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 tapes and only mounted again for restore. We moved SMF and a few select system tasks to the 3494/3590, but mostly HSM is the only user of the 3590's. Our 3490 tape library was 16,000 at it's peak about 2000 but is about 4500 now.
