x86: N*N (Scalable)Topology

An N*N topology enables every shared storage device in the cluster to connect to every cluster node in the cluster. This topology enables highly available applications to fail over from one node to another without service degradation. When failover occurs, the new node can access the storage device by using a local path instead of the private interconnect.

The following figure illustrates an N*N configuration.
