About Overlay VSANs

VSANs enable deployment of larger SANs by overlaying multiple logical SANs, each running its own
instance of fabric services, on a single large physical network. This partitioning of fabric services
reduces network instability by containing fabric reconfiguration and error conditions within an
individual VSAN. VSANs also provide the same isolation between individual VSANs as physically
separated SANs. Traffic cannot cross VSAN boundaries and devices may not reside in more than one
VSAN. Because each VSAN runs separate instances of fabric services, each VSAN has its own zone
server and can be zoned in exactly the same way as SANs without VSAN capability.
