Rapid RAID Recovery
The Rapid Raid Recovery feature increases the speed with which a redundant
unit can be made redundant again when a rebuild is required. It can also
increase the speed of verification or initialization that may occur in the event
of an unclean shutdown.
Rapid RAID Recovery is possible because the firmware maps the unit, and
tracks the areas of the unit where write activity occurs. Then, if a rebuild,
initialization, or verify is required, the controller only has to address the active
areas. The fewer active areas, the faster the rebuild, initialize or verify.
Since the units are mapped out and tracked from the creation of the unit, this
feature can only be enabled during unit creation. Also, once disabled, it
cannot be re-enabled.
The more space is available on a unit, the more benefit you will see in the
event of a rebuild, if you enable Rapid RAID Recovery. If all of a unit’s
capacity is being used, you may not see reduction of rebuild speed when using
