Google Running 900,000 Servers 127
1sockchuck writes "How many servers is Google using? The company won't say, but a new report places the number at about 900,000. The estimate is based on data Google shared with researcher Jonathan Koomey, for a new report on data center power use. The data updates a 2007 report to Congress, and includes a surprise: data centers are using less energy than projected, largely due to the impact of the recession (buying fewer servers) and virtualization."
How about lower wattage CPUs? (Score:5, Informative)
We've moved from 1U systems with 90-125W systems to blade enclosures with 60W CPUs and also getting 4 or 6 cores per physical CPU rather than 1 or 2. While our HPC cluster core count has increased by a factor of 4 (allowing researchers to do more work), the amount of energy and floor space required did not increase that much at all.

In addition to this, Google runs DC power supplies, with a low-voltage on board battery as opposed to large rack UPS. I've heard they have some innovative tricks for server room cooling as well, but I've never seen confirmation of exactly what they're doing. But Google goes to great lengths to cut down data center power usage.

Dual-processor, two SATA hard drives, 12V PSU, 12V Lithium battery. It's not even sealed in a case, just a frame holding a board, with the PSU, battery and hard drives held on with Velcro.
Most of these will be about that spec.
