If you already have a 3494, going to a 3584 is NOT and upgrade.
IBM has never claimed that the 3584/LTO solution is as robust as the
3494/3590 solution.

My PERSONAL opinion is that If you have a LOW ACTIVITY TSM environment:
meaning not a lot of tape mounts per day, not a lot of reclaim activity

Then the  LTO solution is fine and much less expensive.

If you require a high-availability/high activity environment:
meaning reclaim activity around the clock, LOTS of tape mounts per day, HSM
function

Then you should stick with IBM 3590/3592 or STK 9840's, which take more of a
beating.

My opinion, and nobody elses.

I have a 3494 with Magstar tapes 3590  and I would like to use a 3584 with
LTO tapes . What do you think about this choice (fiability,reliability..) .

Kind regards
