Why each option
VMware vSphere 6.x supports two Fibre Channel zoning configurations: Single-Initiator and Single-Initiator-Single-Target, with the latter being the recommended best practice.
Single-Initiator zoning places one HBA initiator per zone and is a supported configuration in vSphere 6.x, allowing that initiator to access multiple targets within the zone.
Single-Initiator-Single-Target zoning is the VMware-recommended best practice for Fibre Channel in vSphere, placing exactly one initiator and one target per zone for maximum isolation and predictable behavior.
Multiple-Initiators-Single-Target zoning is not a VMware-supported or recommended configuration for vSphere 6.x FC SANs because it can cause unpredictable behavior and complicates troubleshooting.
Multiple-Initiators-Multiple-Targets zoning is explicitly discouraged by VMware for vSphere environments because it reduces isolation, increases the blast radius of failures, and is not a supported configuration.
