3-12 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Setting Up a Public 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. Redundant 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.
