Inter-Cabinet Server Management Network Topology to 648 Nodes - Integrated Big Data Platforms

• This configuration is built on the cabinet and collective topology defined in Collectives.
• The topology shown in the illustration above is based on a 1800 system with 216 cabinets in a 2+1 or 3+0 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+0, 1+1, 2+0, 2+1, or 3+0) of the cabinets in the system.
• Except for the Platform Framework Cabinet (PFC) shown above, each cabinet shown represents a collective. A collective may include additional PFCs (not shown).
• A PFC with three pairs of primary/secondary server management switches provides server management connectivity . The primary switches in the cabinet are connected to each other, and the secondary switches are connected to each other.
• Separate paths for the primary and secondary server management networks ensure network redundancy.
• The primary network is configured as follows:
  • The lower primary Ethernet switch in the PFC acts as the gathering switch for the primary switches in odd-numbered cabinets 1-89. The primary switches in those odd-numbered cabinets act as gathering switches for the primary switches in even-numbered cabinets 2-90.
  • The middle primary Ethernet switch in the PFC acts as the gathering switch for the primary switches in odd-numbered cabinets 91-181. The primary switches in those odd-numbered cabinets act as gathering switches for the primary switches in even-numbered cabinets 92-182.
  • The upper primary Ethernet switch in the PFC acts as the gathering switch for the primary switches in odd-numbered cabinets 183-215. The primary switches in those odd-numbered cabinets act as gathering switches for the primary switches in even-numbered cabinets 184-216.
• The secondary network is configured as follows:
  • The lower secondary Ethernet switch in the PFC acts as the gathering switch for the secondary switches in even-numbered cabinets 2-90. The secondary switches in those even-numbered cabinets act as gathering switches for the secondary switches in odd-numbered cabinets 1-89.
  • The middle secondary Ethernet switch in the PFC acts as the gathering switch for the secondary switches in even-numbered cabinets 92-182. The secondary switches in those even-numbered cabinets act as gathering switches for the secondary switches in odd-numbered cabinets 91-181.
  • The upper secondary Ethernet switch in the PFC acts as the gathering switch for the secondary switches in even-numbered cabinets 184-216. The secondary switches in those even-numbered cabinets act as gathering switches for the secondary switches in odd-numbered cabinets 183-215.
• 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.
