Lost track in the thread here.. would a Networker client connection get
confused under a simple setup (multiple independent NICS on the same LAN-
no trunking).  I would think the outbound NIC server name (despite being
in the client's servers file) might confuse a Networker save session;
ie.. a reply comes back from different server name than it was initiated
on?  Was that the point being made here?

Multiple NICs on the same LAN seems good from a central admin point of
view;  one could manually load balance backup traffic based on storage
node name (or backup server interface name ) without having to move clients
to a different backup LAN.
