We have a couple of 3584s with ALMS, and though we use TSM to share the
library among 9 TSM instances, I still find the VIO features of the 3584 to
be handy.  Having up to 255 virtual I/O slots can be nice when adding tapes
to the library.  When switching from one generation of drives and media to
another, it is nice to be able to flexibly shift slots from the older
generation to the new one.  Overall, the virtualization of the library is a
very nice thing.  Is is required?  No, not at all.  But it's nice!

Wanda,
Thank you, that was very helpful.

Perhaps ALMS is intended primarily for non-TSM applications.  It
sounds like logical libraries are superfluous if TSM control points
are used correctly.  If I'm going too far with that, please let me know.

Best wishes,
Keith Arbogast
