With data center computers running 24x7x365, even a small increase in efficiency can really add up. Conceptually “hot aisle containment” is one of the simplest to envision and one of the hardest to implement since it normally involves a large amount of moving of the equipment racks. The concept here is to prevent the hot and cold air from mixing allowing the data center cooling devices to get better efficiency. The gains are large enough that power utilities in California are now doing rebates, with the University of California at San Diego partially funding their new data center with energy rebates.
