Facebook is planning to construct a new cold storage facility to house archived and less-frequently-used media files. The new data center will reside in a new 62,000 sq. ft. building on the company's existing 127-acre property in Prineview, Oregon.
As cold storage, the data center will house servers with up to 3 Exabytes of total data capacity. The machines will be in a sleep state the majority of the time, but will be automatically turned on to serve up media files when accessed on the social network. Because the servers are normally in a lower-power sleep state, there will be a slight delay when users request files. According to Oregon Live, Facebook has stated that the delay will be as much as a couple of seconds and as little as several milliseconds.
The new cold storage facility will enable Facebook to save a great deal on electrical usage and hardware wear and tear (though primarily power bill savings). The company claims that its users upload 350 million photos each day, but that 82% of the social networking site's traffic focuses on a mere 8% of available photos.
Err, not quite the cold storage Facebook has in mind…
Considering Facebook's existing Prineview data center used a whopping 71 million Kilowatts of power in the first 9 months, moving to a new cold storage system for infrequently accessed files is an excellent idea. The photos will still be available, but Facebook will save big on the power bill–a fair compromise for retaining all of those lolcat and meme photos, i think.
The new data center will be rolled out in three phases, each measuring 16,000 sq. ft. in the Prineview facility. The first phase of cold storage servers should be up and running by Q4 2013. There is no estimate on the power savings, but it will be interesting to see how beneficial it will be–and whether other cloud service providers will adopt similar policies.
