Energy-Efficient Cooling Strategies for Servers Analyze and Control Leakage and Fan Power

摘要

Many servers are overcooled, partially because of the manufacturers' safety margins. It's possible to reduce the cooling energy used by enabling the processor temperatures to rise within safe limits. However, leakage power increases at high temperatures and can cause excessive energy waste. This article discusses how to simultaneously minimize the cooling and leakage energy. ;Welcome to my new column, Green Computing. I will be writing about energy-efficient software and hardware design strategies, opportunities for electricity cost savings and battery-life extension, system-level policies for energy and thermal management, and smart infrastructures for improving efficiency.
