grinch843 Posted January 7, 2009 Share Posted January 7, 2009 Hi,I don't know much about raid stuff so I thought I'd start playing with it on a junker system I have and see what I come up with. Anyway, if you set up a raid and the controller fails, can you just replace the controller and the raid still be valid? Do you have to use the exact same controller or will any controller work so long as it supports the same raid type?Thanks,Grinch843.........

cluberti Posted January 7, 2009 Share Posted January 7, 2009 Depends on the controller and how it creates the arrays. More expensive cards store the data on the disks and on the array (and are battery-backed), most cheaper cards will write that data only on the disks and have no backup. However, in both scenarios, in general you will need at least the same type of card to recreate/restore the array, and in some cases (usually seen with older Adaptec/Promise cards) if the card itself dies, the array is not recoverable from the disks unless it was a mirrored array (like a RAID1).
