Power Control

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

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 for a server, ensure that no service risk exists.

Page Description

On the menu bar, choose Power. In the navigation tree, choose Power Control. The Power Control page is displayed.

Parameter Description
Table 3-26 Parameters in the Power Adjustment section

Parameter

Description

Adjust the CPU working frequency

You can set the P-state to adjust the CPU working frequency. The number of P-states varies according to the CPU model.

Setting rule:
  • Among P-states, P0 indicates the maximum CPU working frequency.
  • P1, P2, and P3 indicate the CPU working frequency, power consumption, and system performance in descending order.

Setting method: Drag the slider bar.

NOTE:

The real-time power is influenced by the manually configured P-State and T-State status values. If the real-time power exceeds the power capping value when the power capping function is enabled, the P-State and T-State status values that are manually configured are invalid and automatically adjusted to the normal values.

Adjust the CPU duty cycle

You can set the T-state to adjust the CPU duty cycle. The number of T-states varies according to the CPU model.

Setting rule:
  • Among T-states, T0 indicates the maximum CPU duty cycle.
  • T1, T2, and T3 indicate the CPU duty cycle, power consumption, and system performance in descending order.

Setting method: Drag the slider bar.

NOTE:

The real-time power is influenced by the manually configured P-State and T-State status values. If the real-time power exceeds the power capping value when the power capping function is enabled, the P-State and T-State status values that are manually configured are invalid and automatically adjusted to the normal values.

Procedure

Setting the 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 under a parameter. For details about the parameters, see Table 3-26.
    NOTE:
    • Drag one slider bar at a time.
    • Adjusting the maximum CPU working frequency has greater impact on power consumption and smaller impact on system performance than adjusting the CPU duty cycle. Therefore, you are advised to adjust the maximum CPU working frequency first.
  4. Click Save.

    The following message is displayed in a dialog box:

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