LinkJames & MiloResource
The build illustrates how research teams and independent labs can deploy high-bandwidth inference infrastructure at lower cost by avoiding enterprise racks and proprietary Spectrum switches.
James and Milo provide a practical engineering breakdown of running an 8-node GB10 DGX Spark stack. Because each Spark shares ~200G of PCIe across two cages on a ConnectX-7, a single 200G link per node is optimal. The report also highlights real-world firmware and software issues, including USB-C power delivery negotiation quirks and RDMA stability failures under multi-node RoCE workloads on kernel 7.0.
