Policy Priority Levels
When you create or update a policy, you can select different priority levels for each device/group. For
example, you can set priority levels based on the service level agreements associated with workloads
running on a device/group.
Power Center tends to reserve more power to the devices/groups with higher priority when the power
cap for devices/groups is not fully utilized.
For each device/group, you can set one of the three priority levels:
Low
Medium (Default)
High
Priority lists are policy-specific; however, a device/group may have different priority levels in different
policies. A higher-priority value of a device/group in a policy overrides the lower-priority value of the
same node in another policy.
For example, you created Policy1 for device <A, B, C> and Policy2 for device <B, C, D>, and you
configured different priorities or power caps for the policy with the same time slot. In this case, Power
Center follows these rules:
If there are overlapping policies on an entity, the policy with the lowest power cap is applied.
If there are overlapping dynamic policies on an entity and both are currently active, the highest
priority (High > Medium > Low) of this entity is applied.
Policy Modes
The policy mode is shown in the Enabled and Active columns in the Policies page. A green symbol
indicates Enabled or Active. Power Center supports three policy modes:
