| Component | Rules |
|---|---|
| Generation |
Nodes in coexistence systems must follow coexistence rules for their generation. Each generation must have certified storage for the platform to which it is attached. |
| Arrays |
All 6700C storage drives must be HDD storage drives. All 6700H and 6700X storage drives must be hybrid HDD and SSD storage drives. Contact GSS for clique configurations for coexistence systems.
Drives of different capacities can be mixed within a tray. When mixing drives in an array, RAID pairs/sets should be the same capacity drives. If you mix two different capacities in a RAID pair, PUT treats the larger drive like the smaller drive and you lose the extra capacity.
You cannot mix more than two drive capacities in an array. |
| RAID | You cannot mix RAID types. |
| Design |
Mixed storage design must be matched to data temperature demographics. |
| Teradata |
All 6843 array models can be mixed in the clique. All 6844 array models can be mixed in the clique. |
