InfiniBand Network Topology for a Maximum 1,458 Node System: Switch-to-Switch

InfiniBand Network Topology for a Maximum 1,458-Node System (324-Port Switches): Node-to-Switch

  • Consists of eighty-one processing/storage cabinets and two required InfiniBand switch cabinets (for redundancy).
  • Cabinets contain processing nodes and a VMS for server management.
  • Cabinets can contain other nodes and servers.
  • Scalable up to 1,458 nodes and servers in any combination.
  • 36-port InfiniBand first tier switches provide node-to-switch connections for the redundant InfiniBand networks (Network-0 and Network-1). Connections are shown in the figure.
    The pattern shown for Cabinet 4, Cabinet 5, and Cabinet 6 repeats.
    • Each processing node contains a dual port InfiniBand adapter that connects to the InfiniBand switches.
    • Other nodes and servers may contain a dual port InfiniBand adapter that connects to the InfiniBand switches.
    • Individual optical InfiniBand cables are used to connect nodes in cabinets with switches to nodes in cabinets without switches.
  • 324-port InfiniBand switches provide switch-to-switch connections for the redundant InfiniBand networks (Network-0 and Network-1). Connections are shown in the figure.
    • 324-port InfiniBand second tier switches in the InfiniBand cabinet connect to 36-port first tier switches in processing/storage cabinets.
    • Uplink cables connect InfiniBand switches to InfiniBand switches.
  • If the system is included in a UDA environment, some ports on the second tier InfiniBand switches are used for UDA connections. The number of ports needed depends on the UDA configuration. For more information, see the Teradata Unified Data Architecture InfiniBand and Server Management Configuration Guide, B035-6001.
  • For port-to-port cabling, see the appropriate Hardware Installation Guide.
