Configurations are single-system or multi-system. In this context, system refers to one of the following definitions:
- Each system has a unique name.
- A Vantage system includes all processing nodes and disk arrays associated with a single instance of Vantage.
- Each 680, 2800, or 2850 is always a separate system.
Shared system components (collectives and cabinets, VMSs, BYNET InfiniBand switches, Server Management switches, and TMSs) are not assigned system names.
Nodes in all multi-system configurations share InfiniBand switches.
In a multi-system configuration, all systems must run the same version of SMWeb Services.
Contact Teradata Customer Support to verify which Teradata and SAS HPA systems are valid in multi-system configurations, such as a Unified Data Architecture (UDA) environment.
