Re: Energy consumption vs % utilization?
It's more or less the truth though. Only on rare occasions, such as the cluster/fail-over scenario given, can you actually supply less power to certain machines, and power use largely unrelated to their actual utilisation. Keep an eye on your UPS load during peak hours and you'll see the load rising when traffic and server utilisation rises, but compared to the baseline power needed to feed servers these fluctuations are peanuts. You supply a server with enough power to run...how is this waste exactly...? If anyone is wasting anything, it's perhaps hardware manufacturers that don't design efficiently enough, but power that you provide and that's used (and paid for) by your customers is not wasted IMO.
