A spare drive should have a minimum capacity that is equivalent
to the largest drive that it is expected to replace. If the capacity
of the spare is less than the capacity of the drive it is expected to
replace, the controller will not proceed with the failed drive

When the configuration consists of multiple enclosures, it is
suggested that you use the new firmware function, "Enclosure
Spare," instead of the "Global Spare," to avoid a spare drive
participating in the rebuild of drives in another enclosure.
