I want to know how to connect SSD to orin. Especually, I want to know the right Mini-SAS cable spec and NVME SSD interface spec for Drive AGX Orin.

I saw the following comment.

Storage extension AGC Orin

If have the right Mini-SAS cable, could connect NVMe SSD to system through that.

The following comment shows the devkit follows Open Compute Facebook version of the Mini-SAS spec.

PCIe Hot-Plug not working

The cable used on the devkit follows the Open Compute Facebook version of the Mini-SAS spec. Standard Mini-SAS cable would not work as it does not carry some of the sideband signals. Here are the cables from Amphenol which are compatible with the Orin devkit.

1. Doen NVMe SSD interface require U.2 interface?

2. If #1 is true, could you tell me the right cable to connect U.2 SSD to Orin devkit?
   I can find the following Mini SAS HD SFF-8643 - U.2 U2 SFF-8639 cable. Does it work?

3. If #1 is false, could you tell me the suitable interface of NVME SSD and how to connect to Orin devkit?

PCIe (Mini-SAS) could connect to external storage but it need dedicated designed adaptor board.
USB3 PD is easier to access.

@JimWang Thanks!
Could you tell me the model number of “dedicated designed adaptor board”?
I know USB3 PD is easier to access, but R/W speed is slower than PCIe IF.

Or, does Drive AGX Orin devkit have M.2 interface for NVMe?

Hello, @JimWang could you tell me:

Orin devkit has J2, J3 data recorde connectors, which connect M.2 NVMe through PCIe and have necessary power/GPIOs.
If want connect M.2 NVMe through Mini-SAS, need design a similar PCIe-to-NVMe adaptor board, not ready-made one.
USB3 PD is easier to access.

Is #2 is verified already. No information if this cable is Open Compute faceBook version of Mini SAS Spec
