Question about Multiplexing and Fragment Size
I've been reading up on multiplexing and fragment size tuning. Specificaly from the NBU 7.1 Perfromance Tuning Guide. I understand that Fragment size should be adjusted to improve restore performance when restoring only small amount of files on multiplexed tapes.
I'm curious on why I would reduce the fragment size drastically from default when the fast locate feature is enabled on the tape drive? Would it be beneficial to go to 500GB fragment size? I've seen some recommendations of 10GB or 50GB fragment size but I feel like that may be too small.
