I have heard of quad-fast ethernet cards which can be inserted via one
PCI slot and it will be possible to provide 4 external IP connections
with it.
I would like to know whether there are any such cards for 8 external
interfaces i.e. something like octa-fast ethernet cards, available.
Does anybody have information on it?

what about using a single gigabit ethernet interface and assigning 8 ip
addresses?

What I would like to know about is the possibility of having 8
different physical IP interfaces, and not 8 virtual IP interfaces with
1 physical interface.
Anyway, thanks for the information.

I'm not sure one exists, but you could always install two qfes. Why do
specificially need physical interfaces?

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.

Use 2 * QFE or 2 * Quad Giga in a suitable PCI based machine. Unless
you find something with proprietary connectors, I don't think there is
the real-estate on the back of a PCI card for 8 ethernet ports. If you
do find one, pretty sure it'll be expensive!

FWIW the Linux HME (aka Happy Meal) driver also supports Sun QFE cards.
I have a couple of PCs running Linux with dual QFEs installed, no problems.
