Table 1-3 provides a N+1 failover configuration for the cluster shown in Figure 1-2. For 
each cluster resource group, the failover order in the Preferred Owners list provides 
the order that you want that resource group to failover. If that resource group or its 
cluster node fails, the cluster will try to fail that resource group to the first available 
node in the list. In this example, node 1 owns cluster resource group A, node 2 owns 
cluster resource group B, and node 3 owns cluster resource group C. Cluster 
resource groups A, B, or C would failover to cluster node 4, if cluster node 1, 2, or 3 
fails, respectively.

Multiway failover is an active

n

/active failover solution where running applications from 

a failed node migrate to multiple nodes in the cluster. This active

n

/active type of 

failover provides the following features:

Automatic failover and load-balancing between the cluster nodes.
