NVIDIA ConnectX-6 InfiniBand Adapter Card MCX653105A-EFAT

1. Product Overview

The NVIDIA ConnectX-6 MCX653105A-EFAT is a high-performance dual-port InfiniBand and Ethernet smart network adapter designed for data-intensive environments. It delivers up to 200Gb/s per port with ultra-low latency and advanced offload capabilities, making it ideal for HPC, AI, machine learning, and cloud data centers. This network card supports both InfiniBand and Ethernet protocols, providing flexibility and scalability for modern data infrastructure.

2. Key Characteristics

• Dual-port 200Gb/s InfiniBand and Ethernet connectivity
• Hardware offload for RDMA, NVMe over Fabrics, and encryption
• Support for PCIe Gen 4.0 and 3.0
• Low-profile PCIe form factor with QSFP56 cages
• In-Network Computing acceleration
• Block-level AES-XTS encryption with FIPS compliance
• Enhanced virtualization with SR-IOV and ASAP² technology

3. Core Technologies

The ConnectX-6 NIC card leverages cutting-edge technologies including RDMA over Converged Ethernet (RoCE), InfiniBand Transport, NVIDIA GPUDirect®, and hardware-accelerated encryption. It complies with IEEE 802.3, IBTA 1.3, and PCIe 4.0 standards, ensuring broad interoperability and high performance.

4. Working Principle

The ConnectX-6 adapter uses remote direct memory access (RDMA) to enable direct data transfer between server memory and the network, bypassing the CPU. This reduces latency and CPU overhead. With built-in processing engines, it offloads tasks such as encryption, packet pacing, and collective operations directly into the network fabric.

5. Applications

This network card is widely used in:

• High-Performance Computing (HPC) clusters
• Artificial Intelligence and Deep Learning training
• Hyper-scale cloud data centers
• Storage area networks (SAN) with NVMe over Fabrics
• Virtualized and software-defined data centers
