how to install opnsense on a RAID1 of SSDs

[vigilian]

Hi,

I will make a tutorial about it but I'm not so familiar with FreeBSD and certainly not with Opnsense.
What would be your advices on how to do it? Should I create a RAID from the live image first then reboot into the installation mode?
What kind of raid should I use? Should I use mdadm method or should I use the ZFS method?
Just enlighten me on how to do it the best way possible . It's nothing fancy, just a couple of samsung EVO 250G .

EDIT: After ahving some reading of the FreeBSD handbook and noticed finally the GEOM option on the installer, the configuration and the installation was full Auto . Sorry to have missed that.

In case of hardware raid, the raid is managed by the raid controller, and the (mirrored raid) disk appears to higher levels, everything above bios, like the OS Freebsd, as a single (virtual) disk.

If this is the case, the OS will have to know nothing about the fact that it is running on a raid disk.

If case of software raid, this would be rather different.

Is Intel Rapid Storage Technology (RST) software raid or hardware raid? I think it is a hybrid. On my Linux systems the OS is aware that the raid array is an array and not a single physical disk.

just to specify I did  go with a higher level of raid through mdadm on the bare metal server which host then the qcow2 file from opnsense vm.
