As rack densities exceed 4kW, traditional hot aisle/cold aisle configurations become less effective. Hot air recirculates over and through the cabinet causing hot spots, which is typically met with costly oversupply of cold air. You can reliably dissipate the heat in these racks by utilizing a containment system that effectively isolates hot air from cold air and directs hot exhaust airflow away from equipment and back to air handlers. More importantly, careful airflow management through the use of containment systems allows several cool system adjustments that can reduce overall cooling energy costs at any rack density.
Read this white paper by Chatsworth Products (CPI) to find out how implementing a complete containment system contributes to overall reduced cooling system energy costs in the data center and prepares your site for increased rack density.
