Hi all,

This has probably been beaten to death in a FAQ somewheres, but I can't seem
to find it.

For an 8.1.7 DB on Solaris8, I think I've got my file placement down except
for the control files.  As far as drives left unoccupied, I've got 2+2
(four) 36GB 10K (15K, maybe?) SCSIs.  All 4 drives are in the same physical
box, but each 2 sets of drives has separate controllers and power.

So, considering performance and reliability, where do I put the control file
or files?  Here are the options as I see it:

1)  Stripe each set of 2 drives.  Have Oracle put a CF on each.
2)  Mirror each drive from set A onto a drive on set B.  Have Oracle put a
CF on each.
3)  Stripe set A, mirror onto set B.  Have Oracle put 1 CF on the set.
-or-

If I bring in the 6-way stripe (mirrored to another 6-way) we're using for
the datafiles:

4)  Stripe set A, mirror onto set B.  Have Oracle put 1 CF on this set, and
another on the 6-way.
5)  Stripe all 4 together (no mirror).  Have Oracle put 1 CF on this set,
and another on the 6-way.

Of course, I'm limiting this to only 2 CFs -- that's not set in stone, but
with all the mirroring going on between all these controllers and power
supplies, I didn't see a need to triple the CF count.  Also, I have no idea
what kind of load this DB will take.  It'll be driven by a vendor's product,
and I don't know how big the DB is yet (but I have to create it!), how many
will hit it concurrently, etc.  <sigh>

Any advice is welcome.  Thanks!  :)
