    There is a average disk queue counter on the drive stats.  To get good response time from the drives, the queue should be low, 1 or 2.  To get the maximum throughput from the drives, you need more IOs queued, but the response time will suffer.  There is no setting for this.

    That can't be correct.  Something is wrong.  I would suggest opening a case.  Maybe you need a SE/SPA update.

    In SPA's diag view, you get the avg queue depth for each disk but dont know if its correct or not.
