HA Cluster Server Graphical Cluster Administration Workstation
In addition to the system consoles described in the previous sections, a LAN-attached
cluster administration workstation is required. Two local area networks are required to
eliminate a single point of failure.
Base HA Heartbeat Connections
The primary heartbeat connections between two HA cluster servers are made through a
serial connection and the LAN connections. These connections are shown in the
following 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 following illustration shows an HA cluster server using the 8-Port Asynchronous PCI
Adapter and Ethernet connections.
