The run_fio_test.sh script will 7*cc439ec2SJohn Kariukicall the SPDK setup.sh script to unbind NVMe devices from the kernel driver and bind them to the uio driver. 8*cc439ec2SJohn KariukiWe include a sample fio configuration file that includes the parameters we use in our test environment. 9*cc439ec2SJohn KariukiThe run_fio_test.py will append the NVMe devices to the end of the configuration file. The number of 10*cc439ec2SJohn KariukiNVMe devices used is specified using the num_ssds parameter. 11*cc439ec2SJohn Kariuki 12*cc439ec2SJohn KariukiUsage: ./run_fio_test.sh 13
