Working with the Power Policy function

The Power Policy function supports to allocate less power and cooling to a system if the firmware supports and enables the Power Capping setting. This function helps to lower datacenter infrastructure costs and potentially allows more servers to be put into an existing infrastructure.

The Power Capping value is the value set for a rack or Blade server that will be capped by the firmware. The Power Capping value is persistent across power cycles for both rack and blade servers. If a Power Capping value is set, the system power consumption will not exceed the defined value.

If the Power Capping is supported and enabled for a server, the minimum and maximum Power Capping values of the server can be retrieved by Lenovo XClarity Integrator and displayed as a power consumption range for the server. In the following example, the minimum value is 0 and the maximum value is 750.
