Traffic Isolation Zoning over FC routers
TI zoning can be used with FC routed fabrics with failover enabled. To achieve end-to-end traffic isolation across the metaSAN, TI zones
must be configured at each relevant edge fabric, and the backbone fabric, within the metaSAN.
Some VE_Port-based features, such as tape pipelining, require the request and corresponding response traffic to traverse the same
VE_Port tunnel across the metaSAN. To ensure that the request and response traverse the same VE_Port tunnel, you must set up
Traffic Isolation zones in the edge and backbone fabrics.
∙ Set up a TI zone in an edge fabric to guarantee that traffic from a specific device in that edge fabric is routed through a
particular EX_Port or VEX_Port.
∙ Set up a TI zone in the backbone fabric to guarantee that traffic between two devices in different fabrics is routed through a
particular ISL (VE_Ports or E_Ports) in the backbone.
This combination of TI zones in the backbone and edge fabrics ensures that the traffic between devices in different fabrics traverses the
same VE_Port tunnel in a backbone fabric. Figure 44 shows how three TI zones form a dedicated path between devices in different
edge fabrics. The backbone fabric can contain one or more FC routers.
