Hmmm... that's getting close to what I've wondered why you hear nothing of it -- running them on lower DC to match the power consumers low volts... Sure, I know, "power distribution voltage drops are less when you step up, flow low current, then step down." but a server farm can be a cabinet with a zillion blades nowadays...why not use a thick DC cable to run clusters? At least, I have not heard of it yet.
