NVIDIA ConnectX-6 InfiniBand Adapter MCX653106A-ECAT

200Gb/s Dual-Port Smart Adapter with In-Network Computing

The NVIDIA ConnectX-6 MCX653106A-ECAT delivers up to 200Gb/s bandwidth, sub-microsecond latency, and hardware offloads for HPC, AI, and hyperconverged storage. Featuring RDMA, NVMe-oF acceleration, block-level XTS-AES encryption, and PCIe 4.0, this dual-port QSFP56 InfiniBand adapter maximizes data center efficiency and scalability. Ideal for GPU clusters, ML training, and mission-critical networks.

InfiniBand & Ethernet support RDMA / GPUDirect NVMe-oF offload
Product Overview

The MCX653106A-ECAT is part of the NVIDIA ConnectX-6 InfiniBand adapter family, engineered for the most demanding workloads. It combines two QSFP56 ports capable of 200Gb/s InfiniBand or 200Gb/s Ethernet connectivity, offering hardware-based reliable transport, congestion control, and In-Network Computing engines. By offloading collective operations, MPI tag matching, and encryption from the host CPU, the adapter reduces CPU overhead and increases application performance in large-scale clusters. Enterprises, research labs, and hyperscale data centers rely on ConnectX-6 to build energy-efficient, low-latency fabrics.

Advanced Technology

Built on NVIDIA's proven InfiniBand architecture, ConnectX-6 integrates In-Network Computing to accelerate MPI operations, deep learning frameworks, and storage protocols. The adapter supports Remote Direct Memory Access (RDMA) for zero-copy data transfers, bypassing the CPU and kernel. Hardware-based congestion control ensures predictable performance even under heavy load. Additionally, NVIDIA GPUDirect RDMA allows direct data exchange between GPU memory and the network adapter, slashing latency for AI training. With support for NVMe over Fabrics (NVMe-oF) offloads, the card reduces CPU utilization in storage arrays while enabling high-throughput, low-latency access to NVMe flash.

Typical Deployments
  • High Performance Computing (HPC): Large-scale simulations, weather modeling, and computational fluid dynamics requiring low latency and high bandwidth.
  • AI & Machine Learning Clusters: Distributed training of deep neural networks, leveraging GPUDirect and RDMA for maximum efficiency.
  • NVMe-oF Storage Systems: Target or initiator offloads enable high-performance disaggregated storage with low CPU overhead.
  • Hyperscale Data Centers: Virtualized environments with SR-IOV, overlay networks, and service chaining.
  • Financial Services: Ultra-low latency trading infrastructure requiring deterministic performance.
Compatibility

The ConnectX-6 MCX653106A-ECAT is compatible with a wide range of servers, switches, and operating systems. It interoperates with NVIDIA Quantum InfiniBand switches (HDR 200Gb/s), as well as 200GbE Ethernet switches. The adapter supports standard PCIe slots (x16, x8, x4) and includes driver support for major OS platforms.

Q: Can I use this card in a PCIe 3.0 slot?
A: Yes, it is backward compatible with PCIe 3.0. However, maximum bandwidth may be limited compared to PCIe 4.0.
Q: Does the adapter include NVMe-oF hardware offload?
A: Yes, ConnectX-6 provides full NVMe-oF target and initiator offloads, significantly reducing CPU overhead for storage workloads.
Important Precautions
• Ensure server motherboard has sufficient airflow for high-speed adapters. Use passive or active QSFP56 cables within recommended temperature ranges.
• Confirm the PCIe slot provides adequate power (up to 75W via slot; this adapter typically uses <25W).
• For liquid-cooled platforms, check compatibility with Intel Server System D50TNP if cold plate variant is needed (this OPN is standard air-cooled).
• Verify OS driver compatibility with latest OFED or WinOF-2 stacks.
