Setting Up a Public Interconnect

Redundant Interconnect

It is possible—but not recommended—to use a public network as your
dedicated interconnect path. To set up a public Ethernet interconnect, connect
the Ethernet cards, hub, and cables as you would in a nonclustered
environment. Then configure the Ethernet cards for both network clients and
for the cluster interconnect.
IMPORTANT: Using a public network as your dedicated interconnect path is not
recommended because it represents a potential single point of failure for cluster
communication.
NOTE: ServerNet is designed to be used only as a private or dedicated interconnect. It
cannot be used as a public interconnect.
MSCS allows you to configure any certified network card as a possible path
for intracluster communication. If you are employing a dedicated interconnect,
use MSCS to configure your LAN network cards to serve as a backup for your
interconnect.
See the "Recommended Cluster Communication Strategy" section in
Chapter 2 of this guide for more information about setting up redundancy for
intracluster and cluster-to-LAN communication.
