Could you please help me to explain what is the difference on the diagram I drew and the one you provided in which all 4 FC ports on the node will be used? What issues would it caused by using my diagram?
In the recommended configuration, there are 2 connections from each controller to each switch. So it utilizes all 4 ports=2 connection x2 switches on a single controller. So you will have redundant connection to the switch also.
