Resilient Server Links Overview
Resilient server links add redundant function to your server
to protect against network disruption and data loss.
To use resilient links, you must install two or more 3Com
ATMLink NICs in your system. During the network driver
configuration procedure, at least one NIC must be designated
an active NIC. The standby NIC takes over when the link on a
designated active NIC port is lost.
Rules for Using Resilient Server Links
Resilient server links are established only among ATMLink NICs
installed in the same computer.
To make a resilient server link, at least two ATMLink NICs must
be installed in the same computer, and one of the NICs must
be an active NIC.
Active NICs and their standby NICs must be connected to
switches on the same ATM network.
Up to three standby NICs can be assigned to a single active NIC.
A single standby NIC can be assigned to as many as three
active NICs.
