Optimal airflow is built into the structure. The front door’s 65% open perforation pattern, along with vented side panels, a removable top panel, and an open bottom, enables consistent front-to-rear cooling—ideal for hot-aisle/cold-aisle deployments. These design elements help servers and switches run efficiently, reduce thermal strain, and maintain peak performance during heavy workloads.
