  1. Power Cap: Allows users to set a wattage limit on power consumption. When applied on individual node, the node power consumption is capped at assigned level and when applied on enclosure, the whole enclosure power consumption is capped. When power saving is enabled, individual node or all nodes (enclosure level) runs in the lowest performance mode.

    • Select Enclosure Power Cap or Node Power Cap from the drop-down menu.

    • Enter a power cap value, check the box, and click on Apply to enable power cap.

    • Power cap enabled (checked) or disabled (unchecked) can be applied independent of power cap value. However, if power cap is enabled without any input value, the text box will be empty to represents that no user power cap value is specified and no power cap is enforced. If a value is entered and applied without enable checked, the value will be saved but not enforced.

    • Power cap value is limited in the range from minimum to maximum inventory power of the node / enclosure.

    • There are three types of power cap for Node domain. You can set User Power Cap value for each node.

    • Select enable in the Power Save section and click on Apply to activate the power save.
  2. Power Save: Can be applied with power cap simultaneously.

    • Select enable in the Power Save section and click on Apply to activate power save.

    • The following table provides details about power save modes.
