Multi-cluster IBM Storage Fusion HCI System using Hosted Control Plane

Create Hosted Control Plane with OpenShift® Virtualization clusters on IBM Storage Fusion HCI System.

A single IBM Storage Fusion HCI System rack can now host multiple OpenShift clusters. Hosted Control Plane enables the nodes in the rack to host multiple clusters virtualized using OpenShift Virtualization. You can create clusters that match your specific workload needs, and clusters can be created on demand.

With Hosted Control Plane for OpenShift Container Platform, you create control planes as pods on a hosting cluster without the need for dedicated virtual or physical machines for each control plane.

For Hosted Control Plane, clusters can be created using IBM Storage Fusion HCI System hub with storage as Fusion Data Foundation. The Fusion Data Foundation service needs to be deployed on the host (base) cluster in order to deploy hosted control plane clusters.

The IBM Storage Fusion HCI System is referred to as the hub cluster and the IBM Storage Fusion spoke is referred to as the hosted cluster.

Important:
  • The supported Fusion Data Foundation versions are 4.16 or higher.
  • The multi-cluster with Hosted Control Plane feature is supported from IBM Storage Fusion HCI System 2.8.1 release.
  • In this release, IBM Storage Fusion HCI System only supports virtual machine based multi-cluster using KubeVirt.
  • Support is available only for the online installation of a stand-alone IBM Storage Fusion HCI System rack.
  • The backup and restore of Hosted Control Plane clusters is not supported in IBM Storage Fusion HCI System. If you want to do backup and restore of the cluster, see Red Hat documentation. .
  • The Hosted Control Plane is supported on IBM Cloud Pak for Integration and IBM Cloud Pak for Data.
