In a method of workload placement based upon capacity utilizations of a plurality of CRAC units, the provisioning of the plurality of CRAC units is determined and the zone of influence for each of the plurality of CRAC units is also determined based upon the provisioning of the plurality of CRAC units. It is determined whether a CRAC unit of the plurality of CRAC units is at least one of near failure or has failed. In addition, the workload is shifted from a zone of influence of at least one CRAC unit to a zone of influence of another of the plurality of CRAC units in response to a determination that a CRAC unit is at least one of near failure or has failed.
