Sure. For full disclosure, I also run separate compute and storage. I do think separating storage from a compute cluster can be a good option, but not necessarily for the use case described in the original question.

I’d recommend against separating storage and compute in most small environments. Separating them means you suddenly have higher latency and less bandwidth between your data and whatever you want to do with it. Sure, there are good reasons to do it (centralizing storage for multiple nodes, for example), but go into with your eyes open to the trade-offs.
