I believe what mark is talking about sounds a lot like the Sun Sparc Cluster I, a product I designed and built back in 1992. It was an NFS server that used a switch to be able to talk to lots and lots of different IP subnets without going through a router. The hack I put into the swith is what is now known as "VLANS".
I believe there are some papers about it on my old home page at

I don't have Mark's address, if someone who does could pass this on, I'd appreciate it.

: sun already sells a multi port card that supports trunking i.e. you can : combine 4 100baseT cards for 800mbs fullduplex operation but I don't think : linux is able to do such a thing yet.... it would be nice though. : : --Jauder : : On Thu, 12 Mar 1998, Mark Spencer wrote: : : > <LONG VERSION> : > Dunno if this can already be done, but this would be cool to do... : > Imagine if you will a real life scenerio I saw at a company today: Lots : > of machines on one IP subnet all trying to connect to a single server. : > The server is on a switch, and the switches are themselves hooked : > together.
