Server Green Design through Proportional Energy Use Per Google Engineers
Since most servers and server farms are running at less than fifty percent utilization, the energy efficiency of the data center computing assets is low. Google engineers recommend a energy proportional server design to deal with this reality. This is the future efficiency challenge for design engineers. ...
... "They should aim to develop machines that consume energy in proportion to the amount of work performed. Such energy-proportional machines would ideally consume no power when idle (easy with inactive power modes), nearly no power when very little work is performed (harder), and gradually more power as the activity level increases (also harder).
