This is 100% the right answer: Microsoft’s Chiller-less Data Center. The Microsoft Dublin data center has three design features I love: 1) they are running evaporative cooling, 2) they are using free-air cooling (air-side economization), and 3) they run up to 95F and avoid the use of chillers entirely. All three of these techniques were covered in the best practices talk I gave at the Google Data Center Efficiency Conference  (presentation, video).

In a secretive industry like ours, it’s good to see a public example of a high-scale data center running hot and without chillers. Good work Microsoft.

James,

Any reasons you can think of that high-temp designs won't work on smaller data centers or server rooms?

I'm about to start designing a 60 KW server room, under intense pressure to cut operating costs. We're on the central California cost where outdoor temps rarely rise above 95 F and water shortages are a constant problem. I'm thinking free air cooling plus enough DX cooling to bring the temp below 90 F on those rare hot afternoons.

Good designs for smaller data centers and server rooms might save a significant amount of energy, money, and CO2.

It'll absolutely work well in a small center. In fact most of the large center designs are made of rooms or pods each of which is considerably smaller than a datacenter. 60kw is fairly small but I see no reasons why you couldn't do it at that scale. Intel did something along that scale with this containerized experiment: http://perspectives.mvdirona.com/2009/04/07/32C90FInTheDataCenter.aspx
