Energy and Exergy-Aware Workload Assignment for Air-Cooled Data Centers

The energy required to cool a data center (DC) depends on both thermal and workload management. Although existing energy- and temperature-aware workload assignment approaches reduce operational expenditure by minimizing cooling energy consumption, they do not address the loss of available cooling capacity (i.e., loss of thermodynamic exergy) due to unavoidable system inefficiencies. By quantifying the exergy efficiency, the actual cooling COP …
