인텔 NIC 의 SR-IOV 활성화
Dell PowerEdge 의 PCIe 슬롯에 별도 장착한 NIC의 SR-IOV 활성화
Dell 바이오스에서 SR-IOV를 설정하면, 개별 장비는 별도 작업 없이 SR-IOV 가 설정됨
장치 확인
ifconfig -a | grep -i UP lspci -v | grep -i intel | grep -i eth lspci -v | grep -i intel -A 30 | grep -i eth -A 30 cat /sys/class/net/enp65s0f0/device/sriov_totalvfs
LINE 26 에서 SR-IOV 기능이 활성화 된 것을 확인할 수 있다.
LINE 28~29 에서 인텔 NIC의 커널 드라이버 모듈이 bnxt_en 임을 확인할 수 있다.
LINE 30-31 에서 VF (Virtual Function) 개수를 확인할 수 있다.
