I believe num_disks has to do with the number of I/O threads that are spawned and num_large has to do with the number of outstanding I/Os that are targeted to be issued.

For what I use the tool for (I/O bandwidth testing) I generally run the sequential workload to get a best possible data point and then use the rand workload to get numbers closer to what a PQ workload would be.
