize... option
at the top of the tree view to change the set of collections within Systems by Service Class.
To classify a system, use the Customize... option to add the system to the collection for its service
class.
For more information on changing HP Systems Insight Manager collections, see Chapter 17
