Hi,
I have SYS-220U-MTNR (2x Gold 6334, 2TB RAM) with 2x NVMe Kioxia CD6-V 6.4TB NVMe PCIe4x4 2.5" and 1x M.2 SATA (Micron 5300 240GB). I setted up RAID 1 on Intel VROC and now i want to install CentOS 7 on the M.2. When i try to do it in the installation i can't see my disk array created on VROC. What should I do to fix it?
Thanks in advance for help!

Re: Supermicro Ultra SuperServer SYS-220U-MTNR
This Intel VROC thing sounds suspiciously FakeRAID. I'd suggest sticking it in to AHCI mode and doing the install using Linux software RAID instead.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

why 7? we are at 9
Re: Supermicro Ultra SuperServer SYS-220U-MTNR
BSht Client requirement is to install 7. In version 9 this problem will not exist?
Re: Supermicro Ultra SuperServer SYS-220U-MTNR
Pure Linux software RAID is better even if a fakeRAID would have support.
I have a Intel-based consumer system (no VROC), where Linux can't see M.2 NVMe drive (which is not part of any "RAID") at all. If I switch SATA controller from "RAID-mode" into "AHCI-mode", then the M.2 drive is detected. This applies at least to kernels of EL8 and EL9. That is, the mere presence of Intel "RST" fakeRAID device somehow masks NVMe-drives.
CentOS 7 is in Maintenance Phase. Only the most critical bugs do get fixes any more and the entire distro will EOL Summer 2024. If you install 7 now, it can be used less than two years. Perhaps that is what your client knowingly expects?

According to Intel this VROC stuff is supported ootb in 7.5 and later. But you have to install the OS in UEFI mode. VROC is not available in Legacy mode.
Re: Supermicro Ultra SuperServer SYS-220U-MTNR
My problem is that i have to install version 7, if not client will not accept our configuration and does not pay for it 
Right now I am downloading newest version of the CentOS 7 (dated 2020) and I hope that works. Is there any clever commands to achieve what i want? 
I have some kind of administrator but he is working remotely and i want to try by myself.

Problem has been solved, it tourned out that my administrator forget about VROC driver
