* The dual active-active controller system enables a controller to take over the pool disk resources
and access the data upon the failure of the other controller. Takeovers can be initiated manually or be set
up with the automatic system failover protection (please refer to the software user manual).
**Storage Controller A (or B) has taken over the system. Storage Controller B (or A) has been
recovered and it is ready to resume data service. Giveback can be initiated manually or be set up with
automatic failback after system recovers (please refer to the software user manual).

Storage Controllers

With the dual-controller configuration, the controller on the left is Storage Controller A (SCA) and the
right is Storage B (SCB), as named in the QES, when viewed from the rear of the system. The dual-
controller configuration offers redundant access to disk storage. In the case of a controller or an I/O
path failure, the redundant controller will continue to provide access to disk drives.
for about 5 seconds. It provides the same function as
the Power on and Shut Down function in the High
Availability app on QES.
