Hardware and Performance / Re: intel e810 qsfp28 breakout with 8x virtual lan interfaces?
« on: September 26, 2023, 02:24:04 am »
First of all, thank you vpx23!
Little Update from my side:
I went with the E810-CQDA2 , before reading vpx23´ answer :/ and overlooking the limitation in my own research.
I can confirm that the card is fully working with the ice driver of OPNsense 23.7. It is also possible to turn on the "breakout" mode eather with the epct(64e) tool using the cli or on most mainboards directly.
I am using an ASRock Rack B650D4U-2L2T/BCM with a ryzen 9 7950x.
With the current card i can turn on the 2x4x10G Mode which results in 8 interfaces (ice0-7) that work with "BlueLan 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout" cables. The single links are limited to 10G in that case. It is enough for my needs since i mainly needed 8 interfaces.
Unfortunately the manual of the ASRock Rack B650D4U-2L2T/BCM does not speak of bifurcation, but there is an option inside the AMD PBS submenu called PCIE/GFX Lanes Configuration that can be set to x8x8. Since the board does not have another 8x pcie slot I am hopefull the E810-2CQDA2 will work in that and allow 2x4x25G then.
I might be able to confirm that at some point, since i am building 3 systems.
