ASUS Hyper M.2 PCI-e X16 V2 Expansion Card and Support for RAID on CPU

[tle]

I am doing homework for a PCI-e 4.0 X16 card to host many M.2 NVMe SSD in RAID config for my Blackbird /w POWER9 V2 8-core box.

I learn that the ASUS Hyper M.2 PCI-e X16 V2 Expansion Card is one popular choice amongst AMD Ryzen Threadripper platform.

I would like to ask if the Blackbird offers the similar RAID on CPU support? Is there any pro-sumer/enterprise product that offer PCIe 4.0 NVMe SSDs RAID?

Here is a list of working PCIe to M.2 Adapters.
AFAIK, there is no PCIe4 card out there. And IIRC, the Asus card is only partially working (at best), because of the missing PCIe switch. A PCIe switch is needed to get all NVMe slots working.

I was looking for this card too but could not find a vendor for that. I thought this card only sold together with a Threadripper main board...

THX :-) Is was mixing up this with the MSI M.2 Epander Aero (for 4 M.2 SSDs) which I couldn't find to buy at Amazon or my local computer stores (it was mentioned it ct 3.2020 page 77):
