ABSTRACT
Green algorithms rely on virtualisation as a core technology that simultaneously executes full operating systems as guests within a single hardware node. The flexibility of cloud computing and its success as a business model involve that users with diverse workload requirements access the cloud. Modern approaches for energy-aware IT management rely on modelling of the power consumption of the current workloads that run within modern hardware architectures. Within the RenewIT project, a virtual machine manager (VMM) for Data Centre workload management has been developed to optimise the VMs placement in order to maximise the efficient usage of the resources while keeping the workload performance standards that are mandatory by the cloud users. The electrical distribution system of the Data Centre includes, among other equipment, switches, panels and distribution paths, UPSs and autonomous diesel generators for power backup in case of mains failure.
