AI Tools

The included FIO tests are detailed below.

4K Random (50/50) Read and Write Performance Test

This tests IOPS and latency performance of 4K random 50/50 read and write tests, under different pressures.

Test Parameters:

bs: 4K
rw: randrw
numjobs: the number of cores of the client server CPU.
iodepth: can be obtained by adjusting different iodepth tests of the latency performance test, under different pressures.

4K Random (70/30) Read and Write Performance Test

This tests IOPS and latency performance of 4K random 70/30 read (70%) and write (30%) tests, under different pressures.

Test Parameters:

bs: 4K
rw: randrw
numjobs: the number of cores of the client server CPU.
iodepth: can be obtained by adjusting different iodepth tests of the latency performance test, under different pressures.

4K Random Read Performance Test

This tests IOPS and latency performance of 4K random read, under different pressures.

Test Parameters:

bs: 4K
rw: randread
numjobs: the number of cores of the client server CPU.
iodepth: can be obtained by adjusting different iodepth tests of the latency performance test, under different pressures.

[global] ramp_time=0 rw=randread refill_buffers loops=1 buffer_compress_percentage=50 buffer_compress_chunk=4096 direct=1 norandommap=1 time_based cpus_allowed_policy=split log_avg_msec=1000 numjobs=12 cpus_allowed=0-11 iodepth=32 randrepeat=0 ioengine=libaio group_reporting=1 runtime=300 bs=4k [job_1] filename=/dev/nvme0n1

4K Random Write Performance Test

This tests IOPS and latency performance of 4K random write, under different pressures.

Test Parameters:

bs: 4K
rw: randwrite
numjobs: the number of cores of the client server CPU.
iodepth: can be obtained by adjusting different iodepth tests of the latency performance test, under different pressures.

[global] ramp_time=0 rw=randwrite refill_buffers loops=1 buffer_compress_percentage=50 buffer_compress_chunk=4096 direct=1 norandommap=1 time_based cpus_allowed_policy=split log_avg_msec=1000 numjobs=12 cpus_allowed=0-11 iodepth=32 randrepeat=0 ioengine=libaio group_reporting=1 runtime=300 bs=4k [job_1] filename=/dev/nvme0n1

128K Bandwidth Performance Test

This tests the highest bandwidth that can be obtained in different IO scenarios.

Test Parameters:

bs: 4K
rw: randrw
numjobs: The number of cores of the client server CPU.
iodepth: The highest IOPS that can be obtained by adjusting different iodepth tests. This is generally 1 or 2; i.e., testable.

[global] ramp_time=0 rw=randwrite # WRITE #rwmixread=100 # When using randrw in the line above refill_buffers loops=1 buffer_compress_percentage=50 buffer_compress_chunk=4096 direct=1 norandommap=1 time_based cpus_allowed_policy=split log_avg_msec=1000 numjobs=12 cpus_allowed=0-11 iodepth=2 randrepeat=0 ioengine=libaio group_reporting=1 runtime=300 bs=128k [job_1] filename=/dev/nvme01
