NVIDIA® ConnectX-5 InfiniBand/Ethernet Network Card - MCX653105A-HDAT

1. Product Overview

The NVIDIA ConnectX-5 VPI adapter card, model MCX653105A-HDAT, is a high-performance dual-port network card supporting both InfiniBand and Ethernet connectivity up to 100Gb/s per port. Designed for data centers, high-performance computing (HPC), and enterprise storage environments, this nic card offers advanced offload capabilities, low latency, and high message rates. It supports PCIe Gen4 and features hardware-based acceleration for NVMe over Fabrics, RDMA, and virtualization technologies.

2. Key Characteristics

• Dual-port 100Gb/s InfiniBand or Ethernet connectivity
• PCI Express 4.0 x16 host interface
• Hardware offload for RDMA, NVMe over Fabrics, and TCP/IP
• Support for Multi-Host and Socket Direct technologies
• Low-profile form factor with tail bracket design
• RoHS compliant and energy-efficient operation

3. Core Technologies

The ConnectX-5 leverages cutting-edge technologies including RDMA over Converged Ethernet (RoCE), NVMe over Fabrics offload, and hardware-based virtualization with SR-IOV. It complies with IEEE 802.3 standards for Ethernet and IBTA 1.3 for InfiniBand. The adapter also supports advanced features like adaptive routing, dynamic connected transport (DCT), and MPI tag matching offload.

4. Working Principle

The nic card operates by offloading network processing tasks from the CPU to the adapter’s dedicated hardware. Using RDMA, it enables direct memory access between systems without CPU involvement, reducing latency and improving throughput. The embedded PCIe switch allows efficient I/O consolidation, while hardware-based encryption and tunneling offloads enhance security and performance.

5. Applications

• High-Performance Computing (HPC) clusters
• Cloud and hyperscale data centers
• Enterprise storage and NVMe over Fabrics deployments
• Virtualized environments and software-defined networking (SDN)
• AI and machine learning infrastructure
