Unexplained read and write latency

From time to time I have very high peaks of write as well as reads latenvy.

FAS3250 8.1.4P7

 

I cannot correlate it to anything.

Here is some data from harvest:

zoomed in to a specific high latency point:

even more zoom:

Maybe throughput correlates a little but I don't think it should have this impact.

 

Any idea what to look for next?
