Zoning w/ node pair vs zoning all nodes for 4 node 8440

Can someone explain to me which zoning practice is ideal for a 4 node system: Zoning to node pairs vs zoning to all nodes? Assume we are zoning to a host with 2 HBA Ports

For example, zoning to node pair would look like this:

Host group1 : Fab A ( 0:0:1, 1:0:1) Fab B ( 0:0:2, 1:0:2)

Host Group 2: Fab A (2:0:1, 3:0:1) Fab B (2:0:2, 3:0:2)

Vs

Zoning to all nodes like this:

Host group1 : Fab A ( 0:0:1, 1:0:1) Fab B ( 2:0:2, 3:0:2)

Host Group 2: Fab A (2:0:1, 3:0:1) Fab B (0:0:2, 1:0:2)

 

From my understanding zoning to node pairs w/ 4 node systems can have load saturation on a node pair while having resources available on the other node pair.

Yes, exactly.
