BIOS can detect NVMe drives. We set up UEFI boot mode, SATA in "raid mode", NVMe mode in "raid only", S140 still doesn't detect any NVMe drive.
Will S140 work even without the cable? The diagram I supplied in my earliest message shows that it requires its own cabling. Can you help find out the Dell part number for the right S140 cable on Dell 10-bay chassis?
Good to know that S140 cable is NOT required for S140 to detect NVMe drives.
The site somehow doesn't allow me to upload photos - no permission.
Under S140 Physical Disk Management it shows 'Unable to dispaly physical disks as there are no disks currently detected" even though BIOS Device List can detect the drives that are installed in bay 2 and 3,
On Physical Disks page in BIOS did you selected Interface Type as NVMe. By default this page will have Interface Type as SATA. This error message is expected for SATA as there is no SATA drive connected to S140.
if we still using mini sas HD cable connected into S140 onboard.. then we use NVMe u.2 2.5" in front bay.. what will happen? it is working? yes we set SATA embedded: AHCI mode (not raid mode)..
That will depend on the system that you are one. Not only the on board PERC S140, you will still the communication chain, in such backplane NVMe support and NVMe cable.
I believe you are looking for particular info in multiple post, trying to obtain public user opinions.
I hope there is no confusion, as in server model, backplane capability, PERC compatibility and cabling.

On Physical Disks page in BIOS did you selected Interface Type as NVMe. By default this page will have Interface Type as SATA. This error message is expected for SATA as there is no SATA drive connected to S140.

Very interesting, thanks Shine.
There's no "Select Interface Type" option under page "View Physical Disk Properties".
The UEFI Driver Version under page Controller Management >> View Controller Information is 5.5.2-0006, is it different from yours?
Kind regards,

Hi Shine,
The BIOS has been flashed to the latest 2.10.0, and the idrac is now 4.40.00.
"Select Interface Type" is still not showing up.
Kind regards,

Hi Shine,I appreciate your reply.
I checked Figure 3 diagram, we don't use PCIE expansion card and we don't use mini card, other cabling are the same.
The cabling should be correct otherwise the BIOS Device List won't detect NVMe drives.
I am confused why our S140 doesn't have the "Select Interface Type" menu shown in the picture you supplied earlier.
My original thought is that we may need S140 cablesbir 10 bay, and now as you mentioned we don't need that for NVMe drives.
Kind regards,

I am not sure why it is not showing NVMe drives
Can you ensure all cabling are proper as per "Figure 3. Cable routing - 10 x 2.5 drive backplane with NVMe" of below link.
https://www.dell.com/support/manuals/en-us/poweredge-r640/per640_ism_pub/cable-routing?guid=guid-97280a84-9e95-4a04-901f-400c88c14645&lang=en-us
Are you having RAID controller and non NVMe drives on the server?

if we still using mini sas HD cable connected into S140 onboard.. then we use NVMe u.2 2.5" in front bay.. what will happen? it is working? yes we set SATA embedded: AHCI mode (not raid mode)..
anyone have tried before?

nvme cable with part no: 0684MR and 6PPNG
do they work with ssd sata as well? or only work with u.2 nvme disk?
