When the vSphere DPM feature is enabled, hosts might be placed in standby mode (that is, powered off)
to reduce power consumption. The unreserved resources provided by these hosts are considered
available for admission control. If a virtual machine cannot be powered on without these resources, a
recommendation to power on sufficient standby hosts is made.
