Thanks for your reply.
What I want to do is straightforward in concept (perhaps difficult in
practice, though I doubt it).
I want to put two Gigabit Ethernet Cards in one Linux server -- and have each
card talk to half the Windows workstations in my place. In part, I'm looking
for a way to get more data in and out of my server (the storage part can
support it). Each workstation is running a video editing application and it's
looking for about 4 to 4.5 MB/sec of data. The data is time critical. It HAS to
arrive when needed, or the editing application stops. So far I'm doing okay with
just one network segment, but I think I can add a few additional workstations
if I split the network -- because my storage subsystem is capable of doing
well over 100 MB/sec -- and that's a lot more than I'm going to push down one
Gigabit Ethernet pipe.
In part, I want to configure the two Ethernet cards differently so that one
can talk to workstations that are optimized for "Gigabit Ethernet and Jumbo
Frames" and the other can talk to workstations that only have "normal Ethernet"
I'm NOT looking to get more data to a single workstation. I'm looking to get
the maximum number of workstations that can all receive the 4 to 4.5 MB/sec
that they need.
By the way, my Server hardware is:
3.06 Ghz single processor Xeon, 1 GB RAM, Intel Gigabit nics, fast RAID
arrays, two switches capable of supporting Jumbo Frames.
