Towards sustainable and energy-efficient data centers: A Finnish viewpoint

Research output: ThesisLicenciate's thesis


In recent years, the rapid rates of growth in energy use have steered industry towards energy-efficient solutions. Thus, the energy efficiency of data centers and ICT in general have also recently received considerable attention. Furthermore, both economic and environmental benefits are seen to be attainable if proper actions are taken in these data centers. This thesis examines data center energy efficiency and sustainability focusing specifically on currently portrayed 'state-of-the-art' solutions to improve efficiency and sustainability. Trends and future prospects within the industry are also studied to better understand the evolving direction of the field. Another more specific focal point is the evaluation of these energy efficiency and sustainability related improvements against local conditions in Finland. The most important results include a comparison of various power distribution and cooling solutions with estimates of attainable improvement and figures of merit. Regarding sustainability, the viability of powering data centers with renewable energy sources is estimated and complemented with examples of achievable economic and environmental benefits.
