Trends in Server Energy Proportionality

Energy proportionality should be a key target in future server design. Although energy proportionality, as quantified by the proposed EP metric, has improved significantly in recent years, much more can be done to move systems closer to ideal energy proportionality. Toward this end, we are pursuing a workload characterization and large-scale system simulation methodology for advising data center system integrators to move toward cost and power-efficient infrastructures.
