807 154 Optical DataCenter Networks A. Zeimpeki DTU Photonik, Technical University of Denmark INTRODUCTION The Data Centers compromise an integral part of the Information and Communication Technology (ICT) sector that is gaining significant interest nowadays. This trend follows the increasing traffic volume of the web applications, the advance of the social networking services and the cloud computing, and necessitates more powerful facilities to arise. As a consequence, the carbon emissions are increasing and the energy consumption is a parameter that should be taken into consideration. The topologies accompanied by the technologies that are deployed affect directly the DataCenters' energy footprint. PROJECT SCOPE The specific project focuses on the optical technologies that are deployed in the DataCenter, and part of the scope is the comparison between different topologies in terms of their power consumption. THEORY The optical interconnects are widely deployed in the DataCenters nowadays as, among other advantages, they are less power hungry devices. Furthermore, the deployed physical topologies between the hosts and the switches, is a parameter that significantly affects the power consumption of the DataCenter. The different topologies (hybrid and all-optical) are compared in the present project. M ETHODS Different topologies with various interconnection schemes have been theoretically investigated and then implemented on the SP Guru simulation tool. The total power consumption of each topology can be evaluated through the “bill of materials” outcome. COMMUNICATION POSTER IDEA MASTER THESIS
