NVME와 삼성 850 PRO 256G x 4 - RAID 10 구성이랑 NVME 2개가 한 서버에 세팅되있고, 둘다 ext4 상황에서

데이타 전송을 건 상황이고 한계 속도에 도달하고 속도 변화가 없습니다,

윈도우로 테스트 할때 속도 speedtest.net 속도 테스트 했을때는 8Gbps 정도는 나왔었는데...T.T

답답하네요.

SNMP 64비트 카운트로 카운트 중이구요.

백본 100G에서 10G 4개로 ICX-7750-48F 10/40G 포트에 4개 연결구성

Brocade icx-7750-48F (48포트 10Gbps)에서 서버로 Intel 10G SFP+ DAC 3M 연결중 입니다.

CPU E5-2609V3 x2

RAM 32G
Super Micro 1028U-TNRTP+
CentOS 6.6 X86_64

내장 장치를 이용하다 보니 NVME / 10G SFP+ 2개 모두 CPU 1번에 걸려있는 상태입니다.

지난주에 최대 속도가 1.2Gbps 더 이상 않올라 가더니... 오늘은 1.44G에서 더 이상 않올라 가네요.

네트워크 드라이버는 최신 드라이버로 설치 했는데, 설마 CPU 랑 PCIE 대역 때문이려나요.

사랑과 관심을 부탁드립니다.
