I am interested in designing with a VPX3U-BW5000E-CX7 which is an integrated GPU, NIC on one board. I would like to purchase separate GPU and NIC cards to experiment with the doca_gpu_packet_processing app to do GPUNetIO (GPUDirect) packket reception and orocessing. I have looked at the RTX A2000 for the GPU but would like the most reasonably priced solution for the GPU and NIC that I can prove out this development and then port to the VPX3U-BW5000E-CX7.
Please help.
For concrete part selection/pricing please go through NVIDIA Sales or an authorized partner:
For the doca_gpu_packet_processing example, DOCA doesn’t require a specific GPU/NIC SKU, only that:
1/ NIC side
+ Use any DOCA-supported ConnectX adapter (including ConnectX-7) that appears in the DOCA documentation as supported for DOCA GPUNetIO / GPU Packet Processing.
+ Ensure the NIC and GPU share a suitable PCIe topology (same root complex / switch) so GPUDirect RDMA can work correctly.
2/ GPU side
+ Use a CUDA-capable GPU that supports GPUDirect RDMA and is listed as supported for your DOCA release.
+ Performance level (entry vs high-end) is up to your model complexity and budget; the sample app itself just assumes GPUDirect-capable CUDA hardware.
The most accurate, up-to-date compatibility information is in the DOCA docs, e.g.:
+ DOCA GPU Packet Processing Application Guide (hardware and topology requirements)
For recommendations on the cheapest or best combination that matches your VPX3U-BW5000E-CX7 design, please coordinate with NVIDIA Sales or an authorized NVIDIA partner so they can match parts to your specific system and commercial needs.
