Trichotomic Search for Thermal-Aware Data Centre Workload Optimisation

Abstract

The power consumption of a data centre (DC) can be attributed to the power consumed by running the servers and the power consumed for cooling them. The challenge is to optimally balance IT and cooling power requirements, which demands the minimisation of a non-linear energy utilisation function. In this paper we propose a problem decomposition-based approach to tackle a non-linear energy utilisation function and successfully apply it to minimising the energy consumption of a DC.
