Fascinating read here on the lengths that Goggle is going to make data center operations as efficient as they can be. There's a lot of gems here that I have never seen before, such the fact that running systems at non-peak levels is very inefficient, and it costs around $10 to $22 dollars per watt to build a data center, but only about 80 cents per watt to run it.
And there's also quite a bit of info on low level stuff, like how inefficient single threaded applications are, and how shared memeory models are difficult to keep up. Worth a readie.
