MCX653105A-HDAT Product Overview

The NVIDIA ConnectX-6 MCX653105A-HDAT is a high-performance dual-port network card supporting 200Gb/s InfiniBand and Ethernet connectivity. Designed for data-intensive environments, this nic card leverages in-network computing and hardware offloads to maximize throughput, reduce latency, and free up host CPU resources. Ideal for HPC, AI, machine learning, and cloud data centers, the ConnectX-6 series sets a new standard in smart networking.

MCX653105A-HDAT Key Features

• Dual-port 200Gb/s InfiniBand or Ethernet connectivity
• Hardware offloads for RDMA, NVMe over Fabrics, and encryption
• In-network computing acceleration
• Low latency and high message rate (up to 215 million messages/sec)
• Block-level AES-XTS encryption with FIPS compliance
• Support for PCIe Gen 4.0 and Gen 3.0
• NVIDIA Socket Direct technology for multi-socket servers

MCX653105A-HDAT Core Technologies

The ConnectX-6 leverages cutting-edge technologies including RDMA over Converged Ethernet (RoCE), InfiniBand Verbs, SR-IOV, NVMe-of offload, and hardware-based encryption. It supports advanced protocols like VXLAN, Geneve, and NVGRE overlay networks, and is compliant with IEEE Ethernet standards and IBTA specifications.

MCX653105A-HDAT How It Works

The nic card offloads network, storage, and security processing from the host CPU. Using embedded processors, it handles packet processing, encryption, and RDMA operations directly on the adapter. This reduces latency, increases bandwidth, and improves overall system efficiency. The network card also supports adaptive routing and end-to-end flow control for optimized data paths.

Applications

• High-Performance Computing (HPC) clusters
• Artificial Intelligence and Machine Learning training
• Hyperscale cloud data centers
• Big Data analytics and storage networks
• Virtualized and NFV environments

Specifications

Advantages

• Superior throughput and lower latency compared to previous-generation nic card solutions
• Hardware offloads reduce CPU overhead and improve scalability
• Enhanced security with inline encryption and FIPS compliance
• Flexible deployment in both InfiniBand and Ethernet environments
• Robust driver support for Linux, Windows, VMware, and more
