DL 385 Raid Configuration

[Cary Corse]

I've got a DL385 with 3 140gb disks on controller 2 using raid 5 and 2 72gb disks on controller 1 using raid 0+1.

There's currently an empty slot on controller 2. Is it possible to put another 140gb disk on controller 2 and use it as a failover for either of the two existing raid arrays?

Generally, what are the available raid options for this particular machine?

Thanks in advance

Hello Cary,

Yes, You may Add another controller to the sever; However, making it a HOT spare for a complete raid failover is not possible.

Raid 0, 1 0+1, 5.

Read : Raid 0, 1, 0+1, & 5.

Just to clarify. If I add a disk to the empty slot on controller 2 I can use it as a hotspare for the raid array already on that controller (raid 5), but I cannot use it as a hotspare for the array on controller 1 (raid 0+1). Is this correct?

No Cary,

A HDD can be assigned as a HOT Spare to a raid (A) only if its on the Same Controller(A).

Controller (A) will not See HDD Connected to Controller (B)
