LaserVault also requires separate FC connections for each virtual drive in the library.

This is NOT a blanket statement, rather it is yet another "It Depends"!

For Cybernetics and also for Data Domain it is a true statement.

For ETI SPHiNX it is NOT a true statement.

For other vendors "It could go either way."

Bottom line is to discuss with your vendor if purchasing because you
don't want to find out you have insufficient ports!!

One big difference between a VTL and one of those IBM 3xxx series physical libraries with multiple drives is that the VTL uses a single port on the NPIV capable switch even if it has multiple tape drives configured in it. The physical library has you run a separate cable from each drive in the library to the NPIV switch.
