RE: Disk Config With CX6000

The limitation I was referring to is actually on the queue depth. It defaults to 8 per LUN, but can be increased up to 256 to increase throughput to high capacity arrays. Here are some links for more info:

I've heard stories of some other hard limit built into the HPUX kernel that limits IOPS/LUN to a certain capacity, however I have never observed it myself and haven't been able to find any details on the web so I'm not sure if that's true or not.

I wasn't aware of any limitation of IO per LUN on HP-UX. Can you provide more details?
