Networks for a System with Dedicated StorageΒΆ

For a system that uses dedicated storage, StarlingX recommends a full network configuration.

StarlingX systems with dedicated storage include storage hosts to provide Ceph-backed block storage. Network loading is moderate to high, depending on the number of worker hosts, containers, and storage hosts. The following network configuration typically meets the requirements of such a system:

  • A 10GE internal management network for internal system infrastructure management and disk I/O traffic to and from storage nodes.

  • An OAM network.

  • A cluster host network for private container-to-container networking within the cluster and optionally for external connectivity of container workloads.

    If a cluster host network is not used for external connectivity of container workloads, then either the OAM port or other configured ports on both the controller and worker nodes are used for container workloads connectivity to external networks.

  • An optional PXE boot network:

    • if the internal management network is required to be on a VLAN-tagged network

    • if the internal management network is shared with other equipment

On moderately loaded systems, the OAM network can be consolidated on the management or infrastructure interfaces.


You can enable secure HTTPS connectivity on the OAM network.
