i am connecting to this thru VMWARE on ISCSI, all of a sudden the connection goes away at night and my machines are stuck,  i contacted VMWare said no issues from their side but major latency, 
 
i was hoping someone can give me a direction on to how to check if the latency is caused by NAS box or switch.
