Product Overview

The NVIDIA ConnectX-6 MCX653105A-ECAT is a high-performance dual-port smart network card (NIC) designed for next-generation data centers, high-performance computing (HPC), and artificial intelligence (AI) infrastructures. Supporting speeds of up to 200Gb/s per port over InfiniBand or Ethernet, this adapter delivers ultra-low latency, high message rates, and advanced hardware offloads. It is a key component of the NVIDIA Quantum InfiniBand platform, enabling efficient in-network computing and enhanced scalability for demanding workloads.

Key Selling Points:

• Dual-port 200Gb/s InfiniBand or Ethernet connectivity
• Hardware offloads for networking, storage, and security
• In-network computing acceleration for AI and HPC
• RoCE (RDMA over Converged Ethernet) support
• SR-IOV virtualization with up to 1K virtual functions

Characteristics

• Max bandwidth: 200Gb/s per port
• Low latency: Ultra-low response time for high-frequency trading and AI training
• High message rate: Up to 215 million messages per second
• Hardware encryption: XTS-AES 256/512-bit block-level encryption
• PCIe support: Gen 3.0 and 4.0
• Form factor: Low-profile PCIe stand-up card with QSFP56 cages
• RoHS and ODCC compliant

Technology

The ConnectX-6 leverages cutting-edge technologies including:

• InfiniBand Trade Association (IBTA) 1.3 compliance
• RDMA (Remote Direct Memory Access)
• NVMe over Fabrics (NVMe-oF) offload
• Hardware-based congestion control
• Tunneling offload for VXLAN, NVGRE, and Geneve
• IEEE AES-XTS encryption/decryption offload

Working Principle

The nic card operates by offloading network, storage, and security processing from the host CPU to the adapter’s dedicated hardware. Using RDMA, it enables direct memory access between servers or storage systems, reducing latency and CPU overhead. The in-network computing engine allows data processing within the network fabric, further optimizing performance for distributed applications.

Application / Usage

• High-Performance Computing (HPC) clusters
• AI and machine learning training environments
• Hyperscale cloud data centers
• Network Function Virtualization (NFV)
• Big data analytics and storage platforms
