This paper presents a critical comparison of a virtualised data centre infrastructure and an infrastructure that consists of physical servers. The authors' investigation shows how virtualisation can better utilise the hardware and consequently reduces the power consumption and carbon emissions. The case study reports an extensive research phase to identify main reasons for data centre virtualisation. The data centre is then modelled, based on server information from one of the data centres at the University of Greenwich. They emulate a virtualised infrastructure to contrast against the physical infrastructure.
