Facebook’s 1 PetaByte box

facebook-logoFacebook has developed a prototype Blu-ray system capable of storing 10,000 discs and 1 petabyte of data in a single cabinet, with plans to scale it to 5 petabytes per cabinet. Blu-ray storage would save the company 50 percent in costs and 80 percent in energy usage over its existing hard-disk-based cold storage methods.

The 42U box was revealed at the Open Compute Summit in San Jose, California, on Tuesday and Facebook’s chief of infrastructure engineering Jay Parikh said the social networking giant plans to publish the designs to the wider community shortly.

The system’s access latency – limited by the time it takes to get a disc into a drive – is between 17 to 18 seconds and the aggregate read rate is about 240 megabytes per second.
