How to build a 100,000-port Ethernet switch
Ever want bigger switches and the ability to run all hosts on a single subnet without performance degredation. So did some researchers who have devised a way to make layer 2 switchind scale well beyond current barriers.
University of California researchers are presenting a paper describing software that they say could make data center networks massively scalable. The researchers say their PortLand software will enable Layer 2 data center network fabrics scalable to 100,000 ports and beyond, and they even have a prototype running at the school’s Department of Computer Science and Engineering’s Jacobs School of Engineering.
This inclueds a system that uses psudo MAC addresses to remove almost all of the nasty broadcasts that choke current networks at this scale.

The question is: How do you rackmount a 42u switch? :)
