Drives in a 6800H system are a combination of SSDs and HDDs.
The following coexistence configurations are supported for a 6800H 3+1 clique with SDDs and HDDs:
| 6800H 3+1 SSD:HDD Ratio | Configuration |
|---|---|
| 16:72 |
|
| 10.67:96 |
|
| 10.67:112 |
|
| 16:84 |
|
| 10.67:96 |
|
|
These 6800H 3+1 configurations have the same number of AMPs and drives as 2+1 clique configurations, but the AMPs and drives are distributed on three nodes (with 10.67 SSDs per active node; 32 SSDs per 3 active nodes).

Guidelines differ depending on whether the configuration is a variable configuration.
For a 6800H 3+1 clique with four disk arrays, coexisting with a 6750H system, the following guidelines apply:
- Three Teradata Database nodes plus one hot standby node to four disk arrays (3:4 ratio)
- Up to 42 AMPs per node
- Up to 122.67 drives per node (mixed drive types in each disk array)
- Up to 92 drives per array
