Product Management 2 • Fabric services - This function supports the fabric controller (login server) and name server. For redundant directors, fabric services also implement a replication manager that synchronizes node port (N_Port) registration databases between redundant CTP cards and allows CTP failover. • Loop services - This function supports FL_Port initialization for Sphereon 4000-Series Switches and implements arbitrated loop functions, such as transmission of loop initialization primitives (LIPs). • Port hardware services (fabric switches only) - This function supports the application-specific integrated circuit (ASIC) embedded on the CTP card, provides frame handling for fabric switch ports, and provides the application programming interface for light-emitting diodes (LEDs), cooling fans, and power supplies. Refer to Appendix B, Firmware Summary for detailed information about the differences and similarities between the operating systems. The appendix includes three tables that summarize system-related, Fibre Channel protocol-related, and management-related differences. Backup and Restore Features The management server provides two backup and restore features. One feature backs up (to the management server or any LANconnected trivial file transfer protocol (TFTP) server) or restores the configuration file stored in nonvolatile random-access memory (NV-RAM) on a director CTP card, fabric switch, or SAN router. The other feature backs up (to the CD-RW drive) or restores the entire SAN management data directory. The backup and restore features operate as follows: • NV-RAM configuration (director or fabric switch) - The NV-RAM configuration for any managed director or fabric switch is backed up or restored through the associated Element Manager application. Configuration data (stored in NV-RAM on each director or switch) backed up to the management server includes: - Identification data, such as the product name, description, and location. - Port configuration data, such as port names, port states, extended distance settings, and link incident (LIN) alerts.
