I have now read way too much on RAID.
The most significant item that I read is that the hardware RAID controller on the ASUS motherboards, as is most motherboards, is in reality a software RAID solution. I have also found that the motherboard solution is primarily for Windows operating solutions.
I also read up on LVM. I have determined that I will use LVM for the file system of the server. I attempted in install the server software on one of the drives of the RAID array and the installation completed successfully. Unfortunately, when I rebooted the machine, grub hung with Error 2.
Tomorrow I will turn off RAID in the BIOS and reinstall the server software with LVM.
