A storage system that has blades and fabric modules connects to a customer legacy network that has a first, active switch and a second, passive switch. A first link aggregation group (LAG) is configured active and includes ports of the first, active switch that connect via links to the first and second fabric modules of the storage system. A second LAG is configured passive and includes ports of the second, passive switch that connect via links to the first and second fabric modules. A multi-chassis link aggregation group (MLAG, MCLAG or MC-LAG) is configured and includes ports of the first and second fabric modules that connect via links to the first and second switches.
