Notes:
(a)
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
when connected to another NVIDIA InfiniBand product.
(b)
The non-operational storage temperature specifications apply to the product without
its package.
