The dual switch network design is widely used in the FC SAN environment.

Deploy two FC switches in a SAN environment to cross connect to the two controllers of the storage device

Each host requires 2 available FC ports, and connects the two ports to different switches

The host port and storage device port on the switch that need to communicate must be in the same zone

Although there are multiple paths, the dual-switch network only supports link redundancy and does not support load balancing
