Microsoft has been turning up the volume on its green initiatives across the company, as of late. I recently stumbled onto yet another one: DiskEnergy.

DiskEnergy is a Microsoft Research project headquartered at the company’s Cambridge, U.K. research facility. So far, there’s very little public information about it. But here’s a description of what’s in the works, courtesy of the Microsoft Research site:

Power consumption is a major problem for data centers of all sizes which impacts the density of servers and the total cost of ownership. This is causing changes in data center configuration and management. Some components already support some power management features, for example server CPUs support dynamic clock and voltage scaling that enables power requirements to be reduced significantly during idle periods. Storage subsystems do not have power management and are consume a significant amount of power in the data center. Modern enterprise grade disks require approximately 10W when idle. As storage requirements generally increase in data centers, the number of disks in data centers is increasing proportionally.”

The DiskEnergy researchers just published a white paper, entitled “Write Off-Loading: Practical Power Management for Enterprise Storage.” The team is planning to present its paper at the Usenix FAST conference in February 2008.
