Perc Raid 5/i

[Ernie Buford]

I asked a similar question earlier this month and got this
response:

http://lists.us.dell.com/pipermail/linux-poweredge/2007-March/029871.html

Since that time I've talked with a Dell TSR, who told me that
the PERC5i can do 2 RAID sets but not 3.  For example,
one could set up 2 RAID1 mirrors each composed of 2 disks.
Additional disks could be added to the other backplane slots
but would not participate in a 3rd RAID volume.  They could
be treated separately (no RAID) or incorporated into one of
no more than 2 existing RAID volumes.  I think it's common to
see a 2-disk mirror and a second RAID5 volume using 3 or 4
disks in the remaining backplane slots.

Someone correct if I'm wrong, but that's my understanding after
talking with the Dell rep.

Regards,
EB
