Defining Data Center Aisle Containment & Which Strategy is Best for You

Data center containment is the process of separating cold supply airflow from hot equipment exhaust air. The separation of the two aisles helps reduce the use of energy and optimize performance of equipment in the data center. This all leads to increased air efficiency and up-time. Data center containment has emerged as an effective strategy for increasing a data center’s capacity and ability to support higher density rack loads for colocation and other key services.

There are many key benefits to have a containment strategy, including:

  • Reduced energy consumption
  • Increased cooling capacity
  • Increased rack space
  • Increased hardware life
  • Increased uptime to equipment

Now, you must ask yourself, what containment strategy will be most effective for my data center? There are two types of containments strategies to choose from, those being hot aisle containment systems and cold aisle containment systems. Both of which are very effective, but which one is best for you will be based on the characteristics of your infrastructure. Below we will go through the characteristics of each strategy to help push you in the right direction.

Cold Aisle Containment

With servers running day in and day out at all times, there is a significant amount of energy being used to maintain intake temperature to your IT infrastructure. It encloses the cold aisle of your data center, allowing the rest of it to become a large hot-air return. By containing the cold aisle with this aisle containment strategy, cold and hot air streams are separated. Cold aisle containment can save hundreds of thousands dollars per year and can greatly decrease your data center’s carbon footprint.

Hot Aisle Containment

Hot air containment provides a physical barrier that guides hot exhaust air flow back to the AC return of an IT infrastructure. Hot aisle containment increases the effectiveness of an IT infrastructure through various measures. Those benefits of hot aisle containment, include the elimination of hot and cold air mixing, the increase of cool capacity, and even improves data center cooling efficiency
