This article compares ten different containment strategies for data centers. Containment strategies discussed includes hot aisle containment, cold aisle containment, end aisle containment for both hot and cold aisles, hot and cold aisle containment, cabinet chimney containment, and other variation of containment strategies.  The model uses cabinet heat load of 3.8 kW to 34.5 kW. It concludes that hot aisle and cold aisle containment together offers the best performance both in terms of minimum inlet temperature and energy usage followed by cold aisle containment. It appears cold aisle containment provides the best value for money in these kinds of data modeled data centers.  The research for this article was done by Affiliated Engineers ( The article here is shared here only for education and non profit purposes.
