Server Management Network for System with Maximum 162 Nodes, 2 InfiniBand Switch Cabinets

  • This configuration is built on the cabinet and collective topology defined in Collective Terminology and Topology.
  • The topology shown in the illustration above is based on an appliance system with 1-9 cabinets.
  • Each cabinet shown above represents a collective. The collective may include Platform Framework Cabinets (not shown).
  • This configuration has a pair of InfiniBand switch cabinets for redundancy (Network-0 Cabinet and Network-1 Cabinet). Each InfiniBand switch cabinet contains one primary server management Ethernet switch and one secondary server management Ethernet switch.
  • Separate paths for the primary and secondary server management networks ensure network backup. The primary and secondary networks are configured as follows:
    • The primary Ethernet switch in the Network-0 Cabinet acts as the gathering switch for the primary switches in all the cabinets in the system.
    • The secondary Ethernet switch in the Network-1 Cabinet acts as the gathering switch for the secondary switches in all the cabinets in the system.
    • Each InfiniBand switch cabinet connects to the gathering switch in the other InfiniBand switch 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.
