Server Management Network for System with Maximum 108 Nodes, 2 InfiniBand Switch Cabinets

  • This configuration is built on the cabinet and collective topology defined in Collectives.
  • The topology shown in the illustration above is based on an appliance system with 1-6 cabinets.
  • This is an alternate topology to the one shown in Inter-Cabinet Server Management Network Topology to 108 Nodes (36-Port Switches).
  • One or more of the processing/storage cabinets shown above may be in a single collective, depending on system configuration. The collective may include Platform Framework Cabinets (not shown).
  • The InfiniBand switch cabinet contains one primary server management Ethernet switch and one secondary server management Ethernet switch.
    Although a cabinet number is not shown for the InfiniBand cabinet, the cabinet number must be unique in the system.
  • Separate primary and secondary paths ensure network redundancy.
  • The primary and secondary networks are configured as follows:
    • The primary Ethernet switch in the InfiniBand switch cabinet acts as the gathering switch for the primary switches in all the cabinets in the system.
    • The secondary Ethernet switch in the InfiniBand switch cabinet acts as the gathering switch for the secondary switches in all the cabinets in the system.
  • For port-to-port cabling, see the appropriate Hardware Installation Guide.
