It’s no secret: Energy consumption is skyrocketing as IT equipment proliferates across enterprises large and small. In fact, U.S. data centers ate up 61 billion kilowatt-hours of electricity in 2006, at a cost of $4.5 billion, according to the Environmental Protection Agency. That’s approximately twice as much power as they consumed in 2000—and the EPA expects data center energy consumption to double again by 2011.
Statistics like that have many IT professionals investigating “green IT” measures designed to cut power usage and shrink the carbon footprint of their IT operations. Yet only 15 percent of companies with at least 1,000 employees have an overall green IT implementation plan in place, according to an October 2007 survey from Cambridge, Mass.-based analyst firm Forrester Research Inc.
That’s not surprising. Going green can seem daunting, particularly where to begin. Fortunately, there’s significant overlap between going green and the simple common sense of running a tight IT ship. Buying energy-efficient new hardware is the first of five steps your company can take even if it doesn’t have a formal green IT initiative. Newer hardware almost always uses less energy, and there’s a good chance it will also come with energy-management tools that shut off the power automatically after lengthy idle periods.
First thing to do is to Update your Hardware.
But of course, that does not mean go on a spending spree. Figure out what you really need & eliminate everything else! Instead of running a bunch of useless printers, buy some multi-function machines that can be used for both coping & printing. Complete the green cycle by donating unused equipment to a retuable recyling place (see my previous posts on some good ones out there) or donate your equipment to charity.
Every 4-5 years in innovation & improvement in the IT Industry aim to deliver more efficient equipment. One year the power supplies will be more efficient & the year after that will be the LCD’s. Something is always changing for the better. Make sure to get the equipment that delivers the best energy performance.
Servers out there now come with CPUs designed to consume less engery. Servers using QUAD Core AMD Opteron processors have a significant performance boot without increasign power utilization & heat generation. AMD PowerNOW! Technology manages power utilization across all four processors dynamically, based on shifting application needs. And AMD CoolCore Technology reduces power consumption within each core, cutting power to unused transistors. PowerNow! Technology is also available in AMD Sempron, Turioin & Athlon processors for optimum power utilization in desktop & mobile computers. Those slick flat planel display monitors consume only one half to one third as much electricity as standard monitors. And newer backlit LED displays are even more efficient.
Secondly, if you are not using it turn it off!! Burning lights in unoccupied offices is a key source of waster electricity. Avoid this by installing a motion sensor control system that automatically turns off lights and even turns down the thermostat when people are not there. Have remote equipment monitoring tools that allow you to shut off idle audio-visual equipment without having to send someone manually. Deploy administrative systems with power managment features such as IBM Tivoli as well as IBM Maximo. Conduce user education to spread the energy savings word & remind everyone of their responsibility to do their part to turn things off etc. User a printer management system that helps you collect detailed information about who is printing what. You can use this to cut unnecessary printer usage. If your server & desktop hardware have advanced power management features that automatically shut down unused systems make sure they are enabled.
Third thing is no big surprise.. Virtualize, Virtualize, Virtualize. Virtualizing servers is far more efficient then simply purchasing new server hardware for each application you deploy, a strategy that can quickly result in server sprawl. By reducing the amount of hardware in your data center, aggressive virtualization can yield a sharp reduction in energy consumption. Thin Client computing consumes up to 80% less energy. Storage virtualization where multiple physical storage repositories behave like a single physical storage pool, can improve disk utilization, reducing wasted storage space that consumes power unnecessarily.
Next is Straighten out your Storage!!! Storing multiple instances of identical data in different places is neither green or smart. Scour your data for redundant instances and eliminate them in a process knows as de-duplicaiton. EMC & Symantec are two software vendors that offer products that de-duplicate data during backups. De-duplicated data backups are 25 times smaller then convential backup, resulting in significant savings on storage equipment and power utilization. Thin provisioning and dynamic capacity managment increases storage efficiency. Data compression, an old standby, can help save on hard drives too.
Next thing to do is to Consolidate your Data Centers!! Once you have virtualized your servers & consolidated your storage, you will probably notice a lot of extra space in your data centers. So much in fact, you should be able to shut down one or more of them slashing real estate and energy costs in the process. Consider building an entirely new facility! Doing so has some large upfront costs but years from now if you have the funding, it is a golden opportunity to implement green IT measures from the ground up! If you have already done that, you are ready to contemplate more exotic technologies such as solar and wind power.
Whether or not you embark on such advanced initiates, taking even the most basic step into a greener data center will make your company have more state of the art IT products for your coworkers, making your company more competitive and in turn help saving the planet.
