Our old HP AutoRAID had a recommended queue depth of 8, but I don't know what the actual queue size was. At least at that time the IBM deskstar SCSI disk with Linux and an Adaptec 2940 on my home PC was using a queue depth of 250 or so ;-) Did you have a look at what the SCSI guys do about the queue depth? AFAIR formerly you had to specify the depth wehen loading the module/kernel, but then they did an dynamic adjustment. Meybe it's like starting with a huge queue, and once the target complains, set a capping limit on the queue size. I didn't see source recently...
