Cisco MDS 9000 Fabric Manager Switch Configuration Guide
16-2
Accesses resources across VSANs without compromising other VSAN benefits.
Transports data traffic between specific initiators and targets on different VSANs without merging
VSANs into a single logical fabric.
Shares valuable resources (like tape libraries) across VSANs without compromise.
Provides efficient business continuity or disaster recovery solutions when used in conjunction with
FCIP.
Compliant with Fibre Channel standards compliant.
Incorporates with third-party switches--if the IVR-enabled VSANs are configured in interop 1
mode.
Native VSAN—The VSAN to which an end device logs on is called a native VSAN for that end
device.
Inter-VSAN zone (IVZ)—Defines a set of end devices s that are allowed to communicate across
VSANs within their interconnected SAN fabric. This definition is based on their port World Wide
Names (pWWNs) and their native VSAN association. You can configure up to 200 IVZs and 2000
IVZ members on any switch in the Cisco MDS 9000 Family.
Inter-VSAN zone sets (IVZS)—One or more IVZs make up an IVZS. You can configure up to 32
IVZSs on any switch in the Cisco MDS 9000 Family. Only one IVZS can be active at any time.
IVR path—An IVR path is a set of switches and inter-switch links via which a frame from one
end-device in one VSAN can reach another end-device in some other VSAN. Multiple paths can
exist between two such end-devices.
IVR-enabled switch—A switch in which the IVR feature is enabled.
Edge VSAN—An edge VSAN refers to a VSAN which initiates (source edge-VSAN) or terminates
(destination edge-VSAN) an IVR path. Edge VSANs may be adjacent to each other or they may be
connected by one or more transit VSANs. In
An edge VSAN for one IVR path can be a transit VSAN for another IVR path.
Transit VSAN—Transit VSAN is a VSAN that exists along an IVR path from the source edge VSAN
of that path to the destination edge VSAN of that path.
When the source and destination edge VSANs are adjacent to each other, then a transit VSAN is not
required between them.
Border switch—An IVR-enabled switch that is a member of two or more VSANs.
Edge switch—A switch to which a member of an IVR zone has logged in. Edge switches are
oblivious to the IVR configurations in the border switches. Edge switches need not be IVR enabled.
