I believe I've found the part numbers incase anyone else comes across this: R510 SAS-A Cable  P/N: T520P R510 SAS-B 8HHD Cable P/N: K426P 
I have 3 R510's that have H700 RAID cards in them, and I'm swapping those out for the SAS 6/iR controllers (for the JBOD support).  This requires different cables but I'm not sure of the model/part number for these cables, and how specific they are to the R510.  I need both cables for ctrl0 and ctrl1 ports on the SAS 6/iR.  Where would I be able to find the part number and a place to order from?
