Server: M80 running AIX 4.3.3, 4GB RAM, 768MB ps
DiskStoragePool, Rlog, & Database on all on a
SAN via fibre channel connection.
TSM version: 4.1
This is a newly configured system. We are conducting
tests on it. When we tried to do a few backups by
themselves, they seemed to get done pretty fast.
However, when we had 4 migration processes and a
couple of backups going at the same time, everything
slowed down to a halt. According to my client, his
backup transfer speed was about 100MB per minute. Can
anyone give me some suggestions to improve the
performance? I have attached the 'topas' reading of
this server.
TIA
