How Google Cools Its 1 Million Servers

1sockchuck writes "As Google showed the world its data centers this week, it disclosed one of its best-kept secrets: how it cools its custom servers in high-density racks. All the magic happens in enclosed hot aisles, including supercomputer-style steel tubing that transports water — sometimes within inches of the servers. How many of those servers are there? Google has deployed at least 1 million servers, according to Wired, which got a look inside the company's North Carolina data center. The disclosures accompany a gallery of striking photos by architecture photographer Connie Zhou, who discusses the experience and her approach to the unique assignment."

Google faked some of the pictures

Google faked at least one picture. Take a look at this picture. [google.com]

The left-hand side is exact copy of the right-hand side. Take a look at the details: The halos from the lights and the texts in the white labels.

Immersion Would Be Better For the Environment

I'm really starting to like the idea that they should submerge all their servers in circulating liquid and cool them that way. It could absorb a lot more heat and it would probably make it a lot easier to reclaim the energy from the waste heat. Air has a really low specific heat. It's why they make fluffy down filled jackets; to trap the air which acts as a good thermal insulator (and getting it wet in the winter will kill you if you don't get somewhere warm because liquids conduct/transfer heat better due to greater specific heat).

No, they have an OCD photographer:

I’m obsessed with everything being symmetrical for all my work, so I cloned over the left servers to the right side. It just bothered me that there would be a hole when usually servers would be there. I wanted it to look beautiful, and symmetry is beautiful to me.
