FIO测试步骤

顺序写：

fio –name=write –filename=”/dev/nvme01np1″ –ioengine=libaio –direct=1 –size=100% –rw=write –bs=128K –numjobs=4 –iodepth=128 –runtime=60 –time_based –thread –group_reporting –output-format=json | jq .jobs[0].write.bw_max

顺序读

fio –name=read –filename=”/dev/nvme01np1″ –ioengine=libaio –direct=1 –size=100% –rw=read –bs=128K –numjobs=4 –iodepth=128 –runtime=60 –time_based –ramp_time=300 –thread –group_reporting –output-format=json | jq .jobs[0].read.bw_max

随机写：

fio –name=randwrite –filename=”/dev/nvme01np1″ –ioengine=libaio –direct=1 –size=100% –rw=randwrite –bs=4K –numjobs=16 –iodepth=128 –runtime=60 –time_based –thread –group_reporting –output-format=json | jq .jobs[0].write.iops_max

随机读：

fio –name=randread –filename=”/dev/nvme01np1″ –ioengine=libaio –direct=1 –size=100% –rw=randread –bs=4K –numjobs=16 –iodepth=128 –runtime=60 –time_based –thread –group_reporting –output-format=json | jq .jobs[0].read.iops_max

然后输入apt install nvme-cli下载组件在输入nvme id-ctrl /dev/nvme1n1 | grep -E ‘mn|fr|sn’查看信息
