You _could_ do that but unless you have some wicked NAS with 10GBps etc
etc I wouldn't.

Use 1 media server and one disk storage unit.

If you want you technically could:

media_server1:/nas1/media_server1
media_server2:/nas1/media_server2

And use separate directories for each media server's DSU but that would
KILL performance, it is bad enough you have to use it over NFS right?

client <-> media server ----------.

                                  NAS

That is if the NAS is directly connected, if its not...

Yes it adds overhead and it depends on your network topology.
