IBM, the giant in the field of IT is soon going to launch a new product. IBM is building the largest hard disk that has a capacity of 120 petabytes, or 120 million gigabytes. Currently the world’s largest hard disk capacity is 15 petabytes. If the project is completed, IBM would have a bigger hard drive in the world.
Certainly not a solo hard disk. IBM made the hard disk of a series of 200 000 hard drives that combine into one of the supercomputing facilities. Implementation of projects is done in CA Research Lab, Almaden, San Jose, California, USA.
This giant hard disk may contain at least a billion files and can run a simulation of more complex systems, such as 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 has developed a variety of hardware and new software techniques. Refrigerators are made for these giant hard drive by water circulation, not the hard drive cooling fan in general.
When one disk dies, the system takes data from another disk drive and disk replacement write slowly, so that the supercomputers can continue working. If more failures occur between nearby unit, the unit will be the reconstruction of speed the process and avoid the possibility of failure, such as the elimination of some data permanently.
IBM uses a standard tactic to keep multiple copies of data on different disks, but uses the new enhancements that enable a supercomputer to keep working at almost full even when the unit is damaged.
