Detailed Product Description

NVIDIA ConnectX-7 MCX75310AAS-HEAT 400G NDR Smart NIC

NVIDIA Mellanox ConnectX-7 MCX75310AAS-HEAT 400Gb/s NDR InfiniBand Smart Network Adapter with inline encryption and PCIe Gen5 support.

Product Overview

The NVIDIA ConnectX-7 MCX75310AAS-HEAT is a high-performance 400Gb/s NDR InfiniBand smart network adapter engineered for AI factories, scientific computing, and hyperscale cloud environments. This single-port adapter delivers exceptional throughput, sub-microsecond latency, and hardware-accelerated inline security with comprehensive offload capabilities.

Key Features & Performance

NDR InfiniBand 400Gb/s (compatible with HDR 200G/EDR 100G)
PCI Express Gen5.0 x16 host interface
Ultra-low latency with hardware-based reliable transport
GPUDirect RDMA & GPUDirect Storage for GPU-accelerated workloads
In-Network Computing with SHARPv3 collective offloads

Security & Offload Engines

Inline IPsec, TLS, MACsec encryption/decryption (AES-GCM 128/256-bit)
Secure boot with hardware root-of-trust & flash encryption
ASAP2 (Accelerated Switch and Packet Processing) for SDN
Connection tracking, flow mirroring, and header rewrite
Zero-Touch RoCE and overlay network acceleration (VXLAN, GENEVE)

Advanced Technology Accelerators

The ConnectX-7 MCX75310AAS-HEAT incorporates NVIDIA's latest in-network computing engines to offload critical data path tasks from the CPU:

RDMA & RoCE: Zero-copy data movement, NVMe-oF offloads including NVMe/TCP
Timing & Synchronization: IEEE 1588v2 PTP with 12ns accuracy, SyncE, time-triggered scheduling
Virtualization & Multi-Host: SR-IOV, VirtIO acceleration, support for up to 4 independent hosts
Data Integrity: T10-DIF signature handover, block-level XTS-AES 256/512 encryption

Frequently Asked Questions

What is the main difference between MCX75310AAS-HEAT and other ConnectX-7 adapters?

This model is a single-port NDR InfiniBand HHHL adapter equipped with full inline security engines and PCIe Gen5 x16 interface, primarily targeting HPC and AI clusters requiring 400G per port.

Does it support Ethernet mode?

Yes, ConnectX-7 supports dual protocol (InfiniBand / Ethernet), but MCX75310AAS-HEAT is typically InfiniBand-focused. For Ethernet-only or dual-protocol needs, please consult the VPI ordering guide.

Is this adapter compatible with PCIe Gen4 servers?

Yes, PCIe Gen5 is backward compatible with Gen4 slots, but will operate at Gen4 speeds (max 200Gb/s per port effective bandwidth limited by host).

Pre-Sales Checklist

Verify server PCIe slot type: HHHL & x16 Gen5/Gen4 compatible
Confirm InfiniBand fabric speed (400G switch ports required for full NDR)
Check OS driver availability (in-box or download from NVIDIA)
Review cooling and power requirements with your chassis specification
Request quotation with origin warranty terms from Starsurge
