6750H/HX Server Management Network for System with Maximum 162 Nodes, 2 BYNET V5 Cabinets

  • This configuration is built on the cabinet and collective topology defined in Collectives.
  • The topology shown in the illustration above is based on a 6750H/HX system with 54 cabinets in a 2+1 configuration with one clique per cabinet. The topology may differ depending on the number of cabinets in the system. The number of cabinets is determined by the clique configuration (1+1, 2+1, or 3+1) of the cabinets in the system.
  • One or more of the processing/storage cabinets shown above may be in single collective, depending on system configuration. The collective may include Platform Framework Cabinets (not shown).
  • This configuration has a pair of BYNET V5 cabinets for redundancy (Network-0 Cabinet and Network-1 Cabinet). Each BYNET V5 cabinet contains one primary server management Ethernet switch and one secondary server management Ethernet switch.
    Although cabinet numbers are not shown for the redundant BYNET V5 cabinets (Network-0 Cabinet and Network-1 Cabinet), the cabinet numbers for these cabinets must also be unique in the system.
  • Separate paths for the primary and secondary server management networks of a 6750H/HX system ensure network backup. The primary and secondary networks are configured as follows:
    • The primary Ethernet switch in the BYNET V5 Network-0 Cabinet acts as the gathering switch for the primary switches in all odd-numbered cabinets in the system. The primary switches in those odd-numbered cabinets act as gathering switches for the primary switches in the even-numbered cabinets.
    • The secondary Ethernet switch in BYNET V5 Network-1 Cabinet acts as the gathering switch for the secondary switches in all even-numbered cabinets in the system. The secondary switches in those even-numbered cabinets act as gathering switches for the secondary switches in the odd-numbered cabinets.
    • Each BYNET V5 cabinet connects to the gathering switch in the other BYNET V5 cabinet (Network-0 Cabinet primary to Network-1 Cabinet primary, Network-1 Cabinet secondary to Network-0 Cabinet secondary).
  • For port-to-port cabling, see the appropriate Hardware Installation Guide.
