Hi all,

I recently acquired a R720xd and are looking to get a 10G NIC card for it, more specifically a “daughter card” as Dell calls them.

Found 2 cards:

- Broadcom 57800S, MT09V, 2x 10GbE, 2x 1GbE
- Intel X710 DA/SFP+, 68M95, 4x 10GbE

Obviously the quad port card looks the most appealing to me, the prices are not that different. However, I am not entirely sure about if it’s possible to retrofit in the R720, as it was first introduced in R730.

Would anyone know? I have retrofitted several gen8 nics on gen9 servers on hp, hopefully it would also work on dell? As far as I can see, the connector is a pcie x8

All the doco I read makes no mention, but this video shows a guy putting the Broadcom one you mentioned in a R720XD

If you want to double check contact dell spare parts, they are normally pretty helpful with this sort of stuff!

@DRAGONKZ for completeness, the MT09V card not only "fits" in the R720, it works as well. I updated the firmware of the MT09V in the R720XD, as well as did a iperf3 test in both directions, so I can confirm it actually works. Also, I used Cisco branded DAC cables for the test, and the driver spewed a warning about "unqualified transceiver" or something like that, but still worked perfectly.

That 'guy' is @BLinux btw :)
I guess the word is getting out... :D

Hey all, thanks for your inputs! A little late as getting a son takes a bit of your time away..

It doesn’t surprise me that the MT09V works in the R720, wasn’t it designed for that server? ;)

I am really considering buying a 68M95, everywhere I look, it seems like the dimensions are almost completely identical, it also looks like that the connector simply is a normal pcie connector with a custom slot. As far as I can see too, the slot is pcie 3.0 x8, giving about 8GB/s of bandwidth. That would mean that there would still be enough bandwidth for all 4 10GbE ports. :)
