In a multi-system configuration:
- All systems must be running the same version of SMWeb Services (12.01 or later) .
- All server management switches in individual systems are joined together in a single server management domain.
- The multi-system configuration has a single server management Site ID.
A 2850 system is a multi-system configuration if one or more of the following are true:
- There are 2850 cliques in different systems.
- There are multiple 2850 systems.
- There are one or more 2800 systems, or one or more 680 systems, in the first cabinet.The first cabinet can contain one or more 2800 systems or one or more 680 systems, in addition to multiple 2850 systems.
- The 2850 system is in a UDA environment.
Nodes in all multi-system configurations share the BYNET V5 InfiniBand switches.
A system consists of a set of Teradata Database nodes and disk arrays. A system contains one or more nodes and disk arrays. A system may contain one or more cliques.
Each system in a multi-system configuration is assigned a unique system name. For example:
- One unique system name is assigned to each Teradata Database system (a set of associated nodes and disk arrays) in a 2850 production system.
- If the first cabinet contains one or more additional 2800 or 2850 systems (associated nodes and disk arrays), a system name is assigned to each Teradata Database system.
- If the first cabinet contains a 680 SMP system, another system name is assigned to the Teradata Database node and disk array in that 680 system.
- If the first cabinet contains a second 680 system, another system name is assigned to the Teradata Database node and disk array in the second 680 system.
- If the first cabinet contains a second system, another system name is assigned to each Teradata Database nodes and disk arrays in the second system.
- Another system name is assigned to the nodes in an Aster cluster.
- Another system name is assigned to the nodes in a Hadoop cluster.
Shared system components (collectives and cabinets, VMSs, BYNET V5 InfiniBand switches, server management switches, and TMSs) are not assigned system names.
Contact Teradata Customer Support to verify which Teradata, Aster, Hadoop, and SAS HPA systems are valid in multi-system configurations, such as a Unified Data Architecture (UDA) environment.
