Gartner says 50% of data centers will have insufficient power and cooling capacity by 2008. Traditionally the power required for non-IT equipment in the data center (for example, cooling, fans and pumps) represented about 60% of total annual energy consumption. As power requirements continue to grow, energy costs will emerge as the second highest operating cost in 70% of worldwide data center facilities by 2009. However, a flurry of innovation is under way that will converge during the next three years to substantially mitigate the power/cooling issue.
