- The NVIDIA ConnectX-8 SuperNIC offers next-generation 800G performance.
- Optimizing device queues, tuning ports to NUMA nodes, and workload placement are essential for achieving 800Gbps speeds.
- The configuration resembles NVIDIA GB10 ConnectX-7 200GbE networking setups.
- Keysight's IxNetwork tool enables high-accuracy, low-layer testing of network devices.
- The ConnectX-8 achieves 1.6Tbps L1 bandwidth using PCIe Gen5 servers.
- Testing 800GbE 51.2T switches requires sending and receiving at 800GbE speeds.
- The ConnectX-8 will be used alongside NVIDIA's B300 Blackwell Ultra GPUs in the future.
- Current PCIe Gen5 servers limit performance, but PCIe Gen6 support is expected in 2026.
- The ConnectX-8 enables 800GbE speeds on current-generation servers typically limited to 400GbE.
