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.
