DC power offers an ideal solution here. Servers with DC power supplies, in a datacenter with a DC power distribution system, offer the ability to deploy extremely dense server racks because they are on average 20% more efficient than their AC equivalents (see <a href="http://www.rackable.com/docs/tollyrackablec1001.pdf)" rel="nofollow">http://www.rackable.com/docs/tollyrackablec1001.pdf)</a> and therefore eliminate a significant amount of heat. By reducing the power losses and resulting heat, hot spots become much less of an issue. In fact, a Rackable DC-powered server configuration can get rid of hot zones altogether with their internal rack hot aisle design.
