[clue-tech] RAID no. of disks

I try to keep my mouth shut.  Cruise over to comp.databases.informix and
google for "Raid 5 Art Kagel".

I know that things like RAID 5 need at least 3 disks, and can lose 1
disk.  The biggest RAID sets I set up are RAID 6 with 12 disks, and
honestly that's pushing it a bit for fault tolerance.  But it does seem
to work.

Does anyone on the list know if there is an upper limit to the number of
disks?  I am sure there must be, as the parity can't possibly be rebuilt
from just using one extra drive, if you have 1000 data drives, for
example.  I'm sure there has to be a tradeoff somewhere, like if I have
1000 drives, I'm not getting a capacity of 999 drives, maybe more like
900 drives.
