Having enough cooling capacity for a specific space does not guarantee that the load will be cooled properly. Getting the right amount of “cool” air to the load is very critical. Incorporating best practices in airflow management is a must, such as hot aisle/cold aisle, blanking panels in racks, between racks and under racks, and sealing cable cut-outs just to name a few. Once you have done all of these, then you can look at improving your efficiency by doing things such as raising operating temperatures, enclosing the cold aisle to separate the air streams (this white paper gives a good explanation of this process: http://bit.ly/c3CgUE) and using supplemental cooling for high density areas.
