5.6. NVIDIA 네트워크 운영자 구성

NVIDIA 네트워크 운영자는 NVIDIA GPUDirect RDMA 워크로드를 지원하기 위해 NVIDIA 네트워킹 리소스와 드라이버, 장치 플러그인과 같은 네트워킹 관련 구성 요소를 관리합니다.

사전 요구 사항

NVIDIA 네트워크 운영자를 설치했습니다.

프로세스

다음 명령을 실행하여 컨트롤러가 nvidia-network-operator 네임스페이스에서 실행 중인지 확인하여 네트워크 운영자가 설치되고 실행 중인지 확인합니다.

oc get pods -n nvidia-network-operator

$ oc get pods -n nvidia-network-operator
