Are you still running individual servers because although you know you will save a lot of space by virtualising, you are unsure how much energy you will save?
With the Schneider Electric Virtualisation Energy Cost Calculator you can compare the energy savings from the virtualisation of servers. This tool shows the before and after power usage effectiveness (PUE), an estimate of electricity bill savings, a breakdown of where the energy savings come from – server reduction, power and cooling systems – plus the amount of rack space you can save.
