Generation Datacenters in Financial Services (Elsevier, 2009). Yet there is a disconnect, he says, between how data centers are designed and how they���re actually used. ���On the supply side, the data center factory has not been constructed to accommodate today���s fluid, ever-expanding demand,��� Bishop explains. ���Instead, the factory has taken more of a once-and-done approach to setup, with a one-size-fits-all approach to adding space, power and cooling.��� To remedy the situation, data center managers are moving away from the older facilities/construction-oriented approach toward one that involves developing capacity. This new approach adopts technology building blocks that are standard, modular and integrated with technologies that maximize space and labor while minimizing energy use, Bishop says. These developments are themselves part of a larger, ongoing IT transformation. ���The data center has evolved quite dramatically over the years,��� says Terrence Clark, General Manager, DCIM, Energy & Sustainability Solutions, at CA Technologies. ���For many years, when it came to available capacity, space had been the limiting factor. But that is changing quite rapidly. Now, most often we hear that the limiting factor, when it comes to data center capacity, is power.��� Here���s why: Although servers have gotten smaller, they���ve also become increasingly powerful. ���As a result, servers not only consume more energy, but also can be placed closer together,��� Clark says. ���This increased density allows data center managers to get more compute power per square foot.��� This also makes it essential for organizations to have a more accurate understanding and greater visibility of energy consumption in the data center, Clark says. ���No longer can data center managers rely on the fact that, as long as they have available space to place a new rack or server, they can deploy it,��� he says. ���Without knowing the power demand within their data center, they���re putting at risk the services that the data center delivers for the business.��� Companies need to identify where opportunities lie with regard to reducing energy usage, says Doug Kangos, a Partner in the sustainability practice at consulting firm PricewaterhouseCoopers. ���They really have to capture that information [about energy usage] to manage it,��� he says. Many organizations have begun to more carefully analyze their energy consumption, Kangos says, including not just the overall 38 smartenterprisemag.com 4 Tips for Greater Energy Efficiency Ensuring that your organization runs as energy-efficient as possible can be a big challenge. These tips, gathered from IT executives and industry analysts, will help you launch a sustainability strategy. n A ddress both current and future energy and sustainability issues in the data center, including space limitations, power, cooling and operational flexibility. Collaborate with your business-side colleagues on energy-consumption issues. n etermine whether you have a disconnect between how your data centers were D designed and how they���re actually used. If you do, mitigate this with technology solutions, facility redesigns, data center usage or some combination of all these factors. n D eploy technology tools that monitor, in real time, energy usage in your data center and throughout your IT infrastructure. Capture granular information about energy usage; this will let you better manage energy consumption and analyze trends. n M ake energy conservation and sustainability a priority for everyone in the organization, not just management. Educate all employees about the many ways they can conserve energy. costs but precisely how power is being used and how usage can be reduced. IT plays a critical role at these companies. In addition to helping reduce energy usage in the data center and other technology infra�� structure components, IT can help deploy systems and software to capture informa�� tion about a company���s sustainability efforts in a timely, efficient way, Kangos says. ���Sustainability efforts differ by company, as do their significance,��� he adds. ���They include power usage, greenhouse gas emissions, water usage, waste, community giving and investment, and workforce diversity. Systems are used to capture all that information.��� Following are the stories of four companies that use IT to operate with greater energy efficiency. Logicalis Gets a Handle on Energy Logicalis UK, a provider of technology solutions and managed services and maintenance, has made sustainability a priority. ���It���s particularly important to us that we can get a very good view of how we���re consuming energy, and the efficiency of our environment,��� says Simon Daykin, the company���s CTO. About two years ago, Logicalis deployed CA Data Center Infrastructure Management (CA DCIM), an energy monitoring and management solution from CA Technologies, to gain greater visibility of power consumption. Logicalis uses the technology to monitor its entire IT platform, including customers��� hosted infrastructures, as well as its own cloud platform. ���We operate multimegawatt data center facilities that consume absolutely huge amounts of power,��� Daykin says. ���We need to ensure that we���re consuming only the power we need.��� If Logicalis isn���t efficient in the energy it uses to deliver services, it might need to charge customers more for those services and therefore be less competitive, Daykin says, adding, ���Being able to ensure that we have a really efficient platform not only makes good environmental sense, but also makes good business sense. It ensures that we are as competitive as we possibly can be.��� Using CA DCIM, Logicalis has achieved an impressive 159 percent return on investment and an 11-month payback. The company had been using systems manage�� ment and monitoring solutions from CA Technologies, leading to what Daykin calls ���good synergies��� with CA DCIM and other IT systems management tools. DCIM has ���given us the insight we need into the environment,��� he adds. ���And it was relatively simple to deploy in our complex environment.��� Datotel���s Energy Forecast For Datotel, an IT service provider based in St. Louis, Mo., energy is one of its largest costs. That���s true not only as an ongoing monthly expense with utility providers, but also in terms of capital expenses for infrastructure needed to provide the high level of availa�� bility Datotel���s clients demand. ���Optimizing the efficiency of both the power we are using and utilization of the existing power delivery and data center cooling infrastructure is very important,��� says David Brown, President
