Well, not exactly. As is mentioned by others, using this for offsite pool
reclamation with collocated primary tape pools will minimize the tape
volume contention (but may increase the number of tape mounts).

But hey! if you run any three tape processes, and they all need data off
the same volume, there's going to be contention no matter how you slice
it.
