The hot aisle /cold aisle data center layout was originated by IBM in 1992 and it is one of the oldest ways to save energy in the data center. Assuming a computer room is configured in such a way that either is an option, hot aisle containment may be seen as the better option because it has some thermal efficiency and ride-through advantages. However, because every computer room is unique, there is no one definitive solution. The HAC system directs the upward airflow to an AC return system such as a drop-ceiling void. The system simply aligns server fronts (air intakes) toward a shared cold aisle, and backs (exhausts) toward a shared hot aisle. Cold Aisle: Rows of racks face each other, forming a corridor where cool air is directed.
