Fabric Optimization with VSANs

Generally, separate physical fabrics have a high level of switch management and have a higher implementation
cost. The ports in each island also may be over-provisioned depending on the fabric configuration.
By using the Cisco MDS-specific VSAN technology, you can have 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
Figure 55: VSAN-Specific Fabric Optimization
VSANs enable global SAN consolidation by allowing you to convert existing SAN islands into virtual SAN
islands on a single physical network. It provides hardware-enforced security and separation between applications
or departments to allow coexistence on a single network. It also allows virtual rewiring to consolidate your
storage infrastructure. You can move assets between departments or applications without the expense and
disruption of physical relocation of equipment.
