Explanation
A VSAN (Virtual Storage Area Network) is the Fibre Channel equivalent of an Ethernet VLAN. It logically partitions a single physical fabric into multiple isolated fabrics, so devices in different VSANs cannot communicate directly even though they share the same switches and cabling. This provides fault isolation (an event in one VSAN does not affect others), security, and traffic separation. ISL (Inter-Switch Link) is a physical link between switches, IVR enables routing between VSANs, and VoQ (Virtual Output Queue) is a switching mechanism - none of these define logical isolation.
