Fusion HCI - container placement optimisation through the use of taints and tolerations

IBM Storage Fusion HCI is an appliance based configuration which has a set of standard best practices.

some of these practices include not deploying standard container workloads on special nodes (AFM / GPU)

however by default Fusion HCI has no logic or configuration rules to prevent the fusion operator or RHOCP operators deploying containers onto special nodes.

RH OCP provides tools (Taint / Toleration - node affinity / anti-affinity) to cater for these special node use cases, but IBM takes no advantage of these tools provided natively in OCP.

by levegering the tools that are integrated into the OCP platform, and building out the logic necessary to maintain IBM's best practices recommendations IBM can enhance the client experience with Fusion HCI and help customers ensure that they continue to meet IBM's best practice recomenations.

    I believe we now taint AFM nodes to prevent non-afm workloads from being scheduled on them

    Can you please provide a specific example? Lack of specificity makes this hard to action.
