Multiple NICs on the source and target

With any source configuration, additional NICs on the target increases flexibility and control. Secondary target NICs can

assume the traffic from a failed source NIC while normal target traffic can continue to use the primary target NIC. Multiple

sources can be directed to specific NICs.

For example, a single target containing three NICs monitors three source machines located on different subnets. Each source

has one NIC attached to a different subnet. Each source's IP address is configured to be assumed by the target NIC on the

appropriate subnet.

NOTE: When using multiple subnets, the location of the source and target can be critical. If the source and target are

located on different subnets, users cannot access the source machine name and IP address on the target’s

subnet after failover because of routing conflicts. To avoid this situation, keep the source and target on the

same subnet or use a virtual private network.
