It depends on the size of the datastores and number of nodes. If you need
to add more storage for your images or balance I/O, you will need to add
more NFS servers. So each datastore (from a different shared FS server)
will have its own mount point.

For small size setups your configuration is simpler and it should work.

That is because only the nodes operate with it. No need to mount it in the
FE anywhere.
