The amount of energy used by data center servers, cooling equipment, and related infrastructure doubled in the United States and worldwide between 2000 and 2005, according to a new Stanford University study. The study credited a jump in the number of servers, driven by the insatiable demand for Web content — such as music downloads, Internet telephony and video-on-demand. Over the same time period, power costs grew by 132 percent, according to the report by engineering professor Jonathon G. Koomey.
With electricity now representing up to 70 percent of the cost of operating a data center, small and mid-size businesses need to consider not just how fast — but how efficiently — their servers run.
Hardware vendors who traditionally competed by claiming faster processors are now responding with new equipment that addresses the rising cost of operating data center equipment and growing concerns about climate change. In recent months, Dell, IBM, Hewlett-Packard and Sun Microsystems began marketing premium-priced servers that are more energy efficient but can save the added upfront cost in less than a year.
