    Recommended cluster operators

    The following operators are required for clusters running distributed virtual unit (vDU) applications and are part of the baseline reference configuration:

    • Node Adjustment Operator (NTO). NTO packages previously provided functionality with the Performance Addon Operator, which is now part of NTO.

    • PTP operator

    • SR-IOV Network Manager

    • Red Hat OpenShift log operator

    • local warehouse operator

    Recommended cluster core configuration

    Always use the latest version of the realtime kernel supported by your cluster. Make sure to apply the following settings to the cluster:

    1. ensure the followingextraKernelArgsis defined in the cluster performance profile:

      1. specification:
      2. extraKernelArgs:
      3. - "rcupdate.rcu_normal_after_boot=0"
      4. - "efi=runtime"
    2. make sure thatperformance patchprofile oncoordinatedCR configures the correct CPU isolation set to matchisolatedCPU is set to relevantPerformanceProfilCR, for example:

      1. specification:

      1The CPUs detected depend on the hardware configuration of the host, specifically the number of CPUs available on the system and the CPU topology.

    Real-time kernel version control

    Always use the latest version of the realtime kernel on OKD clusters. If you are not sure which kernel version is used in the cluster, you can compare the current live kernel version with the release version using the following procedure.

    prerequisites

    Procedure

    1. Run the following command to get the cluster version:

      1. $ OCP_VERSION=$(ocI getcluster version-o jsonpath='{.status.desired.version}{"\n"}')
    2. Get the SHA number for the launch image:

      1. $ DTK_IMAGE=$(oc adm traffic information--image-For=guide-tool box dock.io/open shift-release-developer/ocp-release:$OCP_VERSION-x86_64)
    3. Run the launch image container and extract the kernel version bundled with the current cluster version:

      1. $ podman mail--rm $DTK_IMAGE rpm-qa|grep'kernel-rt-core-' |sed's#kernel-rt-core-##'

      sample output

      1. 4.18.0-305,49.1.rt7.121.el8_4.x86_64

      This is the default realtime kernel version that ships with the release.

      The realtime kernel is specified by the string.rtin the main version.

    Verification

    Verify that the kernel version specified for the current cluster version matches the real-time kernel running on the cluster. Run the following commands to check the current kernel version in real time:

    1. Open an external shell connection to the cluster node:

      1. debug node $oc/<node_name>
    2. Check major version in real time:

      1. SH-4.4# unname -r

      sample output

      1. 4.18.0-305,49.1.rt7.121.el8_4.x86_64

    Make sure recommended cluster configurations are used

    You can verify that the clusters run the correct configuration. The following procedure describes how to verify the various settings required to deploy a DU application on OKD 4.13 clusters.

    prerequisites

    • You've deployed a cluster and configured it for vDU workloads.

    • You have installed the OpenShift CLI (oc).

    • You are logged in as a user withcluster administratorprivileges.
