In a method for managing an infrastructure housing a plurality of disaggregated heat sources, in which a first disaggregated heat source has different heat dissipation characteristics as compared with a second disaggregated heat source, cooling requirements for the disaggregated heat sources are determined, in which the first disaggregated heat source and the second disaggregated heat source are to be positioned in separate homogeneous zones of the infrastructure. In addition, a respective available cooling resource is associated with the disaggregated heat sources based upon the determined cooling requirements of the disaggregated heat sources.
