So, this is pretty... big. At this very moment, researchers at IBM are decipherment the largest data drive ever -- a 120 petabyte beast comprised of some 200,000 normal HDDs working in concert. To put that into perspective, 120 petabytes is the equivalent of 120 million gigabytes, (or enough space to hold about 24 billion, average-sized MP3's), and significantly more spacious than the 15 petabyte mass found in the biggest arrays currently in use. To achieve this, IBM aligned discrete drives in horizontal drawers, as in most data centers, but made these spaces even wider, in order to accommodate more disks within smaller confines. Engineers also implemented a new data backup mechanism, whereby leak from dying disks is slowly reproduced on a or try your search for "replacement" at:

A system called GPFS, meanwhile, spreads stored files over group disks, allowing the machine to read or write unlike parts of a given file at once, while indexing its entire accumulating at breakneck speeds. The company big this divergence system for an unnamed client looking to conduct complex simulations, but Bruce Hillsberg, IBM's controller of storage research, says it may be only a matter of time before all cloud survey systems sport similar architectures. For the moment, however, he admits that his origination is still "on the lunatic fringe."
