From Power Management -> Allocation –> Power Allocation Plan, the Target Limit value can be in watts or a percent between:
138 watts (Installed Hardware Minimum power) and
295 watts (Allocated Power)
Note - Installed Hardware Minimum power is the recommended minimum power you can set and should be regarded as a reference.
Capping the power to this minimum value will have two issues:
CPU performance will be severely downgraded.
You may see a “power violation” in the CLI and ILOM SEL log (described below). This is due to the minimum power calculation which is hard to perfect. The calculation's accuracy should be taken into account for each component and for different usage patterns. The Violation status occurs since the system is not able to reduce power to below the Installed Hardware Minimum power due to the usage pattern.
On the Consumption tab under Power Management in the ILOM Web interface, the following warning might be seen for the target limit:
In case of a hard cap, you might see Warning: /Peak Permitted/ exceeds /Target Limit/.
In case of a soft cap, you might see Warning: /Actual Power/ exceeds /Target Limit/.
Through the ILOM CLI, the event is recorded as follows:
/SP/powermgmt/budget Properties: activation_state = enabled status = violation
The ILOM SEL will record a IPMI log similar to the following:
ID = 10e2 : 10/27/2009 : 14:28:56 : Power Supply : PWRBS : State Asserted
To avoid this, do not cap the power to this minimum value.
