My new company currently have 45 ESX Servers and its zoned to an Hitachi Storage on the same port across all the servers.
They have 45 Individual zones for each servers. I know its best practive for (1I to 1T)
but this quot is directly out of the VMware guide. (ESX Server hosts that use shared storage for virtual machine failover or load
balancing must be in one zone.)
What do you recommend?
Thanks in advance.

One initiator to One target.
The point is not to One zone for al ESX hosts in case of LB or Failover, but having access to the same shared storage.
How you'll accomplish that on the SAN and on your array is up to you.

Its actually being LB across both Fabric on different Storage Port. So redundancy is there on the Fabric / Storage Port / Controller.
My Question is more along the line of zone cleanup so thing would be neater, instead of 45 individual zones, one zones.

My opinion is still one target one initiator.
In the end your zone will resemble a SCSI bus. I don't know about you, but I certainly don't want 45 initiators on the bus. If one is acting up it will affect all other host. By keeping them separated they won't affect each other and will looks more like the traditional SCSI bus.
