What is a cold aisle containment system?

Cold aisle containment systems are designed to eliminate hot-spots within server racks, server rooms and datacentres. These hot-spots typically occur at the top of server racks and are affected by hot exhaust air circulation. Cold aisle containment forms an enclosed ‘cold aisle’ over the top of the racks and by using sliding doors at both ends of the containment. By managing air flow at the top of the server racks, more of the space within the server rack cabinet can be used, reducing the space cost per server in the rack and the costs of cooling can be reduced.
