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.

Unfortunately, the mini-SAS cable with the model number you provided(NEDDDF-N904, NEDDDF-N901, NEDDDF-N903) could not be found on Amphenol’s official site.↓ https://www.amphenol-cs.com/
I’m sorry, but could you please check the model number again?
Also, I understand you need to support sideband signals, are the following products compatible with Orin DevKit?

This cable was designed for the devkit so it may not be advertised as a standard cable on their website. You should reach out to their local Amphenol contact directly to inquire and purchase the cable. Thanks.
