Advanced Attributes
You can set advanced attributes for hosts or individual virtual machines to help you customize resource
management.
In most cases, adjusting the basic resource allocation settings (reservation, limit, shares) or accepting default
settings results in appropriate resource allocation. However, you can use advanced attributes to customize
resource management for a host or a specific virtual machine.

Description
When you set this attribute to the default value of static, VMkernel does not
directly set CPU power management states and only responds to requests from
the BIOS. When you enable this policy (set to dynamic), VMkernel dynamically
selects appropriate power management states based on current usage. This can
save power without degrading performance. Enabling this option on systems
that do not support power management results in an error message.
