iops with portperfshow

Is there any way for get the IOPS per port of a SAN switch ? I know the portperfshow command, but this command only shows the MB/s.

I want to catch the culprit of a problem in performance of our SAN (storage array), but I don't have access to the servers individually.

Please, provide me any clue according your experience.

the comfortable methode to get IOPS counter, is i.e. by VMware Guest OS trough the VMware Hypervisor.

Another solution is unknown to me.

No, portperfshow can't help you. If your switch/fos support it - you should use flow monitor. If not - then either host side tools, or expensive third party stuff like JDSU and VI.
