Considerations and Limitations
Consider the following limitations before deciding to fold or unfold.
|Database license tier||Developer tier is not supported.|
|Maximum node limit||Do not unfold the system beyond the maximum node limit.
For BYOL, check to ensure you have enough TCores before you unfold the system.
|Maximum data disk count per node limit||Do not fold the system if it increases the volume count beyond 32 for DS14_v2 and 40 for DS15_v2.|
|Maximum unfold limit||Do not unfold the system beyond the maximum node count limit. You cannot go beyond the minimum storage subpool count of 1 per node.
Do not unfold beyond four times the size of a launched 16 or 20 AMPs per node system.
|Minimum fold limit||Do not fold the system beyond the maximum storage subpool count of 4 per node.|
|Power of two scaling limit||A system can only be unfolded to 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 unfolded, it can only be folded in two times (2x, scale factor x/2), or four times (4x, scale factor x/4).
