Configuring power capping settings
The Power Capping Settings section enables you to view measured power values, set a power
cap, and disable power capping.
•
The Measured Power Values section lists the following:
Maximum Available Power—The power supply capacity for a nonblade server, or the
initial power-on request value for a blade server
◦
◦
Peak Observed Power—The maximum observed power for the server
◦
Minimum Observed Power—The minimum observed power for the server
During POST, the ROM runs two power tests that determine the peak and minimum observed
power values.
•
Power capping settings are disabled when the server is part of an Enclosure Dynamic Power
Cap. These values are set and modified by using Onboard Administrator or Insight Control
power management.
•
Use the Power Cap Thresholds as guidelines for configuring a power cap.
Maximum Power Cap—The maximum power available for the server. The server must not
exceed this value.
◦
◦
Minimum High-Performance Cap—The maximum power that the server uses in the current
configuration. A power cap set to this value does not affect server performance.
◦
Minimum Power Cap—The minimum power that the server users. 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 below the
power cap value.
•
You cannot use the iLO web interface to configure the power capping settings for SL servers.
Use one of the following tools to configure the power capping settings for SL servers:
◦
Power Interface Control Utility—This utility is available at the following website:
◦
HP ProLiant SL Advanced Power Manager—For more information, see the HP ProLiant SL
Advanced Power Manager User Guide.
To configure a power cap:
1.
Navigate to the Power Management
→Power Settings page, as shown in
2.
Select the Enable power capping check box.
3.
Enter the Power Cap Value in watts, BTU/hr, or as a percentage.
The percentage is the difference between the maximum and minimum power values. The
power cap value cannot be set below the server minimum power value.
When values are displayed in watts, click Show values in BTU/hr to change the display to
BTU/hr. When values are displayed in BTU/hr, click Show values in Watts to change the
display to watts.

Click Apply.
