Infortrend RAID Controller Manual

8-6
Logical Drive Preferences:
After member drives are selected, a list of selections will appear.
Maximum Drive Capacity:
As a rule, a logical drive should be composed of drives with the same
capacity. A logical drive can only use the capacity of each drive up to
the maximum capacity of the smallest drive.
Assign Spare Drives:
You can add a spare drive from the list of unused drives. The spare
chosen here is a Local spare and will automatically replace any failed
drive in the event of drive failure. The controller will then rebuild
data onto the replacement drive.
A logical drive composed in a none-redundancy RAID level (NRAID
or RAID 0) does not support spare drive rebuild.
Logical Drive Assignments:
If you use two controllers for the redundant configuration, a logical
drive can be assigned to either of the controllers to balance workload.
The default is primary controller, press [ESC] if change is not
preferred. Logical drive assignment can be changed any time later.
