That sounds simple, but in a dense rack the practical effect is important: every extra kilowatt must be carried away by air or by another cooling medium before inlet temperatures climb into an unsafe range. When airflow is too low, heat lingers in the rack, server fans accelerate, noise and energy. Quantify heat flux, cooling tonnage, and volumetric airflow requirements.

Rack mount equipment generates heat as a result of the processes it completes; the amount of heat a piece of equipment dissipates is approximately equal to the total electrical power delivered to it. This heat is absorbed by the ambient air in the server, and removed by airflows generated by fans. Sealing the open gaps in server racks is a well-known best practice when implementing airflow management improvements in a data center.
