NVIDIA Mellanox MCX75310AAS-NEAT ConnectX-7 VPI Network Adapter Card

NVIDIA MCX75310AAS-NEAT is a ConnectX-7 VPI (Virtual Protocol Interconnect) network adapter card configured for ultra-high-speed data center cluster infrastructure. It delivers up to 400 Gb/s of throughput over a single physical network port using either the InfiniBand or Ethernet protocol. The specific "AAS-NEAT" suffix highlights that the card has Secure Boot Enabled but Crypto features (like hardware line-rate encryption) Disabled, and it ships with a tall bracket.
