Is this RAID setup ok? 3 x 500GB drives...

Posted on 2011-10-31

My 'pre configured' IBM x3200 server has arrived. It has 3 x 500gb SATA drives. I asked for two drives to be mirrored with 1 hot spare.

However I don't think they have configured the Hot Spare as requested.

What do you think? Is it ok?

EDIT: they were suppose to update firmware as well. It doesn't look like that is the case with "2009" shown at the top.

    That sure looks like it's a Raid 5 array and not a raid 1 w/ spare.

    Is this an issue? Should I change it or leave it as it?

    If OS is not installed recreate the array as RAID5

    What level of RAID is it setup in now?

    Type = IME?

    I think they have done what you want to, but instead of using RAID 1 with hotspare, they are using IME (Integrated Mirroring Enhanced). This is also RAID technology but used by LSI and rarely known. Here is some info if you like to read,

    RAID 1E / RAID 10 with 3 disks is pretty well known, LSI have just given it a different name. Certainly better than RAID 5 both for performance, redundancy and rebuild speed so I'd stick with it unless you really want a hot spare. At least you've got disks which are suitable for a RAID controller although CCTL set to 7 seconds is a bit long in my opinion, the controller should cope with that rather than throw them out of the array when tyhey get a dodgy block.
