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:
|
|
Web |
Click Power Management > Settings. 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. Click Save to apply the changes. |
CLI |
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.
