Aisle Containment Systems FAQ
What is Aisle Containment?
Aisle containment is a cooling system that completely separates the cold supply airflow from the hot equipment exhaust air.
Aisle containment creates an even and consistent supply intake temperature for data center equipment and electronics. The returning air is warmer and drier when it reaches the AC coil.
Why is Containment so Important?
Aisle containment is an important environmental control standard in the data center industry because it removes the risk of servers and other sensitive electronics from overheating, which in turn saves companies upwards of thousands of dollars in energy costs a year. With a proper containment system in place the data center manager’s ability to fully separate cold airflow from exhaust air coming from hot equipment is an option that can be monitored precisely. The result is a supply temperature that is uniform and predictable.
There can be either hot or cold containment implemented, depending on your particular facility’s layout.
Active data centers run extremely hot.The worst enemy of a data center is a non-monitored, poorly designed system without sufficient aisle containment.Servers have their own internal cooling mechanisms, but the hot air from the surrounding environment still makes its way into the server intakes. The result is overheating, which results in reduced server performance and/or equipment damage due to excessive heat. The only solution to maintaining a constant temperature is aisle containment.
The data center manager’s primary responsibilities is to keep the machines operating at an ideal temperature, which is between 70° and 75° F. A lay person would suggest that a manager could simply cool the entire room. For many reasons, this is both inefficient and costly. Many data centers and server farms are extremely large structures with a plethora of air that needs constant cycling. Furthermore, the costs of managing a data center skyrockets as these facilities became larger and more complex.

Which is better, hot aisle containment or cold aisle containment?
The short answer is that both HAC and CAC are nearly equally effective because they prevent supply and exhaust air from mixing. Cold aisle containment (CAC) provides excellent control over supply temperatures to optimize CRAC set points. Hot aisle containment (HAC) returns warmer air to CRAC units which can increase cooling capacity. The best approach for your data center will be dictated by your site conditions. At most existing sites, it is easier to implement a CAC solution because there are typically cable trays and other obstructions above the hot aisle. It is also very difficult to implement hot aisle containment if there is not a return plenum. Our Project Managers can help you determine which approach would be most effective in your data center.
