Takeover configuration with dedicated and standby interfaces

With two NICs on each node, one can provide a dedicated interface and the other can act as a standby interface.

In the following configuration illustration, you use two NICs for each interface, one on each storage system. One NIC acts as a dedicated interface and the other acts as a standby interface.

If Node 1 fails, interface e0 on Node 1 stops functioning, but e0 on Node 2 substitutes for the failed interface and handles the Node 1 network connection with the 230 network.

If Node 2 fails, e1 on Node 2 stops functioning, but e1 on Node 1 substitutes for the failed interface and handles the Node 2 network connection with the 230 network.
