NVIDIA ConnectX-6 MCX653106A-HDAT 200Gb/s InfiniBand Smart NIC Card
The NVIDIA ConnectX-6 MCX653106A-HDAT is a high-performance dual-port network card supporting 200Gb/s InfiniBand and Ethernet connectivity. Designed for data-intensive environments, this nic card features hardware offloads, in-network computing, and advanced security, making it ideal for HPC, AI, and cloud infrastructures.
Key Features
- Dual-port 200Gb/s InfiniBand/Ethernet connectivity
- Hardware offloads for RDMA, NVMe-oF, and encryption
- In-Network Computing acceleration
- Low latency and high message rate (215M msg/s)
- Block-level AES-XTS encryption with FIPS compliance
Technology
The ConnectX-6 leverages InfiniBand Architecture Specification 1.3, RoCE (RDMA over Converged Ethernet), PCIe Gen 4.0, and hardware-based offloads for networking, storage, and security. It supports SR-IOV, overlay networks (VXLAN, Geneve), and advanced virtualization.
How It Works
The nic card uses remote direct memory access (RDMA) to enable direct data movement between servers and storage, bypassing the CPU. Its in-network computing engines offload collective operations and encryption, reducing host overhead and improving efficiency.
Applications
- High-Performance Computing (HPC) clusters
- AI and machine learning training networks
- Cloud data centers and hyperscale environments
- Storage area networks (NVMe-oF, iSER, SMB Direct)
- Virtualized and NFV infrastructure
