We have a fairly large VMWare installation with 90 physical servers, 25tb of disk, running on a pair of 9585's and an NSC55 disk frame. We have run into some over-subscription issues on the 9500 class frame and are in the process of moving to an NSC55 for the higher queue depth and adapter ports.

   We keep running into a road block with VM, as they recommend setting the queue depth as high as possible, which went from 30 to 64 on the latest release of VM. In an attempt to get around this we have been creating larger and larger luns. Does anyone have experience with this issue and have any recomendation's to offer on lun size's, queue setting's ect.... ?
