How fio works

The first step in getting fio to simulate a desired I/O workload, is writing a job file describing that specific setup. A job file may contain any number of threads and/or files -- the typical contents of the job file is a global section defining shared parameters, and one or more job sections describing the jobs involved. When run, fio parses this file and sets everything up as described. If we break down a job from top to bottom, it contains the following basic parameters:
