Just an FYI for those evaluating options.
We switched from LTO3 SCSI drives in a 3573 L2U to LTO4 fiber (HHV2)
drives in a 3573 L4U. Still using LTO3 tapes.
Bulk of data is stream file data (improperly called IFS data).
Takes 4 tapes. Tape 1 starts out as *allusr and ends up starting stream
Tapes 2&3 are flat out all stream file data.
Tape 4 finishes up stream file data.
Tape 2 & 3 dropped from 1 hour, 59 minutes and 2 hours, 10 minutes to 1
hour 31 minutes and 1 hour 40 minutes.
