Disadvantage:

•Must ensure that the failover cluster nodes have ample resources available to handle the additional workload.

Figure 1-3 shows an example of multiway failover configuration.

Figure 1-3. Example of a 4-Node Multiway Failover

Table 1-4 provides an example of a multiway failover configuration for the cluster shown in Figure 1-3. For each cluster resource group, the failover order in the Preferred Owners list outlines the order that you want that resource group to failover. In this example, node 1 owns cluster resource groups A, B, and C. If node 1 fails, the cluster resource groups A, B, and C will failover to cluster nodes 2, 4, and 3, respec- tively. The cluster resource groups on cluster nodes 2, 3, and 4 need to be configured similarly.

NOTE: When implementing this type of failover solution, failback should be config- ured to avoid performance degradation.

Cascading Failover

With Cascading failover, all running applications migrate from the failed node to the next preassigned cluster node. If you do not make a failover selection, cascading failover will be the default failover type. This type of failover provides the following features:
