Then, you can determine the amount of power that must be reclaimed to make the necessary
power/thermal capacity available in the rack.
When applying caps, use the following guidelines:
•
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.
•
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.
•
When applying a power cap value to individual systems, you need to be careful not to impact
their performance because an increase in load beyond the historically observed loads can
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.
•
When reclaiming power delivery capacity, you must be sure not to remove or increase power
cap values without proper planning because 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:
1.
Select an outlet, system, or multiple outlets or systems.
2. Select 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 and then on for all selected outlets.
4. Click Run Now.
