Enhanced trunking support for the FC4-48 port blade in the 4/256 SAN Director is summarized in Table 80. Table 80 Trunking support for 4/256 SAN Director and DC Directors with supported blades (Condor and Condor2 ASIC) Mode Distance Number of 2 Gbps ports Number of 4 or 8 Gbps ports LE 10 km 48 (six 8-port trunks) 48 (six 8-port trunks) L0 Normal See note below. LD 200 km 4 (one 2-port trunk per Condor) LD 250 km 4 (one 2-port trunk per Condor) LD 500 km 0 48 (six 8-port trunks) 0 0 0 LS Static See note below. NOTE: The LO mode supports up to 5 km at 2-Gbps, up to 2 km at 4-Gbps, and up to 1 km at 8-Gbps. The distande for LS mode is static. You can specify any distance greater than 10 km, for example 25 km, 50 km, and 100 km. The DCX-4S Backbone supports long distance modes LO, LE, LS, and LD. F_Port masterless trunking On edge switches, the masterless trunking feature is called F_Port masterless trunking because it trunks F_Ports; on the switches running in Access Gateway mode, this feature is called Access Gateway N_Port trunking because it trunks the N_Ports. F_Port trunking, provides a Trunk group between a switch (N_Port) in Access Gateway (AG) mode and Condor-based platforms. This feature keeps F_Ports from becoming disabled in the case where they are mapped to an N_Port on a switch in Access Gateway mode. With F_Port trunking, any link within a trunk can go off line or become disabled, but the trunk remains fully functional and there are no re-configuration requirements. F_Port trunking prevents reassignments of the Port ID when F_Ports go offline and it increases F_Port bandwidth. This feature supports the HP StorageWorks SAN Switch 4/32, 4/32B, 4/64 SAN Switch, 8/8 SAN Switch, 8/24 SAN Switch, 8/40 SAN Switch, 8/80 SAN Switch, 4/256 SAN Director and the DC Director enterprise-class platforms running Fabric OS 6.1.x. F_Port masterless trunking interoperates between Access Gateway (AG), 2 Gbps, 4 Gbps, and 8 Gbps-based platforms. This feature does not Fabric OS 6.1.x administrator guide 375
