Notes:
(a)
If your target application for this crypto-enabled card will utilize 100Gb/s or higher
bandwidth, where a substantial part of the bandwidth will be allocated for IPsec traffic,
please refer to the NVIDIA BlueField-2 DPUs Release Notes document to learn about a
potential bandwidth limitation. See Related Documents section for details on accessing
the document.
(b)
The BlueField-2 DPUs supplement the IBTA auto-negotiation specification to get
better bit error rates and longer cable reaches. This supplemental feature only initiates
