If at all possible you may want to bypass L1 migration and go directly to
L2, even if it means keeping some data on L0 longer. SSM will kill your
mips.

I agree with many that a duplex VSM/VTS situation solves the DR problem
but that's capital outlay that probably won't happen. That leaves us
with one virtual box, and the DR "solutions" in that case are more
problematic.
I haven't yet compared the DASD cost so I will have toI accept at face

I'm in agreement with what Kees said - and TMM is *not* $0. After much
effort (years) one of my customers finally jumped from a large TMM
implementation to (duplexed) VTSs. The DASD cost of TMM was about 30% of
the installation - maybe more

We never went to VTS, we could implement partial TMM for $0. We
analyzed tape jobs that caused specific volser mounts, then TMM'ed the
small (Mb) tapes first. We have dropped from 100's of specific mounts
per day to 0-20. We still use about 50 3490 scratch tapes some days,
but they are backup ta
VTS disk may be cheaper than online disk, but the the total cost of the
VSM box with DASD may not be cheaper than what we need to go to TMM,
especially since that DASD is "free" - it's capacity we already own but
don't use. I appreciate the point, however, and we'll try to see if we
can figure

The virtual tape mount question in the SMF JWT thread prompted me to post
this:
We're thinking about moving off virtual tape, to Tape Mount Management.
We've been kicking the idea around because:
1. We think we have the DASD to accomodate an x-day buffer of user tape
2. All of our important b
