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 package is started on a node or fails over. It is highly
recommended that one of the NICs (internal 10/100 is recommended) be configured as a dedicated
heartbeat. Having a heartbeat on a dedicated network 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. (See "Connect the Network
Ports" on page 36.)
