Cisco MDS 9000 Family Virtual SAN
Virtual Storage Area Networks (vSANs) are built on a common physical infrastructure. Each vSAN provides its own fabric services, such as zoning, name and server, and is functionally isolated from other vSANs on the same switch. Sharing of common resources across vSANs can be accomplished using Inter-vSAN Routing, which is integrated on any port and incurs no additional resources on the switch. By using vSANs, customers can consolidate separate physical SAN fabrics into one large fabric for ease of management and reduced total cost of ownership (TCO), while providing secure and reliable isolation of different storage islands.
