Google Runs Data Center at 95F/35C Temperatures


As a general rule, if you want to keep a computer running without issues then you need adequate cooling for the major components. Google is always trying to make its servers more efficient and eco-friendly in a bid to save on running costs, and its St. Ghislain data in Belgium is now classed as the most efficient. It only uses fresh air cooling, which means no air conditioning units burning through electricity every day. Within the last four years that Google started measuring its Power Usage Effectiveness (PUE), the Belgium data center had a rating of 1.09 for the first quarter of 2011, and a 12-month average of 1.11, which lowered Google’s collective ten network operated PUE to a record 1.16 in the first quarter.

The peak operating temperature Google’s Belgium data center reached is 95 degrees Fahrenheit. It is governed by how hot it is outside, and when it reaches those temperature staff can no longer remain in the same areas as the servers; this could be solved with the right protective gear. By comparison, a typical data center runs at temperatures as low as 68 degrees. The savings Google makes by running at temperatures 27 degrees higher than other facilities must be huge. With the hardware in data centers clearly capable of coping with such high temperatures we should expect other facilities to take the same route in a bid to save money. The hot air pumping out of the server rooms can also be reused in a number of ways, e.g. to heat nearby homes.

Google in May 2011 increased tempto 80F- less than a year today, it is 95F.
