No. Seeing high NonRWRequest does not indicate a problem with the drives or unit. The high count is incorrect and erroneous. It can safely be ignored. 

Firmware 5.04.0000.36 and older exhibit the incorrect high NonRWRequest count.   

An upcoming firmware release will correctly monitor NonRWRequest and give accurate results.
