The run_fio_test.sh script will +call the SPDK setup.sh script to unbind NVMe devices from the kernel driver and bind them to the uio driver. +We include a sample fio configuration file that includes the parameters we use in our test environment. +The run_fio_test.py will append the NVMe devices to the end of the configuration file. The number of +NVMe devices used is specified using the num_ssds parameter. + +Usage: ./run_fio_test.sh |
