If you add static routes for each client telling the server which
interface to use for each individual client, then you could manually
assign clients to NICs.

That'd suck from a mgmt persepctive.

Netbackup doesn't know about these multi NIC configs...it hands it off
to the OS, and the OS send it to the IP segment which deals with
routing, etc....I'd imagine, by default, you'd get a bunch of
connections on one interface.

For Sun, I would recommend IT Multipath, if you want the cheap and easy
way of doing it.
