ConnectX-6 Dx EN adapter card, 100GbE, Single-port QSFP56, PCIe 4.0 x16, No Crypto, Tall Bracket
作为世界上最先进的云智能网卡，ConnectX-6 Dx 提供多达两个 25、50 或 100Gb/s 的端口或一个 200Gb/s 的单端口以太网连接，采用 50Gb/s PAM4 SerDes 技术和 PCIe Gen 4.0 主机连接。
ConnectX-6 Dx 继续在 NVIDIA 在可扩展云结构方面的创新路径中，在各种规模上提供无与伦比的性能和效率。ConnectX-6 Dx 的创新硬件卸载引擎（包括 IPsec 和 TLS 内联动态数据加密）非常适合在现代数据中心环境中实现安全网络连接。
NVIDIA® ConnectX®-6 Dx is a highly secure and advanced smart network interface card (SmartNIC) that accelerates mission-critical cloud and data center applications, including security, virtualization, SDN/NFV, big data, machine learning, and storage. ConnectX-6 Dx provides up to two ports of 100Gb/s or a single port of 200Gb/s Ethernet connectivity and is powered by 50Gb/s (PAM4) or 25/10 Gb/s (NRZ) SerDes technology.
ConnectX-6 Dx features virtual switch (vSwitch) and virtual router (vRouter) hardware accelerations delivering orders-of-magnitude higher performance than softwarebased solutions. ConnectX-6 Dx supports a choice of single-root I/O virtualization (SR-IOV) and VirtIO in hardware, enabling customers to best address their application needs. By offloading cloud networking workloads, ConnectX-6 Dx frees up CPU cores for business applications while reducing total cost-of-ownership.
In an era where data privacy is key, ConnectX-6 Dx provides built-in inline encryption/ decryption, stateful packet filtering, and other capabilities, bringing advanced security down to every node with unprecedented performance and scalability.
Built on the solid foundation of NVIDIA’s ConnectX line of SmartNICs, ConnectX-6 Dx offers best-in-class RDMA over Converged Ethernet (RoCE) capabilities, enabling scalable, resilient, and easy-to-deploy RoCE solutions. For data storage, ConnectX-6 Dx optimizes a suite of storage accelerations, bringing NVMe-oF target and initiator offloads.
