Pathways to servers of the future

Computing server infrastructures are reflecting the backbone of modern information technology. The future architecture of servers is driven by three major factors. First, performance has to increase from a computational as weIl as from a data processing perspective. Second, energy consumption has to be substantially reduced. Energy efficiency is then a main driver for the third goal of reducing the total cost of ownership. In this extended abstract we will outline the challenges with respect to future server infrastructures as weIl as address so me of the open problems with respect to energy efficiency.
