No Intel Virtual RAID on CPU

Hi there,

I have a new Intel Server System R2208WFTZS with 2 Xeon4114 CPU's and an installed VROCPEMMOD Raid Key (this is the key for 3rd parity SSD'S).

I have installed 2 Samsung PM863a Enterprise SSD drives and have connected the drives with the board with AXXCBL600CVCR (for each drive a cable).

So far so good. I flashed the newest BIOS on the System and the System runs.

But:

I can see the in the volume device Managemnt both SSD's

but in the UEFI Option ROM Control won't appear the

Intel® Virtual RAID on CPU

entry, so cannot build any raid with my SSD drives

What I have already done:

I have changed the VROCPEMMOD Raid Key

I bring System up with only one CPU installed

No effect - I cannot see the entry Intel Virtual RAID on CPU

Any suggestions / ideas?

Thank You

Martin
