I just kick off a migration on my newly configured server,
and I am only seeing 0.4MB/sec per 3590 drive!? I know
these drives are capable of 9MB/sec from my SSA pools.
I am collocating, but let's be real.
Question is, what tuning parameters effect the migration
from disk to tape? (I know I need the tuning class)
SERVER: ADSM ver 3.1
CPU: R50 .5 GB RAM 2-way procs
DISK 300 GB SSA
