Network and Storage Planning
Note: Only one NIC per subnet can be configured. This limitation is required to prevent confusion as to which NIC to
bind a virtual IP address to when a failover package is started on a node or fails over. It is highly recommended that
'eth0' be configured as a dedicated heartbeat. See
port makes the heartbeat immune to heartbeat starvation due to high network traffic. To avoid subnet conflicts, use a
private subnet and IP address (e.g. 10.0.0.1) for the dedicated heartbeat, and direct connect the Ethernet CAT5
cross-over cable to the other node to eliminate the need for an Ethernet hub/switch that could fail. You may use an
additional port to provide redundant heartbeats in case of primary heartbeat failure.
