Server Management Network for System with Maximum 486 Nodes, 1 InfiniBand Switch Cabinet

  • This configuration is built on the cabinet and collective topology defined in Collectives.
  • This configuration illustrates topology for one to twenty-seven processing/storage cabinets.
  • Each processing/storage cabinet shown above is in a single collective. One collective includes the InfiniBand switch cabinet.
  • The System VMS in the base cabinet (Cabinet 1) hosts the SWS VM, Viewpoint VM, and CMIC VM. Each expansion cabinet contains a Cabinet VMS that hosts the CMIC VM.
    In systems with an Enterprise SWS and an Enterprise Viewpoint Server, the System VMS hosts only a CMIC VM.
  • This configuration has a one InfiniBand cabinet with two InfiniBand switches (Network-0 and Network-1). The InfiniBand 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 paths for the primary and secondary server management networks ensure network redundancy.
  • The primary and secondary networks are configured as follows:
    • The primary Ethernet switch in the InfiniBand cabinet acts as the gathering switch for the primary switches in cabinets 1-27.
    • The secondary Ethernet switch in the InfiniBand cabinet acts as the gathering switch for the secondary switches in cabinets 1-27.
  • If the system is included in a UDA environment, UDA ports will be accommodated by open ports on the primary and secondary server management switches for UDA connections to the other system or systems in the UDA environment. These UDA connections are not shown in the illustration above. 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.
