Carl, Specifying them as separate jobs will do what I expect. However, in this case, I am seeking to know how much performance and how many devices can a __single__ FIO process can drive. If my above configuration is correct, then, for some reason, the single process doesn't increase with more devices at its disposal, not as I have seen from another benchmark tool - which is puzzling. I am curious to understand why.
