Double edge triggering technique for energy efficient server to reduce data center's impact on environment

摘要

Data centers worldwide have consumed massive amount of energy. The server processor energy efficiency has the biggest impact on energy usage in data center. In this paper, factors determining the processor circuit power are introduced and different power saving techniques are briefly reviewed. A novel methodology of using double edge triggering in server processor is proposed. By using the proposed double edge triggering implicitly pulsed CBS_ip flip-flop, the estimated energy saving of data center could be 4.3%; the energy saving on worldwide data centers will be estimated over 12 B kWh.
