NVMe for R640
So I have my R640 and it has a SAS/SATA Backplane
I know the P/N for the NVMe Backplane is MWY54. However, I do not know the cables for that connect to the backplane to the motherboard.
I need 0-1 and then 2-5. Not sure why it has to be this complicated but somehow and some reason, it does. Anyways if someone could help me it would be a godsend
I'm tired customer service, sales, technical support transferring me around like it's monkey in the middle.

I dont mean any offense, I am truly just curious as I see these types of questions very often on the forums, people want to make nvme systems into sas/sata, and sas/sata systems into nvme (among other things). why wasnt the system ordered with nvme to begin with if thats what is needed?

@DELL-Rey G
I think it is crazy you are working for Dell and asking that question without providing support.

Hello,
We don't support field changing of backplane configuration. There are no Kits for it and we would have to try to piece part it together which would lead go possible wrong part or not all correct parts and lead to frustration.
With that said these are all the NVME cables I see listed:

As I said, i was just curious, I meant no offense. As for the support, some of us here at Dell have knowledge of certain areas and we volunteer our time on these forums to help people where we can. I couldnt help much in your case since part numbers change, and sometimes a customer will say I have X and trying to accomplish Y, and we provide a part number(s) and then something in the scenario was not communicated correctly and that part number doesnt work and then a customer can get mad. I tend to avoid making suggestions when it comes to parts unless I have a running configuration exactly like the customer is trying to achieve. In your case, I only have a 2 sas/sata+8 nvme drive config. I understand your frustration in trying to find the correct parts, but unfortunately we arent usually given information that says "if you are trying to add/change parts from this config to that config, you need x,y,and z".

I believe this is depending on config, it will be 2-9 or 0-9 NVME..
To go from 8 (figure 13) to 10 (figure 3), (referring to the manual), you need to add cable M7YXV and card TJCNG.
