Energy efficiency and energy-proportional computing have become a central focus in enterprise server architecture. As thermal and electrical constraints limit system power, and datacenter operators become more conscious of energy costs, energy efficiency becomes important across the whole system. There are many proposals to scale energy at the data-center and server level. However, one significant component of server power, the memory system, remains largely un-addressed. The authors propose memory Dynamic Voltage/Frequency Scaling (DVFS) to address this problem, and evaluate a simple algorithm in a real system.
