Proxmox doesn't like my HW raid

I've just built a server for virtualization and tried to install Proxmox 6.2-1.

However, I ran into a problem.

AsusRock Taichi x399

2 Raid Arrays:

RAID 1 (2x 1TB NVMe)
RAID 1 (2x 4TB HDD)

During install, Proxmox (Version: 6.2-1) gives me the option to install to either of the NVMes. I'm rather puzzled by this.

It should show me 1 NVMe and 1 HDD, since I've setup the RAID in the BIOS/UEFI. Yet, I do not even see the harddisks, and instead of one NVMe, I see both. Maybe I'm missing something here, but the current situation strikes me as rather odd.

Any help woud be highly appreciated.
 
Think so as well.
Remove the configuration from BIOS and use the disks/media as JBOD for LVM or ZFS to achieve the same functionality.
 
Thanks for getting back to me.

I have definitely lost touch with consumer electronics. (And there's no entry "Create fake RAID Array" in my BIOS. :) )
20 years ago my Asus MB had a RAID Controller and it just worked. Apparently these days MB manufacturers add half-backed solutions to their products.
I saw RAID in the BIOS and naturally thought it's a RAID. I mean what else would it be? (Note to myself: Hmm, apparently a fake RAID. Still, why would someone put a RAID there, if it can't be used?)

Too bad, I rather would have used a HW RAID. It's cleaner IMO. But no matter, I've used SW RAIDs numerous times before. Although I don't think I need ZFS for 2 simple RAID1 arrays. ZFS is rather brutal when it comes to memory. I have 128GB in that box and I want to use most of it for VMs. With ZFS a good chunk of that memory will be used just for the filesystem. That's perfectly valid for a NAS, but not for a virtualization machine.
 
It is a raid, but only works with certain (mostly Windows) OS.
That's why the call it fake-Raid.
 
Aha, ok. Good to know. I usually worked with enterprise storage subsystems, thus my knowledge in the home market is very limited.

Yeah, I guess SW RAID it is. I doubt that a $400 RAID controller will make much difference in this setup anyway. As I said, I find it more convenient, that's all.
 
You can get decent raid controllers on eBay.
I have used perc5i and perc6i from dell. Those have limits on disk sizes though.
So you likely should look into a per h730 or similar.
Basically those are LSI based raid cards which I can highly recommend.
 
I think that's too complicated then. I would actually need 2 controllers: one for the NVMes and one for HDDs. Nah, if my board can't handle a simple RAID1, then I'll go with the SW solution.

If I had 20 HDDs and wanted to use RAID-50, I'd certainly go for a HW solution. But I won't invest money for 2 simple RAID1 arrays.
 
Oh sorry. I forgot about you using nvme devices. Yeah, better go with SW. These controllers aren't what I would call affordable ;)
