Distributed Power Management (DPM) requires which technology to be available on the NIC?
Wake On LAN (WOL)
Once you turn on VMware DRS for your cluster you can enable the cluster for VMware DPM, which allows the power management of ESX hosts within the cluster. You must also ensure that Wake-on-LAN, IPMI, or iLO are functioning properly on your hosts. Only then can VMware DPM automate the power on and power off of ESX hosts using one of those methods.
