Thee IP settings in the above example are configured for added iSCSI redundancy. The IP address for NAS
however remains the same since NAS is configured for one controller only. It is irrelevant for NAS if the controllers
are Active-Active or Active-Standby.

The final example uses two switches or routers to create an additional layer of redundancy for high availability.
Using this cabling method, it is necessary to trunk all four ports on each controller.
