Calculation to establish FA port queue depth

We have been doing some analysis on our SAN and on one particularly busy VMAX, we see that the queue from the FA hits 1024 and stays there for some time.

I know the FA port queue depth isdependant on how many WWN's are logged onto the FA CPU amongst other things but I need the calculation to help me establish the bigger performance picture for these affected systems.

Did you see this? I believe all I/O ends up in a queue. The queues are just buckets showing how much i/o is waiting in a certain millisecond range. I think....
