NVIDIA ConnectX-6 InfiniBand Adapter Card (MCX653106A-HDAT)
Experience unprecedented data throughput and ultra-low latency with the NVIDIA ConnectX-6 InfiniBand Smart Network Interface Card (NIC). Engineered for high-performance computing (HPC), artificial intelligence (AI), and hyperscale data centers, this advanced network card delivers up to 200Gb/s per port, hardware-accelerated encryption, and sophisticated offload technologies to maximize efficiency and scalability while reducing CPU overhead.
Key Features
- Dual-port 200Gb/s InfiniBand and Ethernet connectivity
- Hardware offload for RoCE, NVMe over Fabrics, and T10-DIF
- Block-level XTS-AES 256/512 encryption with FIPS compliance
- Support for PCIe Gen 4.0 and NVIDIA Socket Direct technology
- Enhanced virtualization with SR-IOV and ASAP² acceleration
Core Technologies
The ConnectX-6 leverages cutting-edge technologies including Remote Direct Memory Access (RDMA), In-Network Computing, and hardware-based congestion control. It supports InfiniBand and Ethernet protocols, and features NVIDIA’s PeerDirect® and GPUDirect® technologies for accelerated GPU-to-GPU communication.
How It Works
The NIC card offloads network, storage, and security processing from the host CPU. Using dedicated engines for encapsulation, encryption, and packet pacing, it processes data at line rate with sub-nanosecond accuracy. The adapter uses PCIe lanes to interface with the host and supports both InfiniBand and Ethernet fabrics through OSFP or QSFP56 connectors.
Applications
- High-Performance Computing (HPC) clusters
- AI and Machine Learning training infrastructures
- Hyperscale cloud and enterprise data centers
- Storage area networks with NVMe over Fabrics
- Virtualized and NFV-enabled environments
