Virtual SANs
VSANs (virtual SANs) enable higher security and greater scalability in Fibre Channel fabrics. VSANs
provide isolation among devices that are physically connected to the same fabric. VSANs allow multiple
logical SANs over a common physical infrastructure. VSANs offer the following:

Dynamic VSANs

Port VSAN membership on the switch is assigned on a port-by-port basis. By default each port belongs
to the default VSAN.
You can dynamically assign VSAN membership to ports by assigning VSANs based on the device
WWN. This method is referred to as the Dynamic Port VSAN Membership (DPVM) feature. DPVM
offers flexibility and eliminates the need to reconfigure the VSAN to maintain fabric topology when a
host or storage device connection is moved between two Cisco MDS switches. It retains the configured
VSAN regardless of where a device is connected or moved.

Traffic isolation—Traffic is contained within VSAN boundaries and devices reside only in one
VSAN thus ensuring absolute separation between user groups, if desired.
Scalability—VSANs are overlaid on top of a single physical SAN. The ability to create several
logical VSAN layers increases the scalability of the SAN.
Per VSAN fabric services—Replication of fabric services on a per VSAN basis provides increased
scalability and availability.
Redundancy—Several VSANs created on the same physical SAN ensure redundancy. If one VSAN
fails, there is a configured backup path between the host and the switch.
Ease of configuration—Devices can be added, moved, or changed between VSANs without
changing the physical structure of a SAN. Moving a device from one VSAN to another only requires
configuration at the port level, not at a physical level.
