Our DB is on RAID5 Disks, we do not use DBCOPY, but logging instead.

Just as all the documentation recommends we have set up our db volumes to
have
DBCOPY volumes for mirroring. Because these volume, both the dbase and the
dbcopies are on RAID 1 disk I question the necessity of the DBCOPY volumes.
I do not have an option to drop the RAID 1 disk and the controller of the
disk
is smart enough to direct reads from either disk depending on load
balancing
requirements therefore negating the read benifits of software mirroring.
I would be interested in your opinions on this theory especially if I am
missing a key benefit of the software mirroring.
