NVIDIA CONNECTX INFINBAND 适配器产品组合
智能、高效、可扩展
复杂的工作负载需要对高分辨率模拟、超大数据集和高度并行化算法进行超快速处理。随着这些计算需求的不断增长，NVIDIA® Quantum InfiniBand 平台是完全可卸载的网络内计算加速技术，提供了在高性能计算 (HPC)、人工智能和超大规模方面实现无与伦比的性能所需的性能飞跃成本和复杂性更低的云基础架构。
NVIDIA ConnectX® 智能主机通道适配器 (HCA) 具有一流的性能和效率，是需要高带宽、高消息速率和低延迟以实现高服务器效率和应用程序生产力的 HPC 集群的理想解决方案。通过远程直接内存访问 (RDMA) 流量整合和虚拟化硬件加速，ConnectX 提供更佳 I/O 服务，以实现数据中心、大规模存储系统和云计算的更大投资回报 (ROI)。
