I posted same question(s) on AS/400 Forum BBSN today. I have two existing
parity sets of 5 and 7 drives each(IOPs are 2748 and 6533 on a 720-2061). I
want to add 8 more drives (6713s). I believe that I can get full capacity
from additional drives by adding them to existing parity sets so that each
would have 10. Does this make sense? Current sets have parity spread across
4 drives. I've seen some parity sets on my other systems that have parity
spread across 8 drives. Is this determined by the system? For a 10 drive
parity set, what is the optimum setup? Is there a reason that I should keep
parity sets no larger than 8? I appreciate any suggestions.
