Recently I upgraded from:
- 8286-41A
- Internal spinning drives hosted by IBM i to other partitions of IBM i.
- - 280G 19B1 15k
- - 1.7T 5933 10k
- VTL tape drive
- 8GB Fiber channel ports for VTL on a switch doing other additional work.
The 10k drives were all hosted to one partition. We'll call it the 10k partition.
I upgraded it to:
- 9105-41B
- NVMe on FlashSystem 7300 SAN
- Kept the same VTL
- 16GB Fiber channel switch dedicated for SAN and VTL.
There's a report BRMS has which shows you a summary of save durations and the tapes they used.
PRTRPTBRM TYPE(*CTLGRPSTAT) CTLGRP(DTFULL)
It looks like this on the formerly 10k partition:
So basically a save that used to take 10 hours and 33 minutes at 421GB/Hr now runs in one hour and 26 minutes at 3,222GB/hr.
