In the past, when a cooling problem existed, the solution was merely buying another CRAC unit and sticking it on the raised floor. 

In today's superheated IT equipment, that method will not solve all problems. Today, the problem might be resolved by a variety of methods. Spreading out the heat loads might be one. Perhaps loading cabinets half full is more prudent than completely full. Sometimes space is the best solution to a cooling problem.

If that is not an option, perhaps a standard upflow CRAC ducted over to the potential hot spots is a solution. Or maybe a ducted return system is sufficient. Getting the cold air to the places you want it, and keeping the hot air out of those same places is the key.

If those do not work, then perhaps high-density cooling is the answer. This may include in-row cooling, or supplemental cooling or heat rejection above the racks. There are a number of products by a number of manufacturers that provide good solutions.
