Use ACU to configure your array controller and add additional drives to an
existing configuration. ACU can also completely reconfigure your drive array.
Reconfiguring your drive array is considered a "data destructive" operation.
ACU warns you about destructive operations before it performs them.
The ACU graphical configuration utility is run from the operating system. Use
ACU to create RAID array sets and logical drives from the physical drives
installed in the storage enclosure. The ACU graphical configuration utility
allows the user to set RAID type and other important settings that can affect
the performance and fault-tolerant capabilities of the TaskSmart N2400
appliance.
With the TaskSmart N2400 appliance, you can increase storage capacity
without taking the server offline. Innovative features allow you to change your
array configuration as storage needs grow.
