A Look At How Google Cools Its Data Centers and Servers
Among other tidbits, the enter data center room severs as a cold aisle. You'll find raised floors, but not perforated tiles, and cooling coils use chilled water in order to act as the "ceiling" for hot aisles. Stainless steel pipes line the farm from end to end, too. In terms of details, the temperature in a data center has to remain at 80 degrees, which is no small feat given that many components put off heat well in excess of that figure. The VIA link below details the process further, and Google has confessed that it'll be shelling out even more information in the coming weeks.
