IBM introduced t a new category of server designed to address the technology needs of companies that use Web 2.0-style computing to operate massive data centers with tens of thousands of servers. Companies that operate massive scale-out data centers spend 10 to 30 times more on energy costs per square foot than a typical office building. The energy powers both hundreds of thousands of servers and the air conditioning needed to cool them. The growth of such data centers will continue as streaming video, online gaming and social networks spike Internet traffic, requiring companies to build ever vaster pools of computers that devour energy resources to operate 24 hours a day, 7 days a week.
