High-density equipment within data center infrastructure is becoming more common, and yet many data centers are not adequately equipped to handle the additional cooling requirements. Because of this, cooling issues such as recirculation and mixing of hot and cool air, as well as poorly controlled humidity are becoming more costly.
This white paper 
from Opengate defines cooling over-supply and the dangers of the mixing of cooling overprovision with hot exhaust air from IT equipment. Next, it provides examples for quantifying cool air bypass and hot air recirculation, and solutions to eliminate leakage and bypass while providing tools to report the actual cooling being demanded by the equipment. Lastly, it demonstrates these solutions through detailed examples of reclaiming stranded cooling.
One of the key aspects you will like are the peer reviewed case study data from ASHRAE which have been updated with CFD model analysis. These studies reveal more information and provide visual cues about best practice on ceiling grate return and other passive cooling methods.
Learn the ability to more closely match the cooling supply volume to IT consumption. Click here to download this white paper 
on the benefits of reclaiming the wasted cooling capacity which results from hot air leakage and cool air bypass.
