6.1. Linux FailSafe Example with Three-Node Cluster

The following illustration shows a three-node Linux FailSafe cluster. This configuration consists of a pool containing nodes N1, N2, N3, and N4. Nodes N1, N2, and N3 make up the Linux FailSafe cluster. The nodes in this cluster share disks, and are connected to a serial port multiplexer, which is also connected to the private control network.
