Supermicro AOC-SLG3-8E2P Octaport NVMe HBA

[JoshDi]

my AOC-SLG3-8E2P has one occulink port for each U.2 channel/drive. never came across any breakout cables nor have I really searched for one. you do have to be careful here because different cables, even with the same end connectors as another, may not work with a specific PCIe card.

Thanks, I must be confused, after checking I noticed that each occulink port is a single x4 channel.

Do you like this card? Did it cause any issues other than the cabling issue you mentioned?

the card is great - it went up by almost 100 dollars because of covid. I use it with VROC (with some more details in my post in this thread). Its rock solid and speeds are super fast. Its way more reliable than my LSI MegaRaid cards that sometimes do funky stuff

I have this card 8port, the 4 port and the 2 port as well. They works well as direct attached no hassle.
The only thing I cannot figured out or find is the cable to support dual-port NVMe drives and to use dual controllers.
SANBlaze has photo showing the SFF8639 to *2 SFF8643 cable is available here: NVMe | sanblaze and SerialCable has the Oculink version here: Gen4 OCUlink x4 (SFF-8611) *2 to x4 PCIe Drive Receptacle (SFF-8639) Cable - Serial Cables

So, question: anyone able to test dual-port nvme drives with dual contollers?

I am interested in dual port as well. Did you receive any additional information or guidance from helpful STH gurus?

I'm going to install the quad-port version (AOC-SLG3-4E2P) into an SC747 chassis ( SC747TG-R1400B-SQ | 4U | Chassis | Products | Super Micro Computer, Inc. ). My research leads me to the understanding that this is going to require swapping my current backplane, which supplies the 8x hot-swap front-loading SATA/SAS drive bays (BPN-SAS-747TQ), with the BPN-SAS-747TQ-N4 backplane, which has 4x NVMe/SATA/SAS drive bays plus 4x SATA/SAS drive bays ( https://www.supermicro.com/manuals/other/BPN-SAS3-747TQ-N4.pdf ).

Has anybody tried a solution like this or used this backplane or a similar one?

I'm also looking at solutions involving mobile racks, which, I understand, already come with backplanes that allow 4x NVMe connections per 1x 5.25" slot.. I've already got 1x DVD+-RW ODD installed and I have 2x 5.25" slots spare.

What board did you put this into? On their page, supermicro said "This product does not work with 3rd party servers. It can only work with validated Supermicro server systems and Supermicro motherboards." from here. Did it work?

Are you using a supermicro board for it? Cant find any info on if they work outside of supermicro boards
