NVMe cable for dell r640

Hendranata,

With the S140 you would need the cable to go from the backplane to the motherboard, but in order to locate the correct cable i will need to know the specific backplane installed. 

Would you clarify how many drives, the backplane can take?

Let me know.

10 bay slot.

i guess only 4-8 nvme drive supported?

10 x 2.5 inch SATA/SAS/NVMe (up to 8 NVMes)

Below  table have the part number for connecting NVMe on R640 X10 backplane. One of the first 4 cable cab be used for connection NVMe drives on slot 2 to 5 and one of the last 3 cable can be used for connection NVMe drives on slot 6 to 9

7 cable?

are u sure? can u give the picture?

TXC4H, F2V74, MFTWX, FF7PK

4 model but same function ?

6PPNG, 6WD76, 684MR

3 model we can choose one randomly?

You do not need all 7 cables. Only two cables is needed among 7 which I mentioned. 

As I mentioned in my post you need one of first 4 cables(TXC4H, F2V74, MFTWX, FF7PK)  for NVME drives in slot 2 to 5 and one of last 3 cables (6PPNG, 6WD76, 684MR) for NVME drives in slot 6 to 9. 

Yes. these are multiple versions of same cable TXC4H and 684MR are latest cables. 

H755 is not a supported controller on PowerEdge R640. As it is not supported it is not validated, hence we can not guarantee that it will work. 

You can refer below link for a list of supported storage controller for PowerEdge R640

if the backplane has pic-e nvme port cable.. can we use perc H755 ?

if yes then what is the cable part no that support for it?

technically backplane support nvme disk + pci-e cable.. so it should be work with perc H755 right?

Yes. That is correct PowerEdge R640 only support S140 software RAID for NVMe drives

it seems there is no raid card supported nvme disk for dell r640 ?

only s140 with raid sofware can support nvme disk?

Hi Team,

If both MPNs TXC4H, F2V74 have same function. Then we can have a datasheet/Quote for the MPN TXC4H. If possible could you please share the file with MPN TXC4H present?

Thanks,
Sabari

Hi,

this part TXC4H is only a Cable NVMe2-5 X10 Motherboard, Version4, X10
