Chapter 6. Networking ports
OpenShift Data Foundation requires specific network ports to be accessible depending on the deployment mode. This section describes the network port requirements for both external and internal mode deployments.
6.1. Network ports for external mode
When deploying OpenShift Data Foundation in external mode, specific network ports must be open between OpenShift Container Platform and the external Ceph storage cluster to ensure proper communication and functionality.
6.1.1. Network ports required between OpenShift Container Platform and Ceph
The following TCP ports must be accessible from OpenShift Container Platform nodes to the external Red Hat Ceph Storage cluster:
| TCP ports | Purpose |
|---|---|
| 6789, 3300 | Ceph Monitor |
| 6800 - 7300 | Ceph OSD, MGR, MDS |
| 9070 | Ceph communication between OpenShift Container Platform nodes and Ceph storage cluster |
| 9283 | Ceph MGR Prometheus Exporter |
For more information about why these ports are required, see Chapter 2. Ceph network configuration of the Red Hat Ceph Storage Configuration Guide.
For detailed information about deploying OpenShift Data Foundation in external mode, see Overview of deploying in external mode.
6.2. Network ports for internal mode
When deploying OpenShift Data Foundation in internal mode, specific network ports are used for communication between OpenShift Container Platform nodes and the internal Ceph storage cluster components.
6.2.1. Network ports required for internal mode deployment
The following TCP ports must be open for internal mode deployments:
| TCP port | Purpose |
|---|---|
| 9070 | CSI-addons sidecar communication between nodes |
| 9080 | Additional Ceph services communication |
For more information about Ceph network configuration, see Chapter 2. Ceph network configuration of the Red Hat Ceph Storage Configuration Guide.
