A new software called SleepServer has been developed by a team led by an Indian American scientist that will be able to save energy in the PCs in offices. Accessible via remote connections, the sleep-working enterprise PCs maintain their presence on voice over IP, instant messaging and peer-to-peer networks. The software reduces energy consumption by about 60 percent , according to a new peer-reviewed study presented by University of California, San Diego, computer scientists on June 24 at the 2010 USENIX Annual Technical Conference in Boston.

Yuvraj Agarwal, the UC San Diego Research Scientist in the Department of Computer Science and Engineering who developed SleepServer, said: "One of the big benefits of SleepServer is configurable on-demand wakeup. SleepServer enables enterprise PCs to remain asleep for long periods of time while still maintaining the illusion of network connectivity and seamless availability."

Attuned with existing networking infrastructure, SleepServer works with Windows and different versions of Linux and a Mac OSx version is being developed. It makes lightweight virtual images of sleeping PCs, which maintain connectivity and respond to applications on behalf of the sleeping PCs.
"According to our measurements, SleepServer provides $60 dollars of cost savings per PC on average over an entire year. By deploying SleepServer across the CSE Department, we expect to save approximately $60,000 dollars annually in direct energy costs alone," said Rajesh Gupta, Professor and Chair of the Department of Computer Science and Engineering at the UC San Diego Jacobs School of Engineering.
