Cold Aisle Containment for Improved Data Center Cooling Efficiency (.pdf)
Increasing power requirements for new servers have created the need to support higher density computing platforms in existing data centers. With kW per rack averages increasing from 3kW/rack to, in some extreme cases, more than 30kW/rack, the need for providing more efficient ways of cooling
