My thought's exactly JR.
 
I'm thinking folks either have VTLs where they are licensing from the
vendor on a "per virtual drive" basis, OR, they are licensing Netbackup
on a (old) per drive, rather than (new) per TB of usable disk basis, so
want to avoid the licensing cost of adding more virtual drives......that
was on of my primary criteria in selecting a VTL....I want to be able to
create as many virtual drives as I want.
 
I currently have 20 physical drives, and run various multiplex levels
for different STUs, depending on the type of backup, in order to
maintain sufficient data flow to stream the drives, but when the VTL
comes into play, I want MPX=1, so I'll be configuring upwards of 20
virtual drives per media server.

        Agreed.  Coming from an environment where we are "afraid" of
multiplexing everything due to those image's importability (or lack
thereof), the fact that we cannot demux quick enough has us handcuffed a
little.
         
        Just a question, what's the rationale on mpx'ing to your VTL's?
         
        Cheers,
        Jon
