Mark,

If I were to set up a VTL, I'd personally go with option 1.  Option 1
allows all the storage nodes to see all the tapes, so if you have to take down a
storage node for any reason, the rest can fill in and things still work.  Option
2 pays too much money to EMC for DDS licenses.  Option 3, prevents you from
migrating workload between storage nodes as you move forward.

That is my opinion -- and I don't use VTL, so it's worth every cent you
paid for it ;-)
