Facebook Backs Up Data at Sub-Zero Datacenter PDF Print E-mail
Monday, 20 August 2012
Most tech companies invest heavily on their datacenter, and Facebook is one of such tech companies that own a gigantic server farm that measures 62,000 square-foot in size. Dubbed as the Sub-Zero datacenter, this particular datacenter’s primary role is to store the social network’s data, and whenever there’s an emergency restore, data from this datacenter would be used.

Nevertheless, what makes the Sub-Zero rather different from other datacenters is the fact that it utilizes far less electricity. A normal server rack can generally eat up to 4.5 kilowatts of electricity, but Facebook’s Sub-Zero only consumes a mere 1.5 kilowatts. The secret to the lower electricity consumption is that the servers are configured to fire-up specific hard drives when it’s needed only, thus providing electricity savings benefits in the process.
