Abstract:
Rack enclosures in which host servers are not just the cabinets but an integral part of the airflow system of data centers. The cold air supplied from the air conditioning units must freely pass through the rack enclosures without any obstructions. Any excessive restrictions for the airflow offered by the rack enclosures not only adversely affect the cooling performance of the servers but can also disturb the overall balance of the entire airflow system. Air is the main carrier of heat in the data center. Therefore, proper management of cold and hot air streams in the data center is crucial for maintaining the acceptable levels of inlet air temperatures to the servers. However, just following the best practices for the data center design without proper considerations to the rack enclosures design is not sufficient for obtaining the desired cooling performance of a data center.
