  • 2 RHEL nodes, which will be used to create the cluster. In this example, the nodes used are z1.example.com and z2.example.com.
  • Network switches for the private network. We recommend but do not require a private network for communication among the cluster nodes and other cluster hardware such as network power switches and Fibre Channel switches.
  • A fencing device for each node of the cluster. This example uses two ports of the APC power switch with a host name of zapc.example.com.
