What are your requirements? Sounds like you want to do your own storage infra? What stateful apps are you running?
- Databases. (Usually PostgreSQL, seems like it's pretty easy to setup to replicate between PostgreSQL instances.)
- Qdrant, or milvus. (seems like they're support replication between instances, we've *accidentally* running a replicated DB on Single Ceph Cluster)
- Some user generated contents. (usually from Jupyter Environment)

We don't actually have a "storage infra". it's just a bunch (I really don't think 2 HDD is a part of "Bunch") of disks attached to each machines (or node).
