| IBM is working on a 120 petabytes of storage! |

The manufacturer IBM is working on the largest storage unit in the world, representing millions of gigabytes. At or larger storage media reach several terabytes public, builders are already above the petabyte (1,024 terabytes representative). As the record stood at 15 petabytes of storage, IBM opts for the decay with a unit combining no less than 120 petabytes.
This capability could be mad development by linking conventional hard
disk drives 200,000 from an average of 630 GB unit, to a total of 120
million gigabytes.
Specifically, this unit can store 120 petabytes of 24 billion MP3 (an average of 5 MB each), 24 million movies in HD, or 60 million copies of some 150 million pages that contain the All data on the Web. The great challenge of such a facility becomes clearer in the failures that can operate with some hard drives. To overcome the loss of data, the IBM system retrieves data from other storage media and writes slowly on alternate formats. If multiple failures operate, accelerating the reconstruction process to avoid future breakdowns, while erasing some data permanently. The plant also has the GPFS file system (General Parallel File System) from IBM, making it possible to send a unique data volumes exceeding the petabyte and spread over a large number of physical media. |
