Hi Jeff,
It is a Symmetrix 8000. I have 38 LUNs assigned to my AIX box running RAID-1. I have tried to find some guidelines from EMC's website with no luck. Thanks.

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

Subject: Queue Depth for EMC
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?
TIA
