HP ProLiant Cluster HA/F500 for Enterprise Virtual Array Setup and Installation Guide

Overview of the ProLiant Cluster HA/F500 for Enterprise Virtual Array
Figure 1-2: Cluster straight-cable configuration
A component failure in a cluster straight-cable configuration 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.
A switch or cable failure will be 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.
In all of the typical failures, interruptions to the user are minimal and in some cases
may not even be noticeable.
