20 | THE DATA CENTER JOURNAL www.datacenterjournal.com dRaw fRoM exisTing ResouRces If you haven't already imple- mented them, consider the 10 vendor-neutral steps of Emerson's Energy Logic framework (see Figure 2 ). e returns on several of the steps outlined in this article are quantified in Energy Logic and, with local incentives, may achieve paybacks in under two years. You also may want to consider joining an industry organization like e Green Grid, where you get not only access to some of the latest thinking on data center and IT resource efficiency but also, perhaps more importantly, access to your peers around the globe who have already tackled many of the issues you face today. Tapping that wealth of first-hand experience can help save you time and money, and avoid reinventing the wheel. MeasuRe! e old adage applies: what isn't measured isn't managed. Whether you use PUE, CUPS, SPECPower or a combination of them all, knowing where you stand and where you want to be is essential. If the Intel, SPECPower and CUPS infor- mation is anywhere near correct, the average enterprise data center operator who is achiev- ing 10, 15 or even 20 percent server-utilization rates can—with a detailed transition strategy and implementation plan—make significant progress toward reducing overall energy use and improving efficiency. Specifically, a facility can shut off 50 percent of servers, see a minor 4–10 percent workload increase on the remaining servers, cut the energy budget by up to two-thirds and still have plenty of headroom available for additional IT work- loads. at's a return every executive—CEO or CIO—would be proud to report. n about the author: Jack Pouchet is VP and Director of Energy Initiatives at Emerson Network Power and a Green Grid board member. Based in Southern California, he works closely with major OEMs in the server market, large data center users and leading mission-critical engineering firms to help define, architect and create opportunities for advanced power and cooling technologies that improve day-to-day operational efficiencies. He is a frequent writer and public speaker in IT sectors, including data centers, high-efficiency servers, storage, networking equipment, alternative energy and co-generation. something you need. An energy-efficiency audit from a trusted partner can help you put a program in place to take care of comatose servers and make improvements overall. An objective third party can bring a fresh perspective beyond comatose serv- ers to your whole efficiency picture. Figure 1 Figure 2 5 6
