Set Power Management Settings for Power Policy on SPARC Servers

Before You Begin

  • The Admin (a) role is required in Oracle ILOM to modify the power management properties.

  • The Power Management Settings for Power Policy is supported only on SPARC servers.

  • As of Oracle ILOM 3.2.1, the Performance policy setting requires the Oracle VM Server for SPARC (Logical Domains Manager) 3.0 or later software to be installed on the primary domain. If an earlier version is installed, the Performance policy setting will behave as if the power management policy is set to Disabled.

This procedure provides both web and CLI SP instructions.

  • To set the Power Management Settings, perform one of the following Oracle ILOM interface procedures:
    Oracle ILOM Interface
    Set Power Management Settings for Power Policy Procedure
    Web
    1. Click Power Management > Settings.

    2. Enable one of the following Power Policy options:

      Disabled – When the policy setting is set to Disabled, all system components will run at full speed and power capacity.

      Performance – When the policy setting is set to Performance, unused and idle components in the system are placed into a slower speed or sleep state resulting in greater power savings with little impact on performance.

      Elastic – When the policy setting is set to Elastic, the system's power usage adapts to the current utilization level of the components. Components are brought into or out of a slower speed or a sleep state to match the system's utilization for those components.

    3. Click Save to apply the changes.

    CLI
    1. Type the following to set the Power Management Policy:

      set /SP/powermgmt policy=disabled|performance|elastic

      When:

      policy=disabled is set, all components in the system will run at full speed and power capacity.

      policy=performance is set, unused and idle components in the system are placed into a slower speed or sleep state resulting in greater power savings with little impact to performance.

      policy=elastic is set, the system's power usage adapts to the current utilization level of the components. Components are brought in to or out of a slower speed or a sleep state to match the system's utilization for those components.
