Select a CPU Power Management Policy
You set the CPU power management policy for a host using the vSphere Client.
Prerequisites
ESX/ESXi supports the Enhanced Intel SpeedStep and Enhanced AMD PowerNow! CPU power
management technologies. For the VMkernel to take advantage of the power management capabilities
provided by these technologies, you must enable power management, sometimes called Demand-Based
Switching (DBS), in the BIOS.
Launch the vSphere Client and log in to a vCenter Server system.
Procedure
1 In the vSphere Client inventory panel, select a host and click the Configuration tab.
2 Under Hardware, select Power Management and select Properties.
3 Select a power management policy for the host and click OK.
The policy selection is saved in the host configuration and can be used again at boot time. You can
change it at any time, and it does not require a server reboot.
Configure Custom Policy Parameters for Host Power Management
When you use the Custom policy for host power management, ESXi bases its power management policy on
the values of several advanced configuration parameters.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Select Custom for the power management policy, as described in “Select a CPU Power Management
Policy,” on page 344.
Procedure
