100GbE and beyond for warehouse scale computing

As computation and storage continues to move from desktops to large internet services, computing platforms running such services are transforming into warehouse-scale computers. 100 Gigabit Ethernet and beyond will be instrumental in scaling the interconnection within and between these ubiquitous warehouse-scale computing infrastructures. In this paper, we describe the drivers for such interfaces and some methods of scaling Ethernet interfaces to speeds beyond 100GbE.
