Fabric Optimization with VSANs

Generally, separate physical fabrics have a high level of switch management and have a higher
implementation cost. Further, the ports in each island may be over-provisioned depending on the fabric
configuration.
By using the Cisco MDS-specific VSAN technology, you can introduce greater efficiency between these
physical fabrics by lowering the cost of over-provisioning and reducing the number of switches to be
managed. VSANs also help you to move unused ports nondisruptively and provide a common redundant
physical infrastructure (see
