With VMD enabled In UEFI, what does these numerials mean in Intel Rapid Storage Technology settings?

Hi,

In the UEFI of my Gigabyte B760M GAMING X AX DDR4 mother board, the SATA Controller and the CPU-linked M.2 NVMe socket (BDF 0/6/0) are mapped to VMD as root ports. See this picture:

Two WD HDDs are connected to the SATA4 and SATA5 sockets on the mother board (all at SATA III speed) and one PCIe Gen4 NVMe SSD is connected to the CPU-linked M.2 socket (PCIe 4.0).

My question is:"With the above two ports mapped to VMD, what do these marked numerals in the picture below mean in the settings of Intel Rapid Storage Technology?"

Hello drkh, 

 

You're very much welcome. And to answer your question, you are correct. The "0.4" and "0.5

 next to SATA, and "1.0" next to the PCIe are most likely port identifiers assigned by the motherboard manufacturer within their implementation of Intel RST and VMD.

 

While Intel VMD oversees the mapping and management of storage devices, the exact port numbering convention you see is determined by the motherboard firmware, which varies between manufacturer.

 

For a much more definitive confirming of this naming scheme, I would recommend reaching out to GIGABYTE, as they can provide insights into their specific BIOS design and naming logic.

 

If you have further questions, kindly let me know.

 

Best Regards,

Hello drkh,

 

Thank you for reaching out. Let me clarify the details as much as possible regarding your observation.

 

In the UEFI/BIOS of your GIGABYTE B760M Gaming X AX DDR4 motherboard, the entries you're seeing in Intel Rapid Storage Technology typically represent the connections and channels for your storage devices as mapped under Intel VMD (Volume Management Device).

 

The SATA 0.4 and SATA 0.5 correspond to the specific SATA ports (SATA4 and SATA5 on your motherboard) to which your HDDs are connected. The numbering format may be manufacturer-specific and not standardized. While your PCIe 1.0 indicates the CPU-linked M.2 NVMe socket which is mapped under VMD and where your PCIe Gen4 NVME SSD is connected.

 

Given the potential variance in how motherboard manufacturers implement these mappings and naming conventions, this is likely specific to Gigabyte's implementation of Intel RST and VMD.

 

For further clarification regarding this, I recommend reaching out to GIGABYTE for further information.

 

If you have further questions regarding Intel RST features, please let me know

 

I look forward to your response!

 

Best Regards,

Thank you very much.

If I understand correctly, you mean that the "0.4" & "0.5" next to SATA, and the "1.0" next to PCIe are port numberings given by the mother board manufacturer, not by the VMD controller (this is my quess).

Is that correct?

Thank you again for helping me. I do apreciate it.

 

Now I don't need to worry about seeing my PCIe 4.0 SSD relegated to PCIe 1.0 in VMD
