Many efficiency best practices require minimal costs and don’t require expensive purchases to help <a href=”http://www.maintec.com”>Data Center Management</a> reduce CO2 emissions and lower their energy costs.In August of 2007, the Environmental Protection Agency published a report to congress on “Server and Data Center Energy Efficiency”. This report detailed the rapidly growing energy costs of data centers ($4.5 billion in 2006, $7.4 billion projected by 2011) and the dramatic increase in data center power consumption (61 billion kWh in 2006, 100 billion projected by 2011). The EPA report also explored implementing a new ENERGY STAR benchmark for data centers. Since the report’s publication, most major IT manufacturers announced “Green” products and initiatives. The EPA deserves kudos in trying to improve energy efficiency in data centers, but with so many competing manufactures now claiming to have energy efficient products, the prudent approach is to compare competing technologies and evaluate the energy consumption and life-cycle costs of all your new IT acquisitions. Even more important to your data center strategy is first gaining a solid holistic understanding of your data center environment and critical risk factors prior to investing in any new technologies.
