Firmware Summary Table B-5 E/OS versus E/OSn and E/OSi - Fibre Channel Protocol-Related Differences (Continued) Feature E/OS 7.0 E/OSn 6.0 E/OSi 4.6 Expansion port (E_Port) E_Port staging not supported. staging The Intrepid 10000 Director supports E_Port staging. The director allows only one E_Port connection to a neighbor switch to take part in a fabric build process. Upon process completion, subsequent E_Ports to neighbor switches are brought up (staged). In addition, staged E_Ports are brought up in groups to minimize Class F traffic and avoid overloading. E_Port staging not supported. ESS payload processing and domain port number zoning E/OS Version 6.0 (or earlier) handshakes the ESS sequence but does not apply content of ESS payload to calculate port numbering (PN) to logical port address (PA) mapping. Legacy directors and switches are assumed to use an offset of four for PN to PA mapping. The Intrepid 10000 Director sends and accepts payloads specifying minimum and maximum logical port addresses and processes payload content to calculate PN to PA mapping. A correct mapping scheme interprets domain port number zoning enforcement across the fabric and allows the director to participate in a legacy fabric with domain port number zoning. E/OSi handshakes the ESS sequence. However, domain port number zoning not supported. Registered state change notification (RSCN) coalescing Only fabric login (FLOGI) and Name Server events are coalesced. The Intrepid 10000 Director coalesces all events that trigger and transmit RSCNs to N_Ports. This minimizes the number of RSCNs generated. SAN routers coalesce all RSCN events. Generating fabric format RSCNs after CTP failover (directors) Does not replicate RSCN event triggers, therefore transmits a fabric format RSCN to all attached devices after CTP card failover. Replicates events that trigger RSCNs to the backup CTP, therefore does not generate a fabric format RSCN after CTP failover. RSCNs after CTP failover not supported. Hop count restriction Exchange switch capabilities (ESC) support Hop count of up to seven is supported. Devices more than seven hops away cannot be reached. SW_ILS ESC sequence not supported. No hop count restriction is applied. The Intrepid 10000 Director processes SW_ILS ESC sequences to identify neighboring director ports. No hop count restriction is applied. SW_ILS ESC sequence not supported. B-4 McDATA Products in a SAN Environment - Planning Manual
