Mirrored drives is one form of RAID. Do a search on RAID on the web.

Two controllers is fine, you put one set of drives on a controller and their Mirrored copies (set of drives) on the other controller. So if one controller goes down, you will still have access to the data.

Mirrored drives is = one form of RAID. Do a search on RAID on the web.

Two controllers is = fine, you put one set of drives on a controller and their Mirrored = copies (set of drives) on the other controller. So if one controller = goes down, you will still have access to the data.
