I'm unclear what my best option is to install Ubuntu 18.04 server onto a new machine.
I initially thought I'd be able to set up a RAID 1 mirror on my 2 SSDs in the UEFI menu and use that. Following the mobo instructions, I set up RAID using Intel RST in the UEFI menus, but the Ubuntu installer doesn't see the RAID mirror drive.
Reading up on this, I can't work out if this is hardware RAID or fakeRAID?
Either way, this doc https://help.ubuntu.com/lts/serverguide/advanced-installation.html#software-raid says that linux software RAID with
mdadm is superior anyway.
All the various pieces about whether the CPU is doing the work of the RAID or not are not self-explanatory, but my take on it is saying, actually a hardware RAID is best - only, is Intel RST RAID hardware RAID or fakeRAID?
And if the CPU isn't doing the work, what is? Some other component on the mobo?
Or have I been reading out-of-date stuff?
