Sun Cluster Overview for Solaris OS

IP Network Multipathing

Clients make data requests to the cluster through the public network. Each Solaris host is connected to at least one public network through one or multiple public network adapters.

IP network multipathing enables a server to have multiple network ports connected to the same subnet. First, IP network multipathing software provides resilience from network adapter failure by detecting the failure or repair of a network adapter. The software then simultaneously switches the network address to and from the alternative adapter. When more than one network adapter is functional, IP network multipathing increases data throughput by spreading outbound packets across adapters.
