IBM Building The biggest Hard Drive With Capacity of 120 petabytes

IBM is building the biggest hard drive has a capacity of 120 petabytes, or 120 million gigabytes. Currently the world's largest hard drive capacity is 15 petabytes. If the project is completed, then IBM would 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 are combined into one in supercomputing facility. Implementation of projects is done in CA Research Lab, Almaden, San Jose, California, USA.

This giant hard disk can contain no less than a trillion files and can run a simulation of more complex systems, such as for weather and climate modeling. Megaserver was made for 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 software techniques. Coolers are made for these giant hard drive using water circulation, such as the cooling fan is not hard in general.

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

IBM uses a standard tactic to save multiple copies of data on different disks, but the hiring of new improvements that allow a supercomputer to keep working with nearly full speed even when the drive is damaged.
