The T320, according to the technical manual, calls for the "adapter", not the "integrated" version. [URL] 
I have a T320 with an S110 RAID and 8 3.5" Hot Plug backplane.    I want to upgrade to an H310 or H710. My Dell rep and server specialist can't find the correct part numbers for the controller or the cable.  They told me to Google it!  I did, and still can't find anything.   PERC H710 Integrated RAID Controller 342-4203 is what they suggested, but this part # is not an integrated card, but a PCIe.   The cable part # may be DJXF7.   Any help is appreciated.
