no clustering, standalone machine.   and in response to the below statement I've looked at the disks and paths and don't see the same behavior as I'm seeing on these 4 charts

one opinion is that the the RDup  Network Traffic is not the problem. Looking to see which resource had the greatest impact in percentage looks like the queue length. 
So with this being the only source of data, it looks like the queue  length caused the response time which impacted the RDup network traffic.

In this case, load balancing your disks may be the most appropriate response.

Or it could be something else – something which isn’t even on the chart such as CPU utilization or memory resources. One couldn’t know for sure without more data analysis.
