RAID 10 could be the way to go...but you get only 50% of total capacity.
If you have storage cache (with write-back option) big enough, I would also
test RAID5 if the backup time is acceptable for your needs and estimated
future db growth.

I know this is an older, slower array but it's all I have to use for
backing up a 500-GB test OLAP
database.     My understanding is that the rated throughput is 75Mb/sec.
   I'm running
Oracle 9.2.0.6 on Solaris 9, Sunfire v1280.     I've been given 32 disks
in the array, roughly
1 terrabyte, and have been asked how I wanted them configured.     Due to
the slower speed
of the Magnitude, what would you suggest for configuring these disks?
One /backup
mount point, RAID 10, striped across all 32 disks?

Thanks,
