Active/Active Failover Mode (Performance)
The CR3500 Configuration Utility (Controller Properties) allows you to
specify the two Host I/O Channels supported by the controller as either active
or passive. The table below explains how the Host I/O Channel settings
determine the failover method. If the system is configured with two CR3500
Controllers, Host I/O Channel 0 is set to Active and Host I/O Channel 1 is set
to Passive for Controller 1 and oppositely for Controller 2, then the Failover
Mode is Performance.
