Consider the following limitations before scaling out or scaling in.
| Considerations | Limitations |
|---|---|
| Database license tier | Developer tier is not supported. |
| Maximum node limit | Do not scale out the system beyond the maximum node limit. For BYOL, make sure you have enough TCores before you scale out the system. |
| Maximum data disk count per node limit | Do not scale in the system if it increases the volume count beyond 32 for DS14_v2 and 40 for DS15_v2. |
| Maximum scale out limit | Do not scale out the system beyond the maximum node count limit. You cannot go beyond the minimum storage subpool count of 1 per node. Do not scale out beyond four times (4x) the size of a launched 16 or 20 AMPs per node system. |
| Minimum scale in limit | Do not scale in the system beyond the maximum storage subpool count of 4 per node. |
| Power of two scaling limit | A system can be scaled out to only two times (2x) the size, which doubles the total node count (half the premium storage), or four times (4x) the size, which quadruples the total node count (quarter the premium storage). Assuming a system was previously scaled out, it can be scaled in only two times (2x, scale factor x/2) or four times (4x, scale factor x/4). |
