    1. IBM brings solar power to data centers The company tomorrow will detail a pilot project that couples solar power with water-cooled servers that run on high-voltage direct current. The method results in about a 10 percent energy savings by reducing the losses that normally happen in converting from alternating power from the grid to the direct current servers run on, according to Kota Murali, the chief scientist of nanotechnology at IBM India who developed the pilot as a side project. That level of energy reduction is significant for large data centers with many servers, but the implications of solar and servers are potentially profound for places that don't have access to reliable power, Murali said. A bank, for example, that wanted to set up a remote branch and operate a data center could use solar power as a way to supplement power from the grid and on-site generators. IBM plans to offer the system in custom ... (Read Full Article)
