Public Network Interfaces

Clients connect to the cluster through the public network interfaces. Each network adapter card can connect to one or more public networks, depending on whether the card has multiple hardware interfaces. You can set up nodes to include multiple public network interface cards configured so that one card is active and others operate as backups. A subsystem of the Sun Cluster software called "Public Network Management" (PNM) monitors the active interface. If the active adapter fails, Network Adapter Failover (NAFO) software is called to fail over the interface to one of the backup adapters.

No special hardware considerations relate to clustering for the public network interfaces.
