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 2750 system with 21 cabinets in a 4 node configuration with two cliques per cabinet (8 nodes per expansion cabinet). The topology may differ depending on the number of cabinets in the system. The number of cabinets is determined by the clique configuration (4-node, 2-node, or a combination of 4-node and 2-node) and number of cliques per cabinet.
- Each cabinet shown above represents a collective. 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.
- 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 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).
