System Topology for Up To 8 Cabinets - Data Warehouse Appliances

The system can accommodate up to 8 cabinets using a single pair of second-tier 36-port switches. This allows for up to 96 nodes.

Second-tier switches are located in Cabinet 2.

• The system consists of up to 8 cabinets.
• The first cabinet contains 2850 processing nodes (2-node or 4-node cliques) and may contain additional systems (680, 2800, or 2850 systems).
• The other cabinets contain 2850 processing nodes (2-node or 4-node cliques).
• The first cabinet contains a System VMS for server management, and may contain additional TMSs.
• Each additional cabinet may contain a Cabinet VMS for server management.
• Each pair of cabinets (Cabinets 1 and 2, Cabinets 3 and 4, and so on) form a group of up to 24 nodes. The nodes in the cluster share the first-tier switches in the first cabinet of the pair.
• Eight ports on each of the InfiniBand switches in Cabinet 1, Cabinet 3, Cabinet 5, and Cabinet 7 are used to provide the uplink connections to the second-tier switches.
• Eight uplink connections from each first-tier switch connect to the second-tier switch (for each fabric).
• When connected to a UDA network, the second-tier switches can be used for UDA connections. For more information, see the Teradata Unified Data Architecture InfiniBand and Server Management Configuration Guide, B035-6001.
