Subscription requirements

IBM Fusion Data Foundation components can run on either OpenShift Container Platform worker or infrastructure nodes, for which you can use either Red Hat CoreOS (RHCOS) or Red Hat Enterprise Linux (RHEL) 8.4 as the host operating system. RHEL 7 is now deprecated. Fusion Data Foundation subscriptions are required for every OpenShift Container Platform subscribed core with a ratio of 1:1.

When using infrastructure nodes, the rule to subscribe all OpenShift worker node cores for Fusion Data Foundation applies even though they do not need any OpenShift Container Platform or any Fusion Data Foundation subscriptions. You can use labels to state whether a node is a worker or an infrastructure node.
