What model? how many disks are part of the LUN? RAID 0,1,S,5, etc?

  I would be interested to know if anybody who is running an EMC disk
subsystem and has altered the queue_depth setting on the hdiskpower devices?

  If so, how did you determine what value to use from the default 8, and how
much of a benefit did you gain in your opinion?
