Containment is relevant for data centers of all sizes, from small installations to hyperscale facilities. As power densities increase, separating hot and cold air becomes essential to maintain predictable cooling performance and energy efficiency. 

Even single racks can benefit from containment approaches, such as vertical exhaust ducts or localized airflow management solutions, that provide targeted containment without requiring a full-aisle enclosure. 

Regardless of scale, successful deployment requires a clear understanding of the air entering your IT equipment.
