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).
