Enterprise data centers consume an alarmingly-high fraction of the energy produced in the United States. The US Environmental Protection Agency estimates that data center energy consumption will reach over 100 billion kWh by 2011, 2.5% of US power generation, resulting in an estimated annual electricity cost of $7.4 billion. As much as 40% of this energy is wasted because of two key inefficiencies: (1) the substantial energy used by idle equipment that is powered on, but not performing useful work, and (2) inefficiency in data-center cooling infrastructure arising from a poor match between where heat is generated and where cool air is supplied. This project proposes research on a data-center-wide management system that controls IT equipment, power, and cooling infrastructure in real time to save energy in two ways. First, it actively consolidates computing tasks onto fewer systems, allowing idle systems to be powered down. Second, it moves computing tasks to systems that can be cooled most efficiently. The project addresses the key challenge of modeling temperature in large-scale data centers and designing an autonomous system that makes correct decisions on where to place tasks.

企业数据中心消耗了在美国生产的能源的惊人一部分。美国环境保护局估计，到2011年，数据中心的能源消耗将达到1000亿千瓦时，占美国发电的2.5％，估计每年的电力成本为74亿美元。由于两个关键的效率低下，因此浪费了多达40％的能量：（1）怠速设备所使用的大量能量可以使用，但没有执行有用的工作，（2）（2）数据中心冷却基础设施效率低下，导致由较差的热量匹配在热量之间提供的较差的匹配，而在哪里提供了冷却空气。该项目提出了对数据中心范围内的管理系统的研究，该系统可以实时控制IT设备，功率和冷却​​基础设施，以通过两种方式节省能源。首先，它会积极地将计算任务合并到更少的系统上，从而使空闲系统被关闭。其次，它将计算任务移至最有效冷却的系统。 该项目解决了在大规模数据中心建模温度的关键挑战，并设计了一个自主系统，该系统正确决策就放置任务。
