Chapter 5 Configuring Network Interfaces 105
About Redundant Network Interfaces
You can configure your system with redundant network interfaces to provide a
highly available network connection. Such a configuration relies on special Solaris
software features to detect a failed or failing network interface and automatically
switch all network traffic over to the redundant interface. This capability is known
as automatic failover.
To set up redundant network interfaces, you can install a pair of identical PCI
network interface cards, or add a single card that provides an interface identical to
one of the on-board Ethernet interfaces. You can enable automatic failover between
the two interfaces using the IP Network Multipathing feature of the Solaris
operating environment. For additional details, see “About Multipathing Software”
on page 148.
Note –
To help maximize system availability, make sure that any redundant
network interfaces reside on separate PCI buses, supported by separate PCI bridges.
For additional details, see “About PCI Cards and Buses” on page 68.
