Power capping considerations
• During POST, the ROM runs two power tests that determine the peak and minimum
observed power values.
Consider the values in the Power Capping Settings table when determining your power
capping configuration.
◦ Maximum Available Power—The Maximum Power Cap threshold. The server must not
exceed this value. This value is the power supply capacity.
◦ Peak Observed Power—The maximum observed power for the server. This value is the
Minimum High-Performance Cap threshold, and it represents the maximum power
that the server uses in the current configuration. A power cap set to this value does not
affect server performance.
◦ Minimum Observed Power—The minimum observed power for the server. This value is
the Minimum Power Cap threshold, and it represents the minimum power that the
server uses. A power cap set to this value reduces the server power usage to the
minimum, which results in server performance degradation.
• When a power cap is set, the average power reading of the server must be at or lower than
the power cap value.
• Power capping is not supported on all servers. For more information, check the server user's
guide.
Configuring SNMP alert on breach of power threshold settings
The SNMP Alert on Breach of Power Threshold feature enables the sending of an SNMP alert
when power consumption exceeds a defined threshold.
Prerequisites
Configure iLO Settings privilege
Procedure
1. Click Power & Thermal in the navigation tree, and then click the Power Settings tab.
2. Select a value in the Warning Trigger list.
3. If you selected Peak Power Consumption or Average Power Consumption, enter the
following:
• Warning Threshold
• Duration
4. Optional: To change the Warning Threshold display to Watts or BTU/hr, click Show values
in Watts or Show values in BTU/hr.
