New data center survey shows mediocre results for energy efficiency |
April 12, 2013
A new survey suggests that large data centers might be less energy efficient than was previously thought.The survey, by Digital Realty Trust, quizzed 300 IT decision makers at large corporations in North America, each with annual revenue of at least US$1 billion or with at least 5,000 employees.The results revealed an average PUE (Power Usage Effectiveness) score of 2.9. PUE is a measure of data center efficiency, and lower scores are better. Ideal scores are close to 1.0, and previous surveys have estimated the average to be closer to 2.0.PUE is only one way of measuring energy efficiency and there's no standardized way of calculating it, so the finding isn't necessarily dire. But it's a data point suggesting that data centers might be less efficient on average than previously thought.To read this article in full or to leave a comment, please click here
