(dashed) and VSAN 7 (solid). VSAN 2 includes hosts H1 and H2, application servers AS2 and AS3, and
storage arrays SA1 and SA4. VSAN 7 connects H3, AS1, SA2, and SA3.
The application servers or storage arrays can be connected to the switch using Fibre Channel or virtual
Fibre Channel interfaces. A VSAN can include a mixture of Fibre Channel and virtual Fibre Channel
interfaces.
