NVIDIA ConnectX-6 Single-Port 200GbE HDR100 InfiniBand Adapter

The NVIDIA ConnectX-6 Single-Port 200GbE HDR100 InfiniBand Adapter is a high-performance network interface card engineered for exascale computing environments. Built on the fifth-generation InfiniBand architecture, the adapter delivers 200 Gigabits per second aggregate throughput with HDR100 protocol support, enabling ultra-low latency inter-node communication critical for tightly-coupled distributed workloads.

This single-port design integrates advanced features including In-Network Computing (INC) capabilities for on-switch algorithmic acceleration, SHARP (Scalable Hierarchical Aggregation and Reduction Protocol) for collective operation optimization, and full support for GPUDirect RDMA, enabling direct data transfers between GPUs and remote memory without CPU intervention. The adapter supports both InfiniBand and RoCE v2 protocols simultaneously across a single physical port.

Widely deployed in HPC clusters, AI training infrastructures, and enterprise data centers requiring sub-microsecond latency and lossless Ethernet semantics, the ConnectX-6 HDR100 has become the standard interconnect for GPU-accelerated supercomputing installations and large-scale machine learning training platforms.

Ideal for

• High-performance computing (HPC) clusters running tightly-coupled scientific simulations requiring sub-microsecond MPI collective operations
• AI and deep learning training environments with distributed GPU farms requiring low-latency NCCL and parameter server synchronization
• Financial services high-frequency trading and risk analytics platforms leveraging ultra-low latency interconnects
• Exascale research computing facilities and national laboratories consolidating petabyte-scale data analytics workloads
• Enterprise machine learning platforms supporting multi-node distributed training across GPU clusters
• Cloud service provider fabric upgrades for GPU-as-a-service infrastructure serving AI workload tenants
