Secondary Controller RS-232
This is an option reserved for debug purposes. When enabled, you can
access the secondary controller through its serial port. When combined into
a redundant controller system, only status display is available through the
terminal session with a secondary controller. No configuration change can
be done through a secondary controller.

Remote Redundant Controller
This is an advanced option reserved for system integrators.
Cache Synchronization on Write-Through
If your redundant controller system is not operating with Write-back
caching, you may disable the synchronized cache communications. You
system can be spared of the efforts duplicating and transferring data
between partner controllers. This tremendously increases array performance
but you risk losing cached data if power outage or controller failure should
occur.
