RE: Want to BAARF - Recommendations for 10 36G Drive config

I figure you have disks set out so

Drive 1 + Drive 2 = OS
Drive 2 + Drive 3 = Two tablespaces
Drive 4 + 5 + 6   = Oracle Default Tablespaces. 

And you have bought 4 more disks.

I "theorize", like test this to infinity and beyond, that changing this to the following will improve IO performance.

Drive 1 + Drive 2 = OS
Drive 3 + Drive 4 = swap + archive logs
Drive 5 + Drive 6 (mirroring) Drive 7 + Drive 8 = oracle data files. 
Drive 9 + Drive 10 = redo logs. 

I.E. stick your data on raid 10,stick redo and archive on two separate mirror sets and separate swap from os.

At which point you will no doubt discover that your IO capacity was fine and it was the damn data that was the issue.
