Policies
A power policy is a set of congurations to manage the power cap for a device or group. A policy is useful for power management in
dierent situations. For example, you can create a policy to:
• Power Cap — Make sure that power consumption does not exceed the capacity of the circuit.
• Control Power Usage — Schedule power usage according to the workload of the device or group. For example, you can set an
aggressive cap when the workload is low, enabling a reduction of power use for your data center.
• Increase rack density — For example, monitor the current power consumption of a rack with 10 devices to estimate how many more
devices you can add to the rack.
Power Center supports three power cap policy types:
• Static — Manually set the power cap for each device in a rack or chassis.
• Dynamic — Power Center dynamically allocates the power cap for each device in a group (data center, room, aisle, rack, or chassis).
• Temperature Triggered Policy — The power cap is allocated depending on the changes in the temperature, based on the American
Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) standards.
From the Policies screen, you can:
• Create a power policy
• Edit a power policy
• Enable or disable a power policy
• Delete a power policy
• Refresh the list of policies
• Filter power policies so only certain policies are displayed
• Sort the list of policies
