8 is kind of a stretch but I've used 5 before- on a spacecraft
simulator, the (in this case) PC w/ Linux. One out to the lab backbone,
2 onto for the spacecraft A and B bus (or more correctly network) for
tcpdump et al, 1 for the space link (w/ PC acting as ip forwarder for A
& B network) and 1 to hook up to another subnet for other related uses.
Hardware segregation of the networks was useful because several
different physical layers and speeds were under test.

An U10 or so with a couple qfe's would have been more convenient than
loading up the PC's pci bus with a pile of lanboards. Next one of these
I build, I'll probably try the dual qfe & Solaris route, adding a 6th
interface to take in port monitoring traffic from the switch. At
present I have a U1 w/ one qfe doing something similar.
