I read this question differently than others who responded.  In case
the question related to SSO, recent NetBackup versions (6.5 and higher
IIRC) reduced the traffic among media servers sharing a drive, making
it practical to have more media servers sharing more drives reliably.
A dozen media servers sharing four LTO4s certainly works; I don't know
what the practical maximum would be.

Note:  the more of your media servers that are Windows, the more
problems you will have (RSM, HBA drivers, network comms for SSO, ...).
