All the time. Most systems worth being called "servers" have multiple independent PCI busses. > I got an Abit KT7 mobo with 6 pci slots and expected to find > multiple pci busses, but my three scsi and ethernet controllers > seem to share the same bus. > > I'm interested in putting together an eight to twelve port 100 > Mbit router, and any way I slice it a single PCI bus comes up as a > hard limit pretty quickly.

If you're putting together your own system, try the ASUS CUR-DLS, which uses the ServerWorks ServerSet III LE chipset. It has dual independent PCI busses on it, with two 66MHz/64-bit PCI slots and five 33MHz/32-bit slots. Otherwise, most of the servers from the likes of Dell, IBM, Compaq, etc. all use multiple PCI busses. The Compaq ML530 I have here has no less than four independent PCI busses, and I use it as an 100Mbit*8-port router, among other things. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
