Redundant Interconnects
To reduce potential disruptions of intracluster communication, use a redundant
path over which communication can continue if the primary path is disrupted.
Compaq recommends configuring the client LAN as a backup path for
intracluster communication. This provides a secondary path for the cluster
heartbeat in case the dedicated primary path for intracluster communications
fails. This is configured when installing the cluster software, or it can be added
later using the MSCS Cluster Administrator.
It is also important to provide a redundant path to the client LAN. This can be
done by using a second NIC as a hot standby for the primary client LAN NIC.
There are two ways to achieve this, and the method you choose is dependent
on your hardware. One way is through use of the Redundant NIC Utility
available on all Compaq 10/100 Fast Ethernet products. The other option is
through the use of the Network Fault Tolerance feature designed to operate
with the Compaq 10/100 Intel silicon-based NICs. These features allow two
NICs to be configured so that one is a hot backup for the other.
For detailed information about interconnect redundancy, refer to the Compaq
White Paper, “Increasing Availability of Cluster Communications in a
Windows NT Cluster,” available from the Compaq High Availability website

Cables
Three general categories of cables are used for Compaq ProLiant HA/F100
and HA/F200 clusters:
Server to Storage
Shortwave (multi-mode) fiber optic cables are used to connect the servers,
Fibre Channel storage hubs and FC-AL switches, and RA4000/4100s in a
Fibre Channel Arbitrated Loop configuration.
