High-performance single-port RDMA adapter delivering 400Gb/s throughput over InfiniBand (NDR400) and Ethernet (400GbE) protocols. Features PCIe 5.0 x16 host interface, OSFP connectivity, Secure Boot, and hardware-accelerated networking for AI, HPC, and hyperscale cloud workloads.
Product Overview
The NVIDIA ConnectX-7 MCX75310AAS-NEAT is a single-port VPI (Virtual Protocol Interconnect) adapter from the ConnectX-7 family, supporting both InfiniBand and Ethernet protocols at speeds up to 400Gb/s. This model features a single OSFP port and PCIe 5.0 x16 host interface, making it suitable for high-bandwidth, low-latency applications including AI training, scientific computing, and cloud data center interconnects.
Important Note: The "AS" variant includes Secure Boot with hardware root-of-trust but has crypto functions disabled. For environments requiring IPsec, TLS, or MACsec inline encryption offload, please consider the "AC" variant (MCX75310AAC-NEAT).

PCIe Half Height, Half Length (HHHL) – 68.90mm x 167.65mm
Important Variant Note: The MCX75310AAS-NEAT (this model) has Secure Boot enabled but Crypto disabled. If your deployment requires inline hardware encryption/decryption for IPsec, TLS, or MACsec, please select the MCX75310AAC-NEAT variant which includes both Secure Boot and Crypto engines.
Considerations:
Port Density: This is a single-port OSFP adapter. For dual-port 200GbE/NDR200 configurations, consider MCX755106AS-HEAT
Cables & Transceivers: Use OSFP-compatible cables or optical modules for 400GbE/NDR400
Bracket Options: The card ships with a tall bracket; a short bracket is also available for low-profile chassis
Server Compatibility: HPE customers can order as HPE P45641-B21 or P45641-H21
Buyer Checklist
Confirm your server has an available PCIe 5.0 or 4.0 x16 slot (physical and electrical)
Determine if crypto offload (IPsec/TLS/MACsec) is required; if yes, order the MCX75310AAC-NEAT variant instead
