Mooks, I apologize for that. The side you are connecting is going to call for this cable then - N170M P110M is 621MM (25.7in) long  N170M is 731MM (28.7in) long 
Hi, I am installing a Perc H700 in my Dell R710 which has a 4 drive 3.5" Chassis.  The R145M Cable does not work with this configuration because it is too short and the backplane right angle connector needs to be flipped. Does anyone know what the part number would be for the correct cable for this configuration?
