so single mode fiber connecting both switches ?  Each HBA should be zoned to at least one port on SPA and SPB, ie:  hba1 - SPA0 hba1 - SPB1  hba2 - SPA1 hba2 - SPB0
Hello, I know there are several conversations regarding this topic, but I have not been able to find a solution that answers my specific question.  We have (2) VNX 5300s in our organization.  Array (A) is serving up LUNs to our VMware environment, and is replicating to another, Array (B), down the street.  We only have (1) fabric for our SAN.  Currently we have one port from each SP plugged into a different switch at each site in the case of a switch failure.    My question is how should the SPs be zoned to each of my VMware HBAs (there are two HBAs per host).  Thanks in advance! Rob
