Why? Per my IBM tech rep (Tom Frein) and the tape guru (Bob Sommer), there is no legit reason not to put HSM into the VTS. Curious why your reps steered you away from that - maybe they figured they can make more money off you by selling you more 3592 native drives and tapes.

I'm putting both HSM incremental backups and ML2's into the VTS. I was considering going to native tape (3592's as well), but the biggest reason for putting HSM into the VTS is the fact that I can do away with the whole HSM Tapecopy process, since the VTS Copy export will duplex the tape in the background. That's gotta save a few MIPS on the Z/10 box!

As far as TMM - all of that is going into the VTS as well - why waste primary DASD for TMM? TMM was a good methodology prior to the advent of virtual tape - but now, it simply is much more cost effective to shoot the data to virtual tape.

You gotta upgrade that bad boy to a 3584/TS7700. It rocks!
