Best Practice for a FC SAN Zone has always been one Iniator Port and one Target Port per Zone. This insures that communication between the Server and Storage remain "clean" and also makes Troubleshooting easier.
If your lazy and do not feel like making so many Zones, you can also have a Zone with one Iniator Port and multiple Target Ports, if your Storage has multiple Controllers/Ports. Of course, when you have multiple Fabrics, you should not mix the two together.
That being said, I was recently in a MOC Hyper-V + VMM Course and the Instructor said that Microsoft Best Practise for a Hyper-V Cluster is to put one Iniator Port from each Cluster Node (multiple Iniator Ports) with multiple Target Ports all in one Zone. The reason being, he said, was that the Cluster reacted faster in case of a Failover. I have tried to find Microsoft Documentation that Support this statement but have not been able to find any.
Can anyone point me to any Documentation that backs this "Best Practise" Statement up or if you are doing the same thing in your Organisation?
Thanks in advance!
