VMware Distributed Power Management is one of the real benefits of having a virtual environment for me, since with this, we will be able to reduce electricity consumption in our data center by a lot. VMware DPM Allows Unnecessary ESX Hosts to Be Powered Off, and when virtual machines are loaded and require more physical servers, these start automatically. All of this would be achieved in a DPM-enabled DRS cluster. The power consumption of a server is 15W when it is in Standby mode and depending on the server and its components it can vary approximately between 300W and 500W when it is booted. Starting from this, we can calculate how much we can save if we opt for VMware and set up a VMware DRS cluster + VMware DPM. Example:
