I am not quite certain where the NFS server is in your setup ?
Is it a single server for the whole network ?
What was the disk arrangement on the NFS server(s) ?
The NFS server (at the top right of the original diagram) was
on a dedicated subnet on the back side of the LTSP servers, as
indicated on the prior post.
Each LTSP server had a dedicated interface for that subnet.
I considered, but did not add a dedicated link for each LTSP
server directly to the NFS server with no other hosts on that
network segment (simple enough to do - a cross-over cable and
a NIC port would do it)
On the NFS server, the /home export was in a separate spindle
series (raid-5) from the OS, and from a code content export
for the presentation tier.
A MySQL server is also in there at that installation along
with a backup rsync and tape server (weekly level 0 backups
and daily rsync backups), but these are out of scope for the
network diagram, as they sit behind the content server at the
top of the original diagram (which had another utility subnet
so that access to that data was also out of the packet stream
view of the clients).
