I recently tested a few SFP+ and SFP28 cards and DACs/AOCs with Unraid, so I thought I’d share my findings in hopes that I can help someone else upgrade to something that is compatible. As you know by scanning through the Unraid Forum and Reddit, it can be hit or miss with SFP+ & SFP28, DACs/AOCs, and Unraid support.
All of the testing was on my own AMD-based Unraid machine. Here’s the specs on Unraid:
Motherboard: Gigabyte B550 AORUS PRO V2, Bios Version F18d, the network cards were place in the second PCIe slot labeled “PCI Express x16 slot (PCIEX4), Supporting PCIe 3.0 x4 mode”
Unraid Version: 7.0.1
Switch: Mikrotik CRS310-8G+2S+IN
10Gbe SFP+ Card: Intel X710-DA2 (Dell Y5M7N)

eBay Link: https://www.ebay.com/itm/134979859540 (sold out already, but there are hundreds of these listed)
I bought it on eBay used for $39.99 USD. Based on my research, Dell branded vs non-Dell branded didn’t make a difference since I read that you can install Intel firmware on both versions. However, I tried upgrading firmware on Linux and Windows 11 machines using the Intel firmware, but ran into errors, so I did not upgrade with Intel firmware. Instead, I used Dell firmware on a Windows 11 host and the upgrade process was smooth (see firmware upgrade section below). Besides the firmware upgrade, I only unlocked the card – see the footnotes for how to unlock a card to work with any brand-encoded cables. Before and after the upgrade and unlock, Unraid 7.0.1 picked up the card with no additional packages needed so it was basically plug-and-play. I unlocked the card before trying it with Unraid, so I don’t know if it would have been picky with the cables below. However, later you’ll see that the locked XXV710-DA2 also did not have any issues with any of the three cables so I doubt I even needed the unlock on the X710-DA2.
Power consumption changes were unnoticeable on my machine. It continued to bounce around 50-60W at the wall.
Cables tested successfully and at full 10Gbe speeds:
- ipolex Colored 10G SFP+ Twinax Cable, Direct Attach Copper(DAC) Passive Cable in Green, 0.5m (1.64ft), for Cisco SFP-H10GB-CU0.5M, Meraki, Ubiquiti, Mikrotik, Intel, Fortinet, Netgear, D-Link
- This was $9.88 USD on Amazon for 0.5 meters.
- 10Gtek 25G SFP28 SFP+ DAC Cable – 25GBASE-CR SFP28 to SFP28 Passive Direct Attach Copper Twinax Cable for Intel XXVAOCBL1M, 1-Meter(3.3ft) –
- This was $15.99 USD on Amazon for 1.0 meters.
- Notice this is a SFP28 cable rated at 25Gbe! It worked perfectly at SFP+ speeds and I have room to grow. I don’t have an SFP28 switch, so I was not able to test it at 25Gbe.
- There is a color selector on the 10GTek product page, I got the “For Intel” option, since this was for Intel Network Cards
- 10G SFP+ to SFP+AOC OM2 3M/5M/7M LSZH 10GBASE Active Optical SFP Cable(AOC) for Cisco,MikroTik,UbiquitiโฆEtc Switch Fiber Optic
- This is from Ali Express from the store “XICOM Store” (Store ID: 1100319020), I got the 10G AOC OM2 20M option
- Shipping to California took 5 business days
- Excellent building materials and packaging. Also, they included transceiver caps at the ends to protect during transit while none of the Amazon vendors did.
- This is an Active Optical Cable (AOC) for longer distances since I needed one for an 18-meter run.
I’d recommend the X710-DA2 + the Gtek SFP28 DAC (Intel version) if I needed a surefire solution. However, see the option below for a 25Gbe card that is just as compatible and only $10 more!
25Gbe SFP28 Card: Intel XXV710-DA2 (Dell HN7J7)

eBay link: https://www.ebay.com/itm/196538640857
I also bought this card a week apart from the V710-DA2 and swapped this into the Unraid machine instead.
Long story short, it works with all three cables listed above and I did not unlock it. I took it out of the eBay packaging and plugged it into the Unraid Machine, and it was good to go! I’m running it with the Gtek SFP28 cable that I mentioned above, but only at SFP+ speeds since I’m still limited by the Mikrotik SFP+ switch.
I don’t see a reason why anyone should go with the V710-DA2 if the XXV710-DA2 is plug-and-play, newer, supports ASPM, can go up to 25Gbe, but can also run at 10Gbe, and is only $10 USD more!
TL;DR, go with the Intel XXV710-DA2 and a Gtek SFP28 cable (intel version) and call it a day.
Power consumption, is also around the same place as before. i.e. 50-60W for the Unraid server at the wall.

