For the last few years, Oracle has recommended using a single RAID 10
array. They call it the SAME methodology (Stripe And Mirror
Everything). The thinking is that with today's caching controllers and
fast disks, you'll get a better I/O balance with a single RAID 10 array
than you would spending a lot of time trying to analyze I/O and moving
datafiles around. There's a white paper about it on OTN or Metalink.
We've been using this method on Dell servers and it works well.
