Base HA - 7017 Cluster Server Heartbeat Connections
The primary heartbeat connections between two HA - 7017 Cluster Servers are made
through a serial connection and the LAN connections. These connections are shown in
the illustration.
The serial connection is made using an 8-Port Asynchronous PCI Adapter or an
optional 128-Port Asynchronous PCI Adapter. The LAN connections are made using a
pair of Ethernet, FDDI, Token Ring, or ATM connections.
The figure below shows an HA cluster server using the 8-Port Asynchronous PCI
