Multi cluster IBM Fusion HCI System using Hosted Control Plane

This section answers questions that are related to the Hosted Control Plane in the IBM Fusion HCI System.

  1. Can I install Red Hat® Advanced Cluster Management for Kubernetes (ACM) on a Hosted Control Plane cluster?
    No, ACM is a prerequisite to create a hosted cluster. IBM Fusion HCI System hub and all the Hosted Control Plane prerequisites must be installed on the IBM Fusion HCI System cluster.

  2. How many clusters can I create?
    With the base rack, 5 Hosted Control Plane clusters are supported. Extended racks are 3 additional clusters per node.

  3. Is Global Data Platform supported as a storage for Hosted Control Plane clusters?
    No, this is still a Technical Preview.

  4. What are the network requirements?
    All Hosted Control Plane clusters must have a private or external IP assigned to them to communicate with the control pods on the hub cluster. A load balancer, such as Metallb, must be installed for this purpose.

  5. Can hosted clusters use the Fusion Data Foundation storage?
    Yes, by installing the Fusion Data Foundation client on each hosted cluster, the cluster receives the Data Foundation storage from the Fusion Data Foundation provider on IBM Fusion HCI System.
