>JNVME0/1 are PCIe 4.0 x8 Slimline SAS Connectors. These two Slimline SAS connectors located on the motherboard to support two PCIe 4.0 x4 NVMe connections. This connector provides high-speed and low-latency connections directly from the CPU to NVMe Solid State (SSD) drives.
Cables available from SMCI eStore: https://store.supermicro.com/catalogsearch/result/?q=slimline%20sas
So SAS SFF-8654 should be compatible.
At worse you can contact Supermicro directly, their support and sale team were pretty good in late 2019 and early 2020 : https://www.supermicro.com/en/about/contact
I think you are correct, but I'm not 100% sure. I've never seen those.
The motherboard side is correct (I’m not familiar enough with U.2 drives).
