Power Control

Function Description
The Power Control page allows you to perform the following operations:
  • Power on, power off, or reset the server OS, or trigger the OS to generate a non-maskable interrupt (NMI).
  • Set the power restore policy for the server OS.

An NMI is a special interrupt that cannot be masked by using a standard interrupt masking technology. An NMI is generated typically when a non-recoverable hardware error occurs. Some NMIs can be masked by using special methods.

Before you perform power control on a server, ensure that the operation does not affect services.

GUI

Choose Power from the main menu, and select Power Control from the navigation tree.

The Power Control page is displayed.

Energy Saving Settings

Function Description

The Energy Saving Settings page allows you to adjust the P-states (CPU operating frequency) and T-states (CPU duty cycle) to reduce power consumption.

Energy saving settings may affect system performance. Exercise caution when configuring energy saving settings.

Before adjusting the server power, ensure that the following parameters are set on the BIOS:

  • EIST Support or EIST is set to Enabled.
  • ACPI 3.0 T-States is set to Enabled for a V2 server on the Romley platform.
  • ACPI T-States is set to Enabled for a V3 server on the Brickland platform. (ACPI T-States is unavailable for a V3 server on the Grantley platform.)
GUI

Choose Power from the main menu, and select Energy Saving Settings from the navigation tree.

The Energy Saving Settings page is displayed.



Parameter Description
Table 2-34 Parameters in the Power Adjustment area

Parameter

Description

Set Max CPU Operating Frequency

Drag the slider bar to adjust the CPU operating frequency (P-states).

The number of P-states varies according to the CPU model. P0 is the maximum value. A larger P-state value indicates a lower CPU operating frequency, and thereby lower power consumption.

NOTE:

If the actual server power exceeds the power cap value after the P-state and T-state are adjusted, the P-state and T-state values will be automatically adjusted to the normal values.

Set CPU Duty Cycle

Drag the slider bar to adjust the CPU duty cycle (T-states).

The number of T-states varies according to the CPU model. T0 is the maximum value. A larger T-state value indicates a lower CPU duty cycle, and thereby lower power consumption.

NOTE:

If the actual server power exceeds the power cap value after the P-state and T-state are adjusted, the P-state and T-state values will be automatically adjusted to the normal values.

Procedure

Configuring CPU Energy Saving Policy

  1. On the menu bar, choose Power.
  2. In the navigation tree, choose Energy Saving Settings.

    The Energy Saving Settings page is displayed.

  3. Drag the slider bar to adjust the CPU operating frequency or duty cycle.

    For details about the parameters, see Table 2-34.

    NOTE:
    • Drag one slider bar at a time.
    • Adjusting the maximum CPU operating frequency has greater impact on power consumption and smaller impact on system performance than adjusting the CPU duty cycle. Therefore, adjust the maximum CPU operating frequency first.
  4. Click Save.

    The following information is displayed:

    Are you sure you want to save power consumption settings?
  5. Click Yes.

    If "Operation Successful" is displayed, the setting is complete.
