For UDA systems (systems connected via InfiniBand or BYNET V5), the InfiniBand switches in the SAS HPA 750 system connect to the InfiniBand or BYNET V5 fabric used by the data source. If the SAS HPA 750 system consists of one or two cabinets, these are the switches in cabinet 1. If the SAS HPA 750 system consists of three or more cabinets, these are the second-tier switches in cabinet 2. Teradata Connect nodes are not required.
Example SAS Cluster to Teradata Network Topology (UDA)
For systems that use Teradata Connect nodes (BYNET V4 and BYNET-over-Ethernet configurations), the SAS HPA 750 system connects to Teradata systems through the Teradata Connect nodes in the SAS HPA appliance cabinet.
