    Quick update: installation and configuration was a breeze and everything is working great!
    The connection is stable and I'm getting ~9.6 Gbps of measured throughput sending data to an NVMe write cache on the storage server from both Windows and Linux, which is in line with what I expected based on the NICs, transceivers, and network switch involved.
    Good stuff!
