1. A computer implemented method for thermal relationships based workload planning in a data processing environment, the computer implemented method comprising:

  • determining, for a data processing system having a cooling correspondence with a cooling unit in the data processing environment, a fraction of an additional heat generation potential of the data processing system that the cooling unit will have to dissipate, wherein the additional heat generation potential of the data processing system is an amount of heat, in addition to a present amount of heat generated by the data processing system, that the data processing system will generate when the data processing system is operated at a predetermined capacity level, and wherein the cooling correspondence is a thermal relationship between the data processing system and the cooling unit representing a fraction of a total cooling used by the data processing system that is provided from the cooling unit;

    computing, using the fraction and a cooling capacity utilization of the cooling unit at a given time, an expected cooling capacity utilization; and

    adjusting a workload on the data processing system, responsive to the expected cooling capacity utilization exceeding a threshold.
