Abstract: Described is a rack-switch including a rack and a plurality of blade server chassis within the rack. Each blade server chassis has a plurality of server blades in communication with at least one switch. Each switch includes a plurality of external ports. At least two of the external ports of each switch are inter-switch link (ISL) ports. The rack-switch also includes a plurality of inter-switch links. Each inter-switch link electrically connects one ISL port of one of the switches to one ISL port of another of the switches. The plurality of inter-switch links interconnects the switches such that the switches are daisy chained in a loop. The inter-switch links convey Ethernet packets representing server-to-server communications between server blades of different blade server chassis.
