ZStack lets one primary storage add multiple clusters, while one cluster can attach multiple primary storages. Currently, the supported scenarios are as follows:
- A cluster can have one or more LocalStorage primary storages attached.
- A cluster can have one or more NFS primary storages attached.
- A cluster can have one or more Shared Block primary storages attached.
- A cluster can have one Shared Mount Point primary storages attached.
- A cluster can have only one Ceph primary storage attached.