As noted above, I’m still trying to figure out why ASPM is disabled. This is the case for both the X710-DA2 and the XXV710-DA2, on both Unraid and Ubuntu 24.04. I enabled PCIe ASPM Mode “L1 Entry” on both motherboards, along with running powertop --auto-tune
but no matter what, I’m still not seeing ASPM enabled via lspci command. Let me know if you have any ideas.
Unlocking a X710 Intel Card to work with any brand-encoded cable
I followed this guide, but simplified the instructions.
As mentioned above, all three cables worked fine on the locked XXV710-DA2, so I don’t think I personally needed to unlock the X710-DA2, but here is how I did it in case you need to unlock yours for your application.
# I was on Ubuntu 24.04, so your instruction can vary
# 1 - Install v710 card in machine (I did not test with XXV710)
# 2 - Clone repo and compile code, repo is kinda old, but code worked fine
git clone https://github.com/bibigon812/xl710-unlocker.git
cd xl710-unlocker/
make
chmod +x xl710_unlock
# 3 get device name
sudo lshw -class network -short
# H/W path Device Class Description
# ======================================================================
# /0/100/1.2/0/2/0 enp36s0f0np0 network Ethernet Controller X710 for 10GbE SFP+
# /0/100/1.2/0/2/0.1 enp36s0f1np1 network Ethernet Controller X710 for 10GbE SFP+
# /0/100/1.2/0/4/0 enp38s0 network RTL8125 2.5GbE Controller
# /0/100/1.2/0/6/0 wlo1 network Wi-Fi 6 AX200
# Above the device name is "enp36s0f0np0", you just need to pick one of the devices even though it has 2 ports
# 4 unlock the card with this command:
./xl710_unlock -n enp36s0f0np0
# EMP SR offset: 0x67f1
# PHY offset: 0x6941
# PHY data struct size: 0x000d
# MISC: 0x6b0c <- locked
# MISC: 0x6b0c <- locked
# MISC: 0x6b0c <- locked
# MISC: 0x6b0c <- locked
# Ready to fix it? [y/N]: y
# That's it, it was pretty straight forward. Then I moved the card to my unraid machine.
Speed Testing
Before, with 1Gbe Cat 6

After, with 10Gbe SFP+
Here is a speed test using the XXV710-DA2 -> Mikrotik -> X710-DA2
Unraid had the Intel X710-DA2 with the cable 10Gtek 25G SFP28 SFP+ DAC Cable to Mikrotik CRS310-8G+2S+IN, then to Ubuntu 24.04 Desktop with XXV710-DA2 with the AOC OM2 cable.

Success! speed went from 942 Mbits/sec to 9.02 Gbits/sec.
Upgrading Firmware on Dell Intel X710-DA2 and XXV710-DA2
To start here is the version on X710-DA2, taken from Ubuntu 24.04. Notice firmware version 9.20.
(base) user@ubuntu-desktop:~$ ethtool -i enp36s0f0np0

I tried using Intel firmware, but kept getting “Update is Unavailable” , so I switched to Dell firmware which only support RHEL and Windows. Luckily, I was already dual-booting Windows 11 and Ubuntu 24.04, so I switched to Windows for the upgrade.

Here is how to upgrade NVM Firmware using Dell Firmware on both X710 and XXV710
- Download the latest Dell Firmware, you can find the link below or do a Google search for “Dell X710 Firmware” to find the latest firmware on the Dell site, since the Dell internal search sucks.
- Download the Update Package for MS Windows 64-Bit
- Right-click the .exe file and click on Run As Administrator

4. Follow the prompts and upgrade, then restart.
Here’s what it looks like back in Ubuntu after the upgrade
