Seems like any tuning you did for one I/O workload would be sub-optimal for
the other.
Are large transfer sizes still de riguer for LTO?

Well what it really boils down to is the following two things:
1) Do you really want to slow disk access for tape traffic
and
2) Is it a supported configuration. I've been told flat out by IBM that
it is NOT a supported configuration. So as much as I would like to give
my TSM server some space on the SAN, I don't have room for another HBA
(x335) and I'm not about to go unsupported for it.
