If You Measure It, They Will Green

Data Center Energy Efficiency Metrics

A significant shift in data center economics is occurring, and threatens to overwhelm years of chip technology leaps. Data center energy costs are approaching 20% of the overall data center bill, and the purchase of a new server is often exceeded by the cost of power and cooling infrastructure to support that server. The data center power bill will continue to rise, and lifetime energy costs will soon exceed the cost of servers.

In August 2007, the U.S. Environmental Protection Agency (EPA) reported that U.S. enterprises spent $4.5 billion in 2006 on data center power bills. If current trends continue, this figure will rise to $7.4 billion in 2011. The projected load will require ten new power plants, while carbon emissions will rise 63%. Indeed, beyond the significant cost of energy, businesses and governments see this as a serious environmental issue. They recognize the need to increase power-consumption efficiency of data centers to reduce costs and environmental impact.
