datacenterEnergy News: Two interesting stories today from eWeek: first, the Green Grid member companies signed a Department of Energy agreement for data center metrics; second, coverage of Energy Star director Andrew Fanara's declaration that volume servers are so obviously bad for the green agenda. For the first story, DOE officials said they'd like to see 10 percent efficiency improvements by 2011, and they'll make available resources from the Lawrence Berkeley National Laboratory. In the second story, "Fanara said he's been talking to 'virtually all' of the major server makers and says they are all on board with the EPA as far as improving future versions of the products to make them more energy efficient." (Others say mainframes are coming back; how does that impact energy plans?)
