Policies

A power policy is a set of configurations used to manage the power cap for a device or group. A policy is useful for

power management in different situations. For example, you can set up a policy to:

• Make sure power consumption does not exceed the capacity of the circuit.

• Schedule power usage according to the workload of the device/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, you could monitor current power consumption on a rack with ten device to

estimate how many additional devices you can add to the rack. Then, you can establish a power policy to cap

the total power consumption of the rack after the devices are added.

Power Center supports two 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 data center, room, aisle,

rack, or chassis.

From this screen, you can:

• Enable or disable a power policy

• Delete a power policy

• Create a new power policy

• Filter power policies so only certain policies display

• Edit a power policy

• View policy details including:

– Enabled: Whether the policy is enabled or disabled

– Active: Whether the policy is currently in use or not

– Entity Name: Name of the group to which the policy applies

– Policy Name: Name assigned to the policy

– Type: Static policy or dynamic policy

– Power Cap: Power cap for the group

– Date Range: Start and end dates defining when the policy is active

– Time Range: Time of day when the policy is active

– Days: Day(s) of the week when the policy is active

NOTE: If an emergency occurs—for example, power fails and devices are running on the UPS—you can initiate an

Emergency Power Reduction to minimize power consumption.
