Anyone with experience with the SABRENT 4-Drive NVMe SSD to PCIe 4.0 X 16 Adapter Card and Proxmox

Anyone have any experience in getting an multi-NVMe/PCIE adapter properly seeing all drives in proxmox?

System Specs:

CPU(s) - 96 x AMD EPYC 7642 48-Core Processor (1 Socket)
Kernel Version - Linux 6.5.11-7-pve (2023-12-05T09:44Z)
Manager Version - pve-manager/8.1.4/ec5affc9e41f1d79

Here is what is seen in Proxmox:

nvme_pcie_drive
nvme_pcie_drive1216×59 9.55 KB

It is only seeing one 2TB drive rather than four 2TB drives… or am I SOL with being able to leverage the PCIe adapter?

I assume the adapter requires support from the motherboard in form of bifurcation.
If available, this feature can be enabled in the BIOS/UEFI. Look for PCIe settings by slot. The used slot needs to be set to something like “NVMe RAID” or it simply appears as “4x|4X|4X|4X”.

Thank you @jode I will check the bios to see, I need to to get into the bios to do some PCIe pass-through settings as well, so will check. The MB is a Supermicro H12SSL-i for reference…
