Green It. Data center efficiency assessment

Technology has become a vital element for all organizations and this growing significance has forced companies to have huge and solid IT structures. However, today IT developed into one of the biggest contributors to the global warming. Both for environmental and financial motives and to remain competitive, companies need to ensure that their information technology systems are managed in an environmentally friendly manner. In order to manage the IT systems adequately, all the elements of the system should be deeply and correctly evaluated and inefficiencies should be clearly determined. Metrics are extremely vital for this evaluation. This study aims to understand the role of Datacenters within the field of Green IT. They account for the most of the energy consumption within the IT facility, and have therefore a major impact on environment and costs. In this connection this paper will answer two main questions. First, which metrics need to be assessed to rate the efficiency of a Datacenter both qualitatively and quantitatively. Second, which are the most suitable tools to gather and process the necessary data for the metrics calculation. Eventually theoretical findings will be compared and analyzed with the industries best practices.
