NVMe for R640

Question

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 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.

@Chino de Oro​ Thanks! But what about bays 0-1?

Chino de Oro · Answer

I think it's M026C

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.  I got the server second-hand from a local Datacenter and I am upgrading it.

Augury Solutions · Answer

@DELL-Young E​ Hey!I just need the part numbers for cables 0-1 and 2-5! Also, figure 8 does not show.

DELL-Charles R · Answer

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:

Part Number	Part Description	Functional Description
684MR	ASSY,CBL,NVME6-9,X10,MB,R64,V3	ASSY NVME Cable, (for SM 2.5"x10)

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'.

DELL-Rey G · Answer

Just to consolidate what has been mentioned in this thread, the parts are:
expander MWY54
ASSY,CBL,NVME2-5, X10BP,MB,R640 FF7PK
ASSY,CBL,NVME6-9, X10BP,MB,R640 6PPNG
ASSY,CBL,10BP,EXT,R640 M7YXV (cable that goes from PCIe NVME card to drives 0 and 1)
PWA,CTL,PCIE,EXTDR,ADPT,14G,LP TJCNG (PCIe NVME card)

In the image, there is a 3,5 and 6 cable. my system has these 3 cables, they are 4RN89, 59G4K and GWW87.
note, my system has the sas/sata mini perc.

@DELL-Rey G​  I am struggling as well. is the TJCNG (PCIe NVME card) and cable required if all I need is 4 nvme slots, and 2 sas slots with the mini perc? As far as I can tell I can set it up like Fig. 2? So my question would be, is the TJCNG card only required for A0+A1 nvme or can I just run SAS in those, and NVME in 2-5 or 6-9?

DELL-Young E · Answer

Hello, to assist you, I would just ask for your service tag (assuming you are still maintaining the original configuration). And your ultimate goal might be? Please note there are no upgrade kits available.

Respectfully,

user_259854 · Answer

@DELL-Young E​  Hi, service tag is. I am looking to purchase a NVME backplane and cables to upgrade this server, and 4 others. The end goal is a HCI with 5 servers, each with 3 NVME drives each, 2 SAS drives, and a 25gbe PCIe card for comms between them. Hence the question about TJCNG requirements. Using Proxmox as the VM manager(on mirrored SAS drives), and cephfs for the VM storage on NVME drives
