기본 Redhat InfiniBand 지원에 비해 MLNX OFED 설치에 이점이 있습니까?

RHEL 8.8에서는 Mellanox InfiniBand 하드웨어를 사용하는 사용자가 선택할 수 있습니다. Red Hat과 함께 제공되는 그룹 설치 InfiniBand Support(설치 중에 선택)를 활용하여 InfiniBand 네트워킹을 활성화하거나 스크립트를 선택 MLNX_OFED_LINUX-23.04-1.1.3.0-rhel8.8-x86_64.iso하고 실행하여 mlnxofedinstallRed Hat 패키지를 자체 패키지로 대체할 수 있습니다.

펌웨어 업데이트 외에 Red Hat 경로를 통해 MLNX 경로를 사용하여 InfiniBand를 설정하면 어떤 이점이 있는지 아는 사람이 있습니까?

MLNX 접근 방식에는 일반적으로 더 많은 설정과 구성이 필요하므로 Red Hat에서 제공하는 성능상의 이유보다는 MLNX 접근 방식(하드웨어를 사용하고 있다는 점을 감안할 때)을 사용하는 데 관심이 있습니다.
