NVIDIA ConnectX-7 NDR 400Gb/s InfiniBand Smart Adapter
Model: MCX755106AS-HEAT | PCIe Gen5 Dual-Port 400GbE / NDR
Ultra-low latency RDMA networking for AI factories, HPC clusters, and hyperscale cloud. Supports InfiniBand NDR (400Gb/s) and Ethernet up to 400GbE. Features In-Network Computing engines, hardware security acceleration, and GPUDirect Storage readiness.
Product Overview
The NVIDIA ConnectX-7 family redefines data center interconnectivity with up to 400Gb/s bandwidth, hardware-based reliable transport, and advanced in-network computing. The model MCX755106AS-HEAT belongs to the ConnectX-7 VPI adapter series supporting both InfiniBand (NDR/HDR/EDR) and Ethernet (400GbE to 10GbE).
Built for AI, scientific computing, and modern software-defined storage, it delivers sub-microsecond latency and frees CPU cores via acceleration engines for security, virtualization, and NVMe-oF. With PCIe Gen5 host interface, this adapter maximizes data movement for GPU clusters and high-frequency trading environments.
Key Features
  • Ultra-high throughput: Dual-port NDR 400Gb/s InfiniBand or 400GbE, PCIe Gen5 x16
  • In-Network Computing: SHARPv3 collective operations offload, rendezvous protocol offload, on-board memory for bursts
  • Hardware Security Engines: Inline IPsec/TLS/MACsec AES-GCM 128/256-bit, secure boot with hardware root-of-trust
  • Precision Timing: IEEE 1588v2 PTP (12ns accuracy), SyncE, class C G.8273.2, time-triggered scheduling
  • Accelerated Storage and GPUDirect: GPUDirect RDMA, GPUDirect Storage, NVMe-oF offload, T10-DIF signature handover
  • SDN and Overlay Offloads: VXLAN, GENEVE, NVGRE, programmable flexible parser, connection tracking (L4 firewall)

Frequently Asked Questions
What is the difference between NDR InfiniBand and 400GbE mode?
NDR includes SHARP, adaptive routing, and hardware reliable transport natively; Ethernet mode uses RoCE for RDMA. ConnectX-7 supports both.
Is MCX755106AS-HEAT compatible with PCIe Gen4?
Yes, backward compatible with PCIe Gen4 and Gen3, but at reduced lane speed.
Does this model support Multi-Host?
Yes, ConnectX-7 supports NVIDIA Multi-Host technology (depends on SKU and cabling).
What encryption is accelerated inline?
IPsec, TLS, and MACsec (AES-GCM 128/256-bit), all offloaded from CPU.
Installation Notes
  • Ensure proper airflow in server chassis when using high-power transceivers
  • Use firmware validated by Starsurge or NVIDIA
  • Install latest MLNX_OFED driver for full offload capabilities
  • Verify QSFP-DD or OSFP compatibility for 400G optics
