IBM Create Largest Capacity Hard Drive 120 petabytes

IBM is building the largest hard drive that has a capacity of 120 petabytes, or 120 milliongigabytes. Currently the world's largest hard drive capacity is 15 petabytes. If the project is completed, then IBM will have a hard drive with the largest capacity in the world.

Certainly not a single sebuahhardisk. IBM makes the hard drive of a series of 200 thousand hard drives joined together in supercomputing facility. Implementation of projects is done in CA Research Lab, Almaden, San Jose, California, USA.

This giant hard disk can contain not less than one trillion files and can run a simulation ofmore complex systems, such as for weather and climate modeling. Megaserver was madefor an anonymous client who plans to create a simulation of the phenomenon of real events.

To support this project, IBM developed a variety of hardware and new softwaretechniques. Coolers are made to this giant hard drive using a circulating water, such ascooling fan is not hard in general.

When a single disk dies, the system draws data from another drive and write to diskreplacement slowly, so that supercomputers can continue working. If more failures occur among nearby drive, the drive will rebuild the speed to process and avoid the possibility ofother failures, such as the vanishing of some of the data permanently.

IBM uses the standard tactics of storing multiple copies of data on different disks, but thehiring of new improvements that allow supercomputers to continue to work with almost fullspeed even when the drive is damaged.
