Sun Cluster 3.1 10/03 Concepts Guide

N*N (Scalable) Topology

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

The following figure illustrates an N*N configuration.
