Clients don't have to be upgraded. It's transparent to them.

Really looking forward to DAOS. Have to get all those clients upgraded
first.

You don't need to do anything different as long as your disk drives aren't
already experiencing usage/utilization problems. IIRC, Walter said you'll
see about a 3% hit by starting transaction logging, but you'll probably
recoup that once you setup DAOS and see the reduced I/O overhead that it
will likely bring.

Went to an IBM & Partner intro to 8.5 last week. One of the new options
we may look at requires transaction logging be fired up. Most of the
time
when I hear about transaction logging it makes me think of something
primarily run in a lab or on a test machine. Because, they mention
keeping your data on one drive and your transaction logs on another
drive.
Well, my machine has ninety disk drives. All Raid 5 protected. Does
it
really make sense to put the transaction log on dedicated disk? On the
i
that would involve Auxiliary Storage Pools or ASPs. In theory I could
have two ASPs: Main data in one and transaction logging in the other. I
can't imagine it would take more than a few 70gb disks to do transaction
logging.
Raid sets smaller than 4 drives are known to have serious performance
implications. Technically you can do a 3 drive raid set, but unless the
customer is just migrating from a S/36 they will notice the performance
hit versus a 4 drive (or more) set.

Is this separate disk stuff recommended on a "real" os?
Do I need a full RAID set in an ASP?
