I do not believe there is a raid capability across the m.2 slots. Would need a m.2 raid controller aoc.What could be wrong with H12SSL-i? I try to create RAID1 for Linux as storage for OS. I use two M.2 ports on the motherboard for it, each port has NVMe SSD Netac NV7000 2TB but on the step when Linux(debian) detects drives during installation, I see only one Netac 2TB and it stops me to create RAID1 array.
On BIOS settings I can see in Security settings a string where Netac 2TB mentioned too. I have question, has it to show two or more strings if more than one SSD connected to motherboard?
I tried to exchange SSD drives, the first one to insert in the second M.2 port and the second one to insert in the first M.2 port, the same situation. I left connected only one SSD drive, still the same situation. Linux kernel is the latest - 6.1
Yes. Two nvme ssd drives for it..and main storage on raid5 with the same model of ssd drives(through extension pcie boards) but I am stuck on the OS installation proccess it yet.you want to install on 2x NVMe in RAID1 ? afaik you have to install on other drive than the two RAID drives.
the two drives are connected to CPU PCIe not RAID controller, so software raid. OS can not started from those drives.I didnt understand your "afaik you have to install on other drive than the two RAID drives." What to do you mean in other words?
Yes, as I said, I have five of them. All running proxmox on a RAID 1 with ZFS on the root volume.you have done this before with the identical-models of SSD & board & CPU ?
I bounced a host to check this: no, I didn't change the firmware source in my installation.have you changed (BIOS) the NVME Firmware source from "Vendor defined" to "AMI Native" ?
All cards I use are Gen3 (except NVMe), I havent seen an issue.i'm fine with PCIe Gen3 speeds. Gen4 stuff is so new and are more expensive - controller, cables, drives..
and that's why i'm asking - will that Gen3 stuff work just fine with H12SSL?
