A system and method for designing aspects of a cooling system for a data center is provided. A method is provided including computing cooling redundancy at each rack position in a data center, in real time. The redundancy can be reported using the traditional N+1, N+2, etc. notation, where N is the number of coolers required to meet the primary cooling load type specification. The redundancy can also be reported in terms of a Cooling Reliability Index (CRI) which also takes into account the inherent availability of the specific cooling units in the design.
