Use Case Applications

Networking HPC

High-Performance Computing (HPC)

ConnectX-6 delivers the highest throughput and message rate in the industry and is the perfect product to lead HPC data centers toward exascale levels of performance and scalability.

ConnectX-6 offers enhancements to HPC infrastructures by providing MPI acceleration and offloading, as well as support for network atomic and PCIe atomic operations.

Machine Learning and AI

Machine Learning and AI

Machine learning relies on high throughput and low latency to train deep neural networks and to improve recognition and classification accuracy. As the first adapter card to deliver 200Gb/s throughput supporting NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) , ConnectX-6 and Quantum switches provide machine learning applications with the performance and scalability they need.

Networking Storage

Storage

NVMe storage devices are gaining momentum by offering exceptionally fast remote direct-memory access (RDMA) to storage media. With its NVMe over Fabrics (NVMe-oF) target and initiator offloads, ConnectX-6 brings further optimizations to NVMe-oF, enhancing CPU utilization and scalability.
