FYI - here are some links to a variety of 48-port commodity GigE switches,
that may be worth looking at (but as another poster indicated, these
might actually all be the same switch built by an OEM and just rebadged.
One can only really tell by opening one up and looking at the PCB and chips
that are inside.):
SMC8648T TigerSwitch

The SMC8748L2 I went with is here:

It's cheaper than the 8648T while apparently newer and with some "better"
specs. As I mentioned before, I'm decidedly skeptical and intend to test it
hard while I'm still well within the return period.
I've got my new switch in hand and I've done some preliminary testing. So
far, so good. Total bandwidth between 2 hosts connected to the switch was
quite comparable to that of the hosts being directly connected for just
about all the MTUs I tested (see
<http://www.duke.edu/~jlb17/tg3comp.png>). The hosts are centos 4.3 using
onboard BCM5704 NICs (tg3 driver), and I tested with netperf.
Now I just need to get it hooked up to more hosts and really have at it.
