The Green Data Centre: Storage

Storing your savings

As disk prices come down, companies are increasingly using it for backup and archive functions that traditionally were tape-dedicated. Unlike tape, though, disks draw power even when they’re not in use. Minimizing the number of disks in use by de-duping and thin provisioning of data can save on power draw.

Prostor Systems may have the best of both worlds in its RDX removable disk technology. Like tape, it doesn’t draw power when it’s not in use, but when it’s plugged in, it still offers disk-like access rates, Wendt says.
