NVIDIA ConnectX-6 InfiniBand Adapter MCX653105A-EFAT
Product Overview
The NVIDIA ConnectX-6 InfiniBand adapter, model MCX653105A-EFAT, is a high-performance dual-port network card 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 infrastructures. This InfiniBand adapter supports both InfiniBand and Ethernet protocols, providing flexibility and scalability for modern data centers.
Key Features
- Up to 200Gb/s per port bandwidth
- Ultra-low latency and high message rate
- Hardware offloads for RDMA, NVMe over Fabrics, and encryption
- Support for InfiniBand and Ethernet protocols
- RoCE (RDMA over Converged Ethernet) support
- PCIe Gen 3.0/4.0 compatibility
Core Technologies
The ConnectX-6 leverages cutting-edge technologies including In-Network Computing, RDMA, and hardware-based encryption. It complies with IBTA 1.3 standards and supports PCIe Atomic Operations, T10-DIF, and NVMe over Fabrics offloads. The adapter also features NVIDIA Socket Direct technology for optimized multi-socket server performance.
How It Works
The NIC card uses remote direct memory access (RDMA) to enable direct data transfer between servers and storage, bypassing the CPU to reduce latency and free up processing resources. It also offloads encryption, tunneling, and storage protocols directly in hardware, improving efficiency and scalability.
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
