Planning host interface connections
Plan network interface connections for OpenShift nodes based on node type and storage network requirements.
OpenShift nodes can be separated into following three types:
- OpenShift control plane nodes
- OpenShift worker nodes
- Fusion Data Foundation storage nodes
Each type requires different connections to the storage cluster as follows:
- All OpenShift nodes require access to the OpenShift machine network
- Control plane nodes do not require any connection to storage networks
- If Fusion Data Foundation PVCs are needed on control plane nodes (not recommended), treat them as worker nodes
- If control plane nodes are used as Fusion Data Foundation storage nodes, treat them as storage nodes
- Worker nodes run Ceph-CSI driver daemons to mount PVC storage to Pods and therefore require a connection to the Fusion Data Foundation public network (if used)
- Storage nodes require access to all used storage networks
