Limitations of TI zones over FC routers Consider the following when configuring TI zones over FC routers: • A TI zone defined within the backbone fabric does not guarantee that edge fabric traffic will arrive at a particular EX_Port. You must set up a TI zone in the edge fabric to guarantee this. • TI zones within the backbone fabric cannot contain more than one destination router port (DRP) for each fabric. • Only one egress VE_Port for each FC router can be defined within TI zones. • TI over FCR is supported only from edge fabric to edge fabric. Traffic Isolation from backbone to edge is not supported. • Non-TI data traffic is not restricted from going through the TI path in the backbone fabric. • For TI over FCR, failover must be enabled in the TI zones in the edge fabrics. The failover mode for TI zones in the backbone fabric can be enabled or disabled. • TI over FCR is not supported with FC Fast Write. General rules for TI zones Note the following general rules for TI zones: • A TI zone must include E_Ports and N_Ports that form a complete, end-to-end route from initiator to target. • A given port (N_Port or E_Port) used in a TI zone should not be a member of more than one TI zone.If multiple E_Ports are configured that are on the lowest cost route to a domain, the various source ports for that zone are load-balanced across the specified E_Ports. • Each TI zone is interpreted by each switch and each switch considers only the routing required for its local ports. No consideration is given to the overall topology and to whether the TI zones accurately provide dedicated paths through the whole fabric. For example, in Figure 33, the TI zone was configured incorrectly and E_Port "3,9" was erroneously omitted from the zone. The domain 3 switch assumes that traffic coming from E_Port 9 is not part of the TI zone and so that traffic is routed to E_Port 11 instead of E_Port 12, if failover is enabled. If failover is disabled, the route is broken and traffic stops. Domain 1 8 1 9 2 Domain 3 9 10 12 11 87 6 = Dedicated path = Ports in the TI zone Figure 33 TI zone misconfiguration 5 Domain 4 Supported configurations for Traffic Isolation Note the following configuration rules for TI zones: • Traffic Isolation is supported only on the HP StorageWorks 4/8 SAN Switch, 4/16 SAN Switch, SAN Switch 4/32, 4/64 SAN Switch, SAN Switch 4/32B, 8/8 SAN Switch, 8/24 SAN Swtich, 8/40 SAN Switch, 8/80 SAN Switch, 400 Multi-protocol Router, 4/256 SAN Director, and DC SAN Backbone Director (short name, DC Director), all configured in Brocade Native Mode (interopmode 0). Ports in a TI zone must belong to switches that run Fabric OS 6.0 or later. Fabric OS 6.1.x administrator guide 297
