We are in the process of installing = new disks and upgrading our software and I was looking for some opinions = and/or facts.
 We are upgrading to AIX 4.3.3 and = Oracle 8.1.6 on a basically OLTP system. We will also be adding SSA disks with = a RAID0+1 configuration.
 My questions are : In RAID5 it is recomended to put the = redo logs on raw devices, now with RAID0+1 should I do this? Is the performance or RAID0+1 good = enough so as not to effect my redo logs?         Are there any other files (ie, : rbs,archive logs,temp, = etc) that I
 should consider not putting on = RAID0+1 also, 
         that is if the concensus is to leave them off?
