THE DATA CENTER JOURNAL | 1 www.datacenterjournal.com Feature 2 8 Ways to Cut Data Center energy Costs By Lance Bishop and Russell Senesac Energy costs are a significant portion of the total cost of ownership (TCO) for data centers. In fact, energy can be 15–40 percent of operating cost; worldwide, data center power and cooling infrastructure wastes more than 60,000,000 megawatt-hours per year of electricity. To put this number into perspective, one single megawatt can power up to 1,000 homes on average. These facts stress the importance of data center energy management and the responsibility of data center owners and managers to implement and maintain energy-efficient technologies. 6 Data Center sustainability: More than Just alternative energy By Jeffrey R Clark, Ph.D Hardly a quarter goes by in which no major data center operator announces some new investment in solar, wind or another alternative energy source to power its facilities. Among the biggest investors in this area are Amazon, Apple, Facebook and Google. Although these companies garner headlines and, occasionally, grudging kudos from environmental groups such as Greenpeace, smaller organizations lack the wherewithal to emulate their efforts. But smaller data center operators can still take steps to be more sustainable (both environmentally and fiscally) without jumping into the utility sector. 12 gaining aWareness into Data Center energy issues By Linda J. Morrow New strategies involving the latest ideas, equipment and software are emerging all the time, and our incredible shrinking world is seemingly accelerating the speed of change. The price of electricity as well as incentives can vary greatly depending on location, and they factor into a facility's overall operating costs. As no two data centers are exactly the same, no one solution to improve efficiency is universally advantageous for all. 15 Data Center eFFiCienCy: Filtration anD Free Cooling By Jeffrey R Clark, Ph.D Cooling is one of the biggest energy consumers in the data center, surpassed only by the IT equipment that it serves. As such, it's a major target for energy savings, spawning a variety of design strategies and technologies, such as hot/cold-aisle containment, computational fluid dynamics and variable-frequency drives. 18 eFFiCienCy: six steps you're likely not taking By Jack Pouchet No public-company CEO would survive saying, "Our average employee productivity rate is 10 percent." Yet, we regularly accept that or less from our IT assets. Similarly, no CEO would accept workers showing up 10, 20, or even 50 percent of the time. Again, that's okay with most organizations when it comes to server utilization. 21 upCoMing events All rights reserved.
