Setting up Node Feature Discovery

Node Feature Discovery (NFD) Operator manages the deployment and lifecycle of the NFD add-on to detect hardware features and system configuration, such as PCI cards, kernel, operating system version, etc.

Prerequisites

• Provisioned RHOCP cluster. Follow steps here.

Install NFD Operator

Follow the guide below to install the NFD operator using CLI or web console.

• Install from the CLI

• Install from the web console

Configure NFD Operator

Note: As RHOCP cluster administrator, you might need to merge the NFD operator config from the following Custom Resources (CRs) with other NFD operator configs that are already applied on your cluster.

1. Create NodeFeatureDiscovery CR instance.

$ oc apply -f https://raw.githubusercontent.com/intel/intel-technology-enabling-for-openshift/main/nfd/node-feature-discovery-openshift.yaml 

2. Create NodeFeatureRule CR instance.

$ oc apply -f https://raw.githubusercontent.com/intel/intel-technology-enabling-for-openshift/main/nfd/node-feature-rules-openshift.yaml

Verification

Use the following command to get the node name

$ oc get nodes

Use the command shown below to verify whether the nodes are labeled properly by NFD:

$ oc describe node <node_name> | grep intel.feature.node.kubernetes.io

Example output:

intel.feature.node.kubernetes.io/dgpu-canary=true
intel.feature.node.kubernetes.io/gpu=true

Labels Table

Label	Intel hardware feature
intel.feature.node.kubernetes.io/gpu=true	Intel® Data Center GPU Flex Series or Intel® Data Center GPU Max Series
intel.feature.node.kubernetes.io/sgx=true	Intel® SGX
intel.feature.node.kubernetes.io/qat=true	Intel® QAT
intel.feature.node.kubernetes.io/dsa=true	Intel® DSA
