R740XD2 24 Bay LFF NVMe + SATA backplane
Hello!
Hope all is going well. I'm looking to add NVMe capabilities to my Dell R740XD2 24 Bay LFF server and I'll need to use a different backplane that supports 20x SAS/SATA and 4x NVMe drives. Will you please provide the part number for this backplane? I understand there will be other hardware needed, but this is the big question I have. Thank you!

Hi,
For R740XD(2), it is possible. DPN# PC8TD is the backplane that can do 24X NVMe or 12/12 SATA/NVMe, you can refer to the user guide of cabling here: https://www.dell.com/support/manuals/en-uk/poweredge-r740xd/per740xd_ism_pub/cable-routing?guid=guid-06637506-d7db-43e6-9c15-be4a832d4fbe&lang=en-us.
PS: The user guide might be confusing but understanding how the cabling goes, NVMe support capability is possble with the correct cabling. But I would emphasize that R740XD and R740XD2 hardware configuration are different.

Correction: Looking for the backplane part number that can accommodate: 3.5 inch (x12) Hybrid backplane with NVMe U.2 SSD. Thank you!

Hi,
Usually the server's hardware configuration is out from factory, it is difficult to change the hardware into another configuration as it involves various hardware replacements, especially R740XD2 and R740XD.
After searching through the documentation and parts available for R740XD2, I cannot find any information that the only available backplane for R740XD2 can support NVMe. This is the backplane DPN#, V0THP.
From the user guide, this is the only backplane which R740XD2 supports: https://www.dell.com/support/manuals/en-us/poweredge-r740xd2/PER740xd2_ISM_Pub/drive-backplane-guidelines?guid=guid-5e3026aa-1aee-4c20-af26-144a3c7f9371&lang=en-us

@DELL-Joey C Appreciate it Joey. Then can you please tell me what the backplane part number is for the R740XD 24 Bay SFF server that allows for 4x NVMe drives and 20x SAS/SATA? I assume 8x NVMe isn't possible. Thanks again and will do a thumbs up.
