Settings within the VMware ESX server:

  1. Power management within the OS:

    There are four Power Management policies available in ESXi 5.0 and ESX/ESXi 4.1:

    • High Performance

    • Balanced (Default)

    • Low Power

    • Custom

    Choose High Performance to disable power management. If there is only one policy (Not supported), then the hardware either does not support power management, or its BIOS settings are configured to disallow OS-controlled power management.

  2. Power management via BIOS:

    Review the Power Regulator Modes in the BIOS settings. The following options are available:

    • HP Static High Performance mode

    • HP Static Low Power mode

    • HP Dynamic Power Savings mode

    • OS Control mode

Choose HP Static High Performance mode to disable power management. If OS Control mode is selected, refer above for disabling power management within the OS. Set the following in the ILO2.
