Apologize for the delay in responding to your question.
The reason we have not supported multiple PM disks is that the performance of accessing a PM disk on the remote CPU socket is a bit worse than accessing the local one. We have not figured out a good way to implement it.

BTW, can you please share something more about your scenario? There might be some alternative solutions.
