what cable for a H310 RAID card on a Dell R710?

Aug 2, 2017
I just ordered on ebay a H310 card for my R710 so that I can flash into IT mode so that I can let FreeNAS play nicely with my drives and overcome the 2TB limitation.
I don't have experience at all with backplanes, SAS connection and basic server related hardware.. so I wonder if someone knows if I can still use the original cable connecting the original card to the backplane, a Dell Perc 6/i - E2K-UCS-61(B), with the new H310 card. Otherwise could I please be pointed to the necessary cable (lenght included)?

Another thing I couldn't figure out: can I place the card in the same slot?

I'm pretty sure this has been done plenty of times before by many of you :)
Many thanks!
I just ordered one the other day for a R710 also. The card will not work in the dedicated storage PCIe slot to my knowledge.

If I remember correctly, the backplane in the R710s just uses a standard SFF8087 port, while the Perc6i uses a 8484 port I think. From the pictures, I'm assuming you will need a SFF8087 to SFF8087 cable like https://www.newegg.com/Product/Prod...VkFp-Ch2bNA2WEAQYBCABEgJArvD_BwE&gclsrc=aw.ds
