The ProLiant ML350 cluster configuration uses the CNM feature of the SCO
UnixWare 7 NonStop Clusters software. CNM replicates data between disk
drives in the two nodes. Figure 1-2 illustrates the mirrored internal disk drives.
Because the replicated, or mirrored, data is kept synchronized between the two
servers, current data is available even if one of the nodes fails.
