How to Benchmark Data Center Energy Costs

January 12, 2009, 11:58 AM —  CIO — 

In the spring of 2007, UPS's Ben Swanson and Joe Parrino attended a conference on the growing problem of data center power consumption. One suggested remedy was to benchmark and analyze the power flowing through the data center. So after the conference, Swanson, the facilities department manager, and Parrino, a data center facilities manager, profiled their two main data centers to learn what they could do to increase their energy efficiency and, ultimately, save money.

They found one crucial area to improve: their 65 computer-room air handlers. Parrino and his team found that some of their power distribution units had perforated tops. "We were losing all sorts of air through the tops of the cabinets," he says, which meant that some of the cool air circulated by the air handlers was being wasted by cooling the PDUs. They restricted the air flow through the cabinets, tested to make sure they wouldn't overheat, then turned 24 air handlers off.

The move has saved UPS 1.6 million kilowatt-hours and about $124,160 per year. And that's not all-they also benchmarked their mechanical cooling system and were able to reduce its energy use, saving an additional $100,000 annually. The mechanical plant of these UPS data centers consumes about half what a typical data center mechanical plant consumes, according to their benchmarking study, Parrino says.

Sidekick: The Good News & the Bad News
Either way you look at it Microsoft Data Center management did not follow standards or best practices in this failure. In which case it makes me wonder more about the outsourcing of corporate data much less personal data.

AISO founders envisioned a Web hosting company that was environmentally friendly. While the company employed energy-efficient innovations like solar panels, its infrastructure produced unacceptable power and cooling requirements. Find out how AISO leveraged AMD technology to overcome their challenge in this case study white paper.

In this whitepaper, Scalar explores the opportunity to change the landscape with respect to mission critical databases built around Oracle. Leveraging technologies such as Linux, high-end commodity processing power and Oracle RAC technology to architect, design, build and maintain database infrastructure that delivers maximum availability, reliability and performance at a fraction of traditional cost.

On a typical day, weather.com, the Web site for The Weather Channel in Atlanta, serves up between 15 million and 20 million page views. But in September 2004, when back-to-back hurricanes ransacked Florida, the peak traffic on one day more than tripled: over 70 million page views by more than 7 million unique visitors.
