I'm going in the direction of the 3592 upgrade for my 3494.  I have an LTO1
w/2 drives for an offsite copy pool and I've had more problems with it than
the 3590 drives in my 3494 primary storage pool.  I believe the 3592
technology to be much more stable and tested than the LTO models.  I don't
think IBM will phase out the 3592 line because it's there cash cow.  You pay
$30k for a 3592 or $10k for an LTO why would you phase out your money maker.
Besides large mainframe environments highly use 3590 technology.  Although I
do believe LTO storage capacity will exceed 3592 drives in the near future
and upgrades in capacity to 3592 line will be slower than those for LTO.

Ah.  Careful with this statement.  It does fit, however, you need a frame
conversion, library manager upgrade, and 3592's and 3590's can't coexist in
the same frame.

We may not *convert*, but we may move our 3590's out of our L unit, upgrade
it, and move in a couple of these babies.  They do look nice, but I still
hate
the thought of the dataloss, if one cart gets damaged or fails.  ooooh.
