Comprehensive Product Overview

The MCX75510AAS-NEAT is a NVIDIA Mellanox ConnectX-7 smart network adapter optimized for next-generation 400G high-speed networking. It features one OSFP (Octal Small Form Factor Pluggable) port, supporting wire-speed 400Gb/s NDR InfiniBand and 400GbE Ethernet, with backward compatibility for HDR/EDR/FDR InfiniBand and multi-speed Ethernet.

Built on PCIe 5.0 x16 interface (32GT/s, backward compatible with PCIe 4.0/3.0), it delivers full line-rate performance for high-throughput, latency-sensitive workloads. Integrated hardware acceleration engines include RDMA (RoCEv2), GPU Direct RDMA, NVMe-oF offload, and ASAP² for software-defined networking, drastically reducing CPU overhead.

This adapter comes in an HHHL form factor, including both tall and short brackets for flexible server deployment. With Secure Boot enabled (crypto disabled variant), wide temperature tolerance (0°C to 55°C), and enterprise-grade reliability, it’s ideal for 24/7 mission-critical AI, HPC, cloud, and storage infrastructures.

Frequently Asked Questions (FAQ)

Q1: What’s the difference between MCX75510AAS-NEAT and MCX75310AAS-NEAT?

A: MCX75510AAS-NEAT is Socket Direct-ready (supports PCIe x16 Gen 4.0 extension), while MCX75310AAS-NEAT lacks Socket Direct capability. Both are crypto-disabled, Secure Boot-enabled 400G OSFP adapters.

Q2: Does it support both InfiniBand and Ethernet?

A: Yes. VPI technology auto-negotiates between NDR InfiniBand and 400GbE Ethernet; backward compatible with older InfiniBand/Ethernet speeds.

Q3: Is it compatible with PCIe 4.0 servers?

A: Yes. It natively supports PCIe 5.0 x16 and is backward compatible with PCIe 4.0/3.0 slots (reduced speed for older PCIe generations).

Q4: Does it support GPU Direct for AI training?

A: Yes. Fully supports GPU Direct RDMA and GPUDirect Storage to accelerate NVIDIA GPU cluster communication and storage access.

Q5: Are brackets included?

A: Yes. Both tall (full-height) and short (low-profile) brackets are included for flexible server installation.
