I have not used RAID controller boards to date since I have relied on the built in RAID on the motherboards. Thanks to the informative message Byron, I realize the deficiencies of doing RAID 1 this way, especially now that the builtin is out of date with Kernel used by Centos.

I have 4 ATA drives that were configured in two pairs. I assume that I need a 3Wave controller that has 4 ports like the 7506-4LP...correct?

Do I need to install any software during the installation of Centos?
