Hi all!

I am very interested in the performance data of BlueField’s embedded switch, which is also refered to as PCIe switch or eSwich. However, I cannot found these information from the documents:

  1. The bandwidth of BlueField-2’s eSwitch
  2. The PCIe version supported and lanes of eSwitch

Hope someone can help, thanks!

Hello,

  1. The bandwidth of BlueField-2’s eSwitch

Technical, based on the type of DPU you have (25/100/200) You can check the datasheet (https://www.nvidia.com/content/dam/en-zz/Solutions/Data-Center/documents/datasheet-nvidia-bluefield-2-dpu.pdf), you should be reaching rate line (results may varies based on deployment(s)
We do not release official performance (white papers) however, if that helps, you can review performance reports we have posted for DPDK/Bluefieldfromhttp://fast.dpdk.org/doc/perf/DPDK_22_03_NVIDIA_Mellanox_NIC_performance_report.pdf

  1. The PCIe version supported and lanes of eSwitch

You will need to check the FW RN according to the part# of the DPU for PCIe Gen/Width support.
