Multiple cliques can be allocated within a single Teradata system to scale compute, I/O, and capacity to achieve system-level design targets. The following table provides examples of such scaling using the 4+1 and 8+1 clique building blocks:
| Cliques | Analytics Database Nodes (Active+HSN) | Cores / System | Memory / System | 50% RR / RW, 256KB I/O per System | CDS per System |
|---|---|---|---|---|---|
| 4+1 Clique Building Blocks | |||||
| 8 | 32+8 (40) | 1408 | ~22 TiB | ~96 GB/s | ~680 TB |
| 8+1 Clique Building Blocks | |||||
| 8 | 64+8(72) | 2816 | ~44 TiB | ~192 GB/s | ~1360 TB |
Teradata can provide linear performance and capacity by scaling systems out in size. The total system size is defined by the lesser of the following methods:
- Host Connectivity
- Up to 13 cliques can be supported. See Networking for Analytics Database Configuration.
- Single-System Availability
- Single-system availability (or uptime) is defined by total system size. Make sure the availability profile of a candidate system is acceptable by using an appropriate business continuity solution. See System Availability and Durability.
