I think I might be hitting the IO limits of what my Netapp can deliver, as I have been adding more servers to my cluster and iowait has gone up on each server.
However, how do I quantify this? How can I use Netapp CLI tools to view current IO stats? I am aware of "stats show" but not seeing an "io" object or similar. How do I know what the Netapp is supposed to be able to deliver?
If anyone has more experience with Netapp than I, I would greatly appreciate the help.
