Compaq Infortrend manual RCC Status Redundant Controller Communications Channel

RCC Status (Redundant Controller Communications Channel)

The item is display only, showing the current communications route.

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.
