Power requirements for new servers are 10 times that of watercooled mainframes with the same size footprint, and they require 30 times the airflow. Legacy cooling designs were intended to deliver cooling to computer equipment along the length and width of a data center. Now designers face an added dimension - height. Air-cooled mainframes and racks of servers produce the same amount of heat as a 7 ft (2 m) tower of toaster ovens. These critical servers will shut down in moments without adequate cooling. They demand efficient, redundant and predictable cooling distribution designs.
