Drives in a 6800H system are a combination of SSDs and HDDs.
The following coexistence configurations are supported for a 6800H 2+1 clique with SSDs and HDDs:
| 6800H 2+1 SSD:HDD Ratio | Configuration |
|---|---|
| 16:72 |
|
| 16:144 |
|
| 16:168 |
|
| 16:84 |
|
| 16:144 |
|
Guidelines differ depending on whether the configuration is a variable configuration.
For a 6800H 2+1 clique with four disk arrays, coexisting with a 6750H system, the following guidelines apply:
- Two Teradata Database nodes plus one hot standby node to four disk arrays (2:4 ratio)
- Up to 42 AMPs per node
- Up to 184 drives per node (mixed drive types in each disk array)
- Up to 92 drives per array
