NVIDIA ConnectX-6 InfiniBand Network Card (MCX653105A-ECAT)

1. Product Overview

The NVIDIA ConnectX-6 InfiniBand network card (model: MCX653105A-ECAT) is a high-performance dual-port 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, and cloud data centers.

2. Key Characteristics

• Up to 200Gb/s InfiniBand and Ethernet connectivity
• Hardware-based encryption with XTS-AES 256/512-bit
• Support for RDMA, RoCE, and NVMe over Fabrics
• Low-profile PCIe form factor with QSFP56 cages
• Compliant with InfiniBand Trade Association (IBTA) 1.3

3. Core Technologies

The ConnectX-6 leverages NVIDIA In-Network Computing, RDMA, and hardware offloads for TCP/IP, encryption, and virtualization. It supports PCIe Gen 4.0 and is compatible with major operating systems including Linux, Windows, and VMware.

4. Working Principle

The NIC card uses remote direct memory access (RDMA) to enable direct data transfer between servers and storage, bypassing the CPU. This reduces latency and increases throughput. In-Network Computing offloads further accelerate data processing within the network fabric.

5. Applications

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

6. Specifications

7. Advantages

• Higher bandwidth and lower latency than previous-generation network cards
• Hardware offloads reduce CPU overhead and improve efficiency
• FIPS-compliant encryption for secure data transmission
• Broad compatibility with leading server platforms and OSs

8. Service & Support

We offer 24/7 technical support, worldwide shipping, and a standard manufacturer warranty. Custom configuration and bulk order discounts are available.

9. Frequently Asked Questions
