Slideshow: 5 Tools to Prevent Energy Waste in the Data Center

But cost and environmental concerns had spurred a company-wide green initiative at NMS, a "CSI"-like crime lab near Philadelphia, and reducing HVAC costs was one of the top priorities. NMS started implementing its green initiative last year, and the project will ultimately include virtualization in the data center and a solar power system to provide 30% of the company's power.  

"Who doesn't want to reduce costs?" Tait says. "[We started] this before the economy even tanked."

Tait is one of many IT executives who will be sharing their stories and best practices at Network World's IT Roadmap Conference & Expo in Philadelphia next week, one of 10 such events being held in various U.S. locations throughout 2009.

NMS Labs handles clinical toxicology and forensic testing, often for criminal cases. It's not as glamorous as "CSI" but "it's interesting, certainly," Tait says. "We get everything from blood work resulting from a run-of-the-mill DUI stop all the way up to DNA evidence under a murder victim's fingernails."

NMS has about 75 scientific instruments, 50 servers and 350 computers overall. Powering down devices that don't need to be on 24 hours a day has helped save energy, as have other initiatives, including upgrades to refrigeration, UPS and generator systems; video teleconferencing; automated power management systems; and using efficient light bulbs.

NMS has cut electricity costs by roughly 15% to 20% and has more cost-saving projects on the way.

The company is planning a solar panel project that could provide 25% to 30% of its power by next year. With tax incentives, the project is a no-brainer, according to Tait.

Inside the data center, upgraded cooling equipment and virtualization will play key roles. Tait is building a new data center that will replace four out-of-date air conditioning units with two larger ones. He is also phasing out older servers and planning to virtualize new ones that replace them.

"We've got about 50 servers in our data center and we're thinking virtualization can cut that in half," he says.
