Controller RAID for Vostro 270

Hi everyone!

​I have a VOSTRO 270 with 2X 1TB SSD (Samsung 870 QVO).​

On this machine there's an Ubuntu Server instance for local project development.

I've tried to install the SSDs in RAID1, but there's no RAID option into the BIOS. I've found a thread that says to enable it by BIOS, but in mine there's not way to do it.

So I've mounted a RAID controller (via PCI-E) but the motherboard doesn't recognize that.

During the boot, even if the SSDs are correctly connected to the controller, the BIOS return a "no bootable device connected", but recognizes during system runtime (I've tried that booting via usb a live OS ISO).

It seems like it doesn't recognize the raid controller during this step (before POST).

Is there a way to make it working? Maybe mounting an official Dell RAID controller? Or it needs a specific BIOS version to work?

I need to make it working in Ubuntu Server 22.

Thanks in advance!
