Hi *SM'ers
I am looking into why our LTO1 / LTO2 performance is so terrible (50%
rated throughput on avg) during backup stgpools.
TSM 5.2.4
AIX 5.2
IBM 3584 library
LTO1 and LTO2 drives.
The drives hit their rated throughputs during LANFree backup.
We have 2 sites with the same devices, 3584
I can answer one of your questions easily. Yes, the many small files
does affect backup stg pool, and all TSM data movements. It will
definitely be slower to move 1000 300byte files than one 300K file
for instance. Certainly with LTO drives, that's what I have.
