RT Journal Article T1 Leakage-Aware Cooling Management for Improving Server Energy Efficiency A1 Zapater Sancho, Marina A1 Ayala Rodrigo, José Luis A1 Tuncer, Ozan A1 Moya, José M.

Understanding the relationship between computational power, temperature, leakage, and cooling power is crucial to enable energy-efficient operation at the server and data center levels. This paper develops empirical models to estimate the contributions of static and dynamic power consumption in enterprise servers for a wide range of workloads, and analyzes the interactions between temperature, leakage, and cooling power for various workload allocation policies. We propose a cooling management policy that minimizes the server energy consumption by setting the optimum fan speed during runtime. Our experimental results on a presently shipping enterprise server demonstrate that including leakage awareness in workload and cooling management provides additional energy savings without any impact on performance.
