Google Uses About 900,000 Servers
Found on Data Center Knowledge on Sunday, 31 July 2011
Recent guesstimates have placed Google's server count at more than 1 million. But new data on Google's energy use suggests that the company is probably running about 900,000 servers.
"Google's data center electricity use is about 0.01% of total worldwide electricity use and less than 1 percent of global data center electricity use in 2010," Koomey writes.
The company has designed a new storage and computation system called Spanner, which will seek to automate management of Google services across multiple data centers.
With an amount like that, numbers don't really matter that much anymore. Its not like you have to long into them manually to admin the server anymore.
