Well, it depends on which model of SS III ...
We are using a SS II 3300XM coupled with a III 3300XM, and they work
Plus, they can be managed via www. You can check bandwidth utilization,
errors, and all the configs both for a single port and for the all switch,
from a simple web interface.

Btw, we have a 1 server + 21 nodes beo, with NFS mounted users dir from
the server and PVFS between the nodes. We are running Monte-Carlo, fft and
home made protein folding cod (primarily, but we also sometimes "test the
cluster" :) with mpi-POVRay...) and we can go up to all the 22 nodes
almost without problems.

Hope this helps,
