Instal FIO Tool

FIO is an open source tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user. Its binary packages have been part of the linux distribution repositories. Here are some examples to install FIO.

## For Ubuntu
sudo apt-get -y install fio

## For CentOS
sudo yum -y install fio

Find the TEEIO Device information

Follow below steps to prepare the TEEIO Device information which will be used in FIO command options. Step 1: Use lspci to check the device (For example device's BDF is da:00.0)

# lspci -s da:00.0 -v
da:00.0 Non-Volatile memory controller: SomeVendor's Device [NVM Express])
        Subsystem: SomeVendor's Device aa99
        Physical Slot: 19
        Flags: bus master, fast devsel, latency 0, IRQ 16, NUMA node 0
        ... ...
        Kernel driver in use: nvme
        Kernel modules: nvme

In the output of lspci, check Kernel driver in use: nvme

Step 2: Check the actual device

# ls /sys/bus/pci/devices/0000\:da\:00.0/nvme
nvme5

Step 3: Make sure /dev/nvme5 exists

# ls /dev/nvme5
/dev/nvme5

Prepare the FIO command

Run below command to test I/O traffic with FIO.

FILENAME=/dev/nvme5

sudo fio --filename=${FILENAME} --rw=rw \
    --direct=1 --bs=4K --ioengine=libaio \
    --runtime=300 --numjobs=1 --time_based \
    --group_reporting --name=seq_readwrite \
    --iodepth=16 \
    --output=result_seqwrite_IDE.txt

Note: If tester want to test 2 Devices with one FIO command, follow Find the TEEIO Device information to find both devices' information, for example, /dev/nvme5 and /dev/nvme6, then set FILENAME=/dev/nvme5:/dev/nvme6.
