Todays data centers are increasing computations per watt, but computation demand is increasing even faster, so overall energy use is increasing. The lifetime electrical cost of operating a data center may soon exceed the cost of the IT equipment. However, IT equipment load can be controlled.
Reducing the IT power requirements through energy-efficiency improvements cascades through the data center and results in a multiplier effect through savings on infrastructure power: Every unit of IT power saved reduces infrastructure power to energize and cool the IT equipment. Data Many energy efficiency opportunities involving IT equipment such as servers, network, and storage remain untapped. Data center owners and operators can take advantage of not only higher efficiency IT equipment, but also data center management strategies such as utilization, consolidation, and virtualization to prevent excessive IT energy consumption.
