Facebook’s big data center in Prineville is pretty much an open book. The company is literally open-sourcing its data center and server designs, showing how the social-networking giant is stripping IT gear to bare essentials, with the goal of having a PUE – the industry-standard measure of energy efficiency in data centers – as low as possible.
At this point, the ratings for Facebook’s Prineville is well under the industry average of 1.5 PUE.
It’ll be interesting to see how the major vendors of IT gear react to the Facebook approach. Take servers, as an example. Facebook – in keeping with its barebones approach – strips its servers of any plastic casing and even unnecessary screws. The result is a server chassis with 22 percent fewer materials, no expansion slots, and weighing six pounds less than the comparable mass-market server.
Facebook also arranges racks as triplets for easier deployment and swapping, and has simplified its servers’ power supplies to achieve efficiency of greater than 94 percent.
Of course this approach to server architecture eliminates the manufacturer’s plastic skin along with any trace of product branding. “The upshot here is that many IT buyers will look at Facebook designs and incorporate them into what they do,” observes Larry Dignan at ZDNet. “It’s highly likely that technology vendors will have to respond.”
