Google has thrown open the doors to its datacentres, publishing a whole site dedicated to photos inside the otherwise secretive locations, adding Street View to the centre in Lenoir, NC, and allowing Wired on site for a lengthy tour.
Google's data centres are impressive for a lot of reasons, chief among them probably being the sheer scale of it all. But this particular detail from Wired's look inside is pretty high on the list too:
Google realised that the so-called cold aisle in front of the machines could be kept at a relatively balmy 26-degrees Celsius or so-workers could wear shorts and T-shirts instead of the standard sweaters. And the "hot aisle," a tightly enclosed space where the heat pours from the rear of the servers, could be allowed to hit around 48-degrees Celsius. That heat could be absorbed by coils filled with water, which would then be pumped out of the building and cooled before being circulated back inside.
