Read Aheads

We are running 9.1D on a 12-disk RAID 10 Array.. should Read Aheads or Adaptive Read Aheads be enabled on the RAID controller? Or should they be disabled?
 
I would enable them.

It probably won't matter much most of the time. But occasionally, like when you do a dump & load, it could be very helpful. Especially if you have organized your db using lots of dedicated storage areas.

BTW -- 9.1D is ancient and unsupported. You should upgrade to at least 9.1E04.
