Figure 1-2: Cluster straight-cable configuration
A component failure in this cluster will result in a failover to a second component,
and the user can continue using the cluster. Some typical failures and responses in
this configuration are:
• A server failure will cause Microsoft cluster software to fail over to the
other node.
• An FCA failure will cause subsequent data requests intended for the failed
adapter to be routed over the second adapter.
• Switch or cable failure is detected as an FCA failure, and a failover to the second
adapter will occur.
• A controller failure will cause the second controller to take over for the failed
controller. Secure Path will then route the data requests to the second controller.
