What kind of NIC cards do you have?
also what is your RAID Controller model?
Did you add any new hardware to the system? was it work fine before, or this is your first time trying the system and face this issue?

Did you tried an older build of DSS, and find out if it works fine with you or give you the same result?

Try if you can to change your cards slots, I mean if you can put your RAID Card in another slot, and the NIC card(s) to another slot(S).
