Teradata system performance and capacity scale linearly when additional compute, I/O, and capacity resources are added to the system.
Teradata system is sized and expanded using Teradata cliques. See Clique and System Architecture for Analytics Database Configuration.
You can achieve the system-level design targets by including enough cliques to cover the most demanding and constraining resource element of the target system.
The following table summarizes the key compute, I/O, and capacity attributes of a Teradata clique:
| Clique Configuration | Profile | Cores / Clique (for Analytics Database) | Memory / Clique (for Analytics Database) | 50% RR / RW, 256KB I/O per Clique | Compressed CDS per Clique |
|---|---|---|---|---|---|
| 4+1, 3 arrays | Balanced | 176 | 2,800 GiB | ~12 GB/s | 85 TB |
| 8+1, 6 arrays | Balanced | 352 | 2,800 GiB | ~12 GB/s | 170 TB |
