If you look at the entirety of my original post, I mention RAID 10 (1+0). By default, the T3 works at RAID5, but it can be configured in other ways.

Do you recall and Oracle documents or URLs expressing the opinion with which you just replied? It would be very helpful in my meeting in a few hours. Received on Thu Sep 18 2003 - 06:38:54 CDT
