I would make a statement with good confidence that either the P70/Xeon EFI firmware or Intel's RST Matrix driver (md raid) is broken. It is not possible to run 2 Nvme drives in RAID on Linux on the P70. None of the Linux distributions I tried (Redhat, CentOS, Arch) seems to be able to see the the disk array. RST & Nvme modules and Nvme-CLI are loaded, but mdadm and nvme-cli are unable to see the array. Everything seems to work, as long as the SATA controller is NOT put into RAID mode. Bummer.
P70/Xeon(EFI 2.12) + 2x Intel 6000p Nvme (FW1.0)
