SCSI disk driver request queue
The SCSI disk driver maintains a queue of disk requests
to be sent to the disk controller. The length of this queue for
each disk is controlled by the SDSKOUT parameter.
If a process sends too many requests to the driver, it will put the
process to sleep until a free slot in the queue is available.
``Tuning the number of SCSI disk request blocks''
for details of how to monitor and tune the performance of
SCSI disk request queuing.
