How many servers do Microsoft actually have? Microsoft never says and no one seems to know for sure except the few numbers thrown around including a notable “10,000 new servers a month”, however, a recent promotional video produced by Microsoft’s Environmental Sustainability group may have accidentally spilled the beans.
The following screensshots are from taken from the video Q&A with Rob Bernard, Chief Environmental Strategist, at 2min 29sec to 2min 35sec for those of you playing at home.
Some quick stats gathered from the above clippings: 15 datacenters hosting 148,357 servers sitting on 17,406 racks consuming 72,500KW of utility power as of the end of January 2008 (as indicated by the bar chart). If you’re a bit of a imperial measurement person, that’s 97,000 horsepower. So the next time you visit Live Search, think of the horses.
