Maintaining the datacenter at an efficient temperature. Datacenter cooling not only involves the deployment and maintenance of air conditioning, but in order to provide the most cooling per square foot, the most efficient server configurations must be employed. For example, rack servers are more efficient than stand-alone servers, and blade servers are more efficient than rack servers. The type of heat sinks and CPU coolers used in each server are also a factor. See KyotoCooling
Local Smart Cooling
Smart cooling is a type of datacenter cooling that monitors specific areas within the facility and adjusts the temperature locally rather than the entire room. Dynamic Smart Cooling (DSC) was an earlier HP solution for smart cooling.
Develop a Heat Map
A definitive way to determine the airflow in a room is to generate a heat map. The analysis of heat flow can be used to locate air leaks and determine how to relocate equipment for greater airflow.
