Controlling server power consumption

Control the server power consumption by adjusting the processor voltage and clock frequency.

By enabling the power saver mode, the power consumption can be reduced by adjusting the processor voltage and clock frequency. If power saver mode is disabled, the processor voltage and clock frequency are set to their default values.

Note: You can enable this option only when the server firmware is in the standby state or the running state.
To enable this option, you must have one of the following authority levels:
  • Administrator
  • Authorized service provider

To control server power consumption, complete the following steps:

  1. On the ASMI Welcome pane, specify your user ID and password, and click Log In.
  2. In the navigation area, expand System Configuration > Power Management > Power Mode Setup.
  3. In the right pane, select any of these options:
    • Disable Power Saver mode: Disables the Power Saver mode. The processor clock frequency is set to its nominal value and the power that is used by the system remains at a nominal level.
    • Enable Static Power Saver mode: Reduces the power consumption by lowering the processor clock frequency and the voltage to fixed values. This option also reduces the power consumption of the system while delivering predictable performance.
    • Enable Dynamic Power Saver (favor power) mode: Causes the processor frequency to vary based on the processor use. During periods of high use, the processor frequency is set to the maximum value that is allowed, which might be above the nominal frequency. Additionally, the frequency is lowered below the nominal frequency during periods of moderate and low processor use.
    • Enable Dynamic Power Saver (favor performance) mode: Causes the processor frequency to vary based on processor use. During periods of moderate or high use, the processor frequency will be set to the maximum value that is allowed, which might be above the nominal frequency. Additionally, the frequency is lowered below the nominal frequency during periods of low processor use.
    • Enable Fixed Maximum Frequency mode: Causes the processor frequency to be set to the maximum value that is allowed. This option increases the power consumption of the system while delivering maximum performance.
    Note: Enabling any of the power saver modes causes changes in the processor frequencies, changes in processor use, changes in power consumption, and varying performance.
