3: The 2-port HBAs in a vSphere hosts should be zoned to a single node-pair (no need to connect to all nodes). The following host is then flipped to the other node-pair to balance the load (There is some inconsistency out there – some say that one shall zone to all four nodes)
I agree with Keith's layout as that's how I do it hear as well. 1 Host -> 4 nodes.
SAN-A Zones:
Host1 port 1, 0:1:1, 1:1:1
Host2 port 1, 2:1:1, 3:1:1
SAN-B Zones:
Host1 port 2, 2:1:2, 3:1:2
Host2 port 2, 0:1:2, 1:1:2
To make zoning easier, I have aliases for my 3PAR front end ports labeled in sets, and I rotate hosts through the sets to keep them balanced.
On SAN-A:
T800-1_4-5-1_SET1
T800-1_5-5-1_SET1
T800-1_6-5-1_SET2
T800-1_7-5-1_SET2
T800-1_4-5-3_SET3
T800-1_5-5-3_SET3
T800-1_6-5-3_SET4
T800-1_7-5-3_SET4
On SAN-B:
T800-1_4-5-2_SET4
T800-1_5-5-2_SET4
T800-1_6-5-2_SET1
T800-1_7-5-2_SET1
T800-1_4-5-4_SET2
