Facebook already has built a couple of their own data centers and their own servers. Now Facebook is building their own storage hardware for keeping all of the digital content uploaded by their 800+ million users. ?We store a few photos here and there,? stated the Facebook hardware design head Frank Frankovsky in an interview with Wired. Facebook is estimated to be storing about 140 billion digital photos.
At their data center in Oregon, Facebook stopped using electric chillers and uninterruptible power suppliers. By working with various hardware manufacturers, the company was able to reduce their power consumption. Frankovsky calls this “vanity free” engineering.
?We?re taking the same approach we took with servers: Eliminate anything that?s not directly adding value. The really valuable part of storage is the disk drive itself and the software that controls how the data gets distributed to and recovered from those drives. We want to eliminate any ancillary components around the drive ? and make it more serviceable,? stated Frankovsky. ?Break fixes are an ongoing activity in the data center. Unfortunately, disk drives are still mechanical items, and they do fail. In fact, they?re one of the higher failure-rate items. So [we want to] be able to quickly identify which disk has failed and replace it, without going through a lot of mechanical hoops.?
