I am working on swapping an R720 8xLFF BP with an R730 8xLFF BP. Looks like all I will need to do is make a custom cable combining the 2x 8pin power connectors on the R720 into the 10pin R730 power cable.

Anyone ever done anything similar? Attached is my pinout documentation I worked out from the boards I have.

I would be afraid the BMC will freak out and not see the drives properly. If you are planning on running an HBA it probably won't matter,but you may have to press a key on a reboot

I want to use 12G SAS drives in this chassis and right angle 8087->8643 cables are hard to come by.

First pass bench test looking good. Used external 12V power supply to r730 backplane 10pin connector. I was able to route the HBA cable and backplane signal wire out one of the empty PCIE cover slots. I am not sure if the "ID" (grey wires) are important but I used a small jumper wire to short them out identically to the original r720 back plane. Seems to recognize my test SATA drive just fine...
