The Cold Aisle Containment (CAC) approach encloses the cold aisle with ceiling panels above the aisle between adjoining racks and with doors at the end of the aisle. This allows the cold air from the perforated floor tiles in front of the cabinets to be contained and delivered to the server equipment air inlets. The CAC prevents cold air from mixing with warm air or being obstructed by surrounding equipment/sources before it reaches the servers. Because CAC possesses this ability, it is called focused cooling.
