Supermicro X11SCZ-F and AOC-SLG3-2E4T

[PolySerg]

Hi everyone!

I am going to use Supermicro X11SCZ-F. And I also want to have some U.2 nvme SSDs.

The AOC list of the board has a validated card (AOC-SLG3-4E2P - a switch) , but AOC-SLG3-4E2P has four ports... I do not need four ports The two port device is enough for my goals. There are two devices made by SuperMicro - AOC-SLG3-2E4 (a switch) and AOC-SLG3-2E4T (a retimer). You can see a storage cards list here. I am going to start with one nvme ssd and probably will add another after a while.

Which one will definitely work with X11SCZ-F mb?

Please help me to choose the correct one. Thanks a lot!!

The P is the safe (expensive) bet (switch), the retimer might/should work and is a lot cheaper... but nobody guarantees it does.
For me they most often work fine, but i also had a board where it didnt.

AOC-SLG3-4E2P = 4 internal lanes per port • Supports 4 physical NVMe Devices

AOC-SLG3-2E4T = 2 internal lanes per OCuLink port <<<< ??? only 2 lanes ?

Hm I never noticed that ... documentation issue or overlooked limitation?

must be an error, but we should be sure before buying.

I have like 4 of these
Would need to setup a test rig to actually test it...

Edit
In the end it doesnt make any sense - its an x8 card with 2 ports. Why would they artificially limit that to two lanes per Occulink port...

I have just tested X11SCZ-F with AOC-SLG3-2E4 connected to Intel DC P4610 1.6Gb!
They perfectly work together on Win10 Pro and Ubuntu 20.04 srv
There is no need in additional drivers or something else. That's great!
