Cisco Nexus 5000 Series Nx-Os San Switching Configuration Guide, Release 5.2(1)N1(1 - Cisco Nexus 5000 Series Configuration Manual

Information About VSANs
• Every instance of a VSAN runs all required protocols such as FSPF, domain manager, and zoning.
• Fabric-related configurations in one VSAN do not affect the associated traffic in another VSAN.
• Events causing traffic disruptions in one VSAN are contained within that VSAN and are not propagated
to other VSANs.
The following figure shows a fabric with three switches, one on each floor. The geographic location of the
switches and the attached devices is independent of their segmentation into logical VSANs. No communication
between VSANs is possible. Within each VSAN, all members can talk to one another.

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.
