The name given to a specific controlled airflow layout associated with
enclosures and
cabinets. As more heat
becomes concentrated within the cabinet space, the risk of overheating and
damaging the equipment increases. *Contemporary thinking in data center thermal
management promotes the hot aisle/cold aisle layout where cold air is segregated
in front of equipment cabinets and hot exhaust air is expelled behind equipment
cabinets. This layout eliminates the direct transfer of hot exhaust air from one
system into the intake air of another system.
