Facebook has a whole spate of data point to put in , but much of it seat so late within our profiles that it seldom require to be function . So the societal internet has been trying to get moth-eaten storage systems to file elderly content off — and a new prototypeuses Blu - Ray disk .
Whilst talking at this yr ’s Open Compute Summit , Facebook ’s frailty chairman of engineering , Jay Parikh , explain how a prototype cold storage system could allow the societal internet to free up full of life space on its servers . The young system , he explained , apply 10,000 Blu - ray discs at a time to put in a petabyte of data .
The systemuses a automaton arm to pluck specific discs from a large cartridge , each of which is held in a larger cartridge holder . Despite those kinds of mechanics , the new organization could save Facebook 50 per centum in cost and 80 percentage in vigour use when compared to standard HDD cold storage techniques .
The prototype is apparently already in utilisation , and all told Facebook has 30 petabytes of store in this human body . consort to GigaOm , that will be joined by a second similar resourcefulness soon , and it should expand up to 150 petabytes within a few calendar month . Some way off the 3 exabytes the site requires , but a footprint in the right direction . [ GigaOmviaArs TechnicaviaVerge ]
