Cabling the Private Network

The private (heartbeat) network is used for sharing cluster health and status
information between the cluster nodes. Each cluster node connects to the
private network through the second embedded NIC port on the server
module system board. The second NIC port connects to the internal
connections in the system chassis to the second Ethernet switch module or
the associated port in the corresponding Gigabit pass-through module. The
Gigabit Ethernet switch module or Gigabit pass-through module is
connected internally to the private network-configured Gigabit Ethernet
switch module in the private network or the corresponding port on the
corresponding Gigabit Ethernet pass-through module.
NOTE:
It is recommended that you configure the second NIC port on each server
module for the private network.
The Gigabit Ethernet pass-through module connectors correspond directly to
the server module number. For example, server module 2 is connected to port
2 on the Gigabit Ethernet pass-through module. To create a private network
between server module 2 and server module 4 (see Figure 1-1) using a Gigabit
pass-through module, connect a standard Ethernet cable to port 2 and port 4
on the Gigabit Ethernet pass-through module.
Table 2-2 provides a cable connection matrix for configuring the private
network using a Dell PowerConnect™ Ethernet switch or Gigabit Ethernet
pass-through modules in your PowerEdge server enclosure.
