Clients connect to the cluster through the public network interfaces.
You can set up cluster nodes in the cluster to include multiple public network interface cards that perform the following functions:
Allow a cluster node to be connected to multiple subnets
Provide public network availability by having interfaces acting as backups for one another (through IPMP)
If one of the adapters fails, IPMP software is called to fail over the defective interface to another adapter in the group. For more information about IPMP, see Chapter 2, About IPMP Administration, in Administering TCP/IP Networks, IPMP, and IP Tunnels in Oracle Solaris 11.2 .
No special hardware considerations relate to clustering for the public network interfaces.
