From: | | Kyle Prescott |
Shelly,
We usually run about 3 sessions per amp (CLUSTER ARCHIVE AND RESTORE) on a restore for a 24-amp system to be optimal. I talked with the
ARC guys at partners. They said after about 30-50 sessions, performance may begin to recieve deminishing returns. ARCMAIN won't let you do
more than 1 per AMP on an ALL-AMP archive anyway. So 2 sessions per amp on a 12-amp system (restore/copy) could probably be pushed to 3.
That would give you 36 sessions which fell within their recomended range.
Regards,
Kyle
