NYT : Asia Pacific Data Centers Hotter Than Ever

Friday, December 14, 2007

The Chinese, Indian and Indonesian economies are growing at a very fast rate, fueling growth for the overall Asia Pacific region, which also includes Australia, Hong Kong, Singapore, Taiwan, Thailand, Vietnam and other countries, Koomey said in a phone interview.  Worldwide electricity use doubled to 123 billion kWh by the end of the five years studied, including servers and associated cooling and equipment.  Total data center electricity costs reached US$7.2 billion annually, and further increases projected for 2010 would require the creation of 10 new 1,000-megawatt power plants, according to Koomey.  The huge increase points to a global problem exacerbated by data center managers not following best practices, such as using hot and cold aisles to optimize cooling and airflow, Koomey says.  “Most data centers are not operating at peak efficiency,” he says.  “What we find is that this is no fault of the people running them. They’re embedded in a system that has incentives that are a bit misplaced.”  For example, IT and facilities budgets are usually separate, so there’s no incentive for IT to spend an additional dollar to improve efficiency, even if that dollar results in five-dollar savings in the facilities budget, he says.  Plus, data center space is usually paid for by the square foot, even though most of the costs are for power and cooling rather than floor space.  “If you’re not showing people the cost of their actions, they’re not going to behave in a way that’s cost-efficient,” Koomey says…..In 2000, the United States accounted for 40% of all server electricity use, while Western Europe accounted for more than 25% and Japan a little more than 10%.  The United States share will decrease to 34% by 2010, while the Asia Pacific region’s share will become 16%, up from one-tenth in 2000, Koomey predicts.  Koomey calculated electricity use based on IDC’s data for server shipments and installed base.  Predictions are based on current trends, taking into account improved efficiency due to server virtualization and other factors.
