I don't know how data centers are set up, so this is a comment made in ignorance: I'm surprised this isn't built into the electrical service for the rack. Only distantly related: I kept tripping a breaker in my kitchen while making breakfast. It took me the longest time to figure out that I could run my toaster and coffeemaker at the same time, but if the fridge compressor kicked on while I was doing that, it would overload the circuit. It took me so long to figure out what was going on because I was always dealing with this situation before I'd had my coffee.
