| 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
