This parameter specifies the number of stripes per queue used by the FMS file striping system.
When FMS writes a record to a striped file, the record is first divided among the queues. Within each queue, the record is then divided among the stripes. The total number of disks running in parallel for each record transfer is the number of queues times the number of stripes.
FMS uses this two layer file striping system to accommodate machines which have distributed memory. By running separate queues in each memory region, data is automatically transferred to the region where it is required.
The maximum number of stripes per queue is 10. If you want to further stripe the files, use multiple queues.
