Dell Unity 400 - Zoning

Hi Everyone,

Can someone help me what's the difference on the zoning practice below for dell unity storages:

zone1
server1_hba1
spa0

zone2
server1_hba1
spa1

zone3
server1_hba1
spb0

zone4
server1_hba1
spb1

zone5
server1_hba1
spa0
spa1
spb0
sbp1

 

Assuming that zone above will be created to a single switch and 8 paths for storage (spa0-3 & spb0-3), can I say that zone1-zone4 is just the same with zone5?
