IBM Builds Biggest Data Drive Ever

A 120 petabyte drive could hold 24 billion typical five-megabyte MP3 files or comfortably swallow 60 copies of the biggest backup of the Web, the 150 billion pages that make up the Internet Archive's WayBack Machine.

The data storage group at IBM Almaden is developing the record-breaking storage system for an unnamed client that needs a new supercomputer for detailed simulations of real-world phenomena. Nevertheless, the new technologies developed to build such a large repository could enable similar systems for more conventional commercial computing, says Bruce Hillsberg, director of storage technology at IBM and leader of the project.

The lunatic fringe now

"This 120 petabyte system is on the lunatic fringe now, nevertheless in a few years it may be that all cloud computing systems are like it," Hillsberg says. Just keeping track of the names, types, and other attributes of the files stored in the system will consume around two petabytes of its capacity.

Steve Conway, a vice president of technology with the analyst firm IDC who specializes in high-performance computing, says IBM's repository is significantly bigger than previous storage systems. "A 120-petabye storage array would easily be the largest I've encountered," he says. The largest arrays available today are about 15 petabytes in size. Supercomputing problems that could benefit from more data storage include weather forecasts, seismic processing in the petroleum industry, and molecular studies of genomes or proteins, says Conway.
