It is important to recognize that as rack densities exceed 4 kW, 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 the 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 cooling system adjustments that can reduce overall cooling energy costs at any rack density.
This white paper by Chatsworth Products (CPI) examines how:
• Different environments and scenarios impact operating temperatures
• Implementing a complete containment system contributes to overall reduced cooling system energy costs in the data center
• Containment systems can help to prepare your site for an anticipated increase in rack density
