Questions fréquemment posées
The NVIDIA ConnectX-6 DX is a high-performance SmartNIC (Smart Network Interface Card) that provides up to two ports of 100Gb/s or a single-port of 200Gb/s Ethernet connectivity. Its key features include advanced security capabilities like Crypto-IPsec and TLS encryption, hardware-based L4 firewall, virtualization support through ASAP2 technology, and Zero Touch RoCE for simplified deployments. The card utilizes PCI Express 4.0 x16 interface and supports optical fiber connectivity with QSFP56 expansion slots.
The ConnectX-6 DX provides comprehensive security features including: Crypto-IPsec and TLS data-in-motion encryption/decryption offload, AES-XTS block-level data-at-rest encryption, hardware-based L4 firewall with DoS attack protection, hardware root-of-trust (RoT) secure boot, secure firmware updates using RSA cryptography, and cloning protection through device-unique secret keys. These features ensure endpoint security with high performance and scalability.
The ConnectX-6 DX features two QSFP56 ports supporting 100GBase-X network technology over optical fiber. It utilizes a PCI Express 4.0 x16 host interface for maximum throughput. The card can deliver either dual-port 100Gb/s or single-port 200Gb/s Ethernet connectivity, powered by advanced 50Gb/s (PAM4) and 25/10 Gb/s (NRZ) SerDes technology.
The ConnectX-6 DX supports advanced virtualization through ASAP2 (Accelerated Switch and Packet Processing) technology, which provides virtual switch (vSwitch) and virtual router (vRouter) hardware offloads. It supports both SR-IOV and VirtIO in-hardware offload capabilities and can handle up to 8 million rules. The card also includes advanced QoS features with traffic shaping and classification-based data policing.
Zero Touch RoCE (ZTR) is a feature that simplifies RoCE (RDMA over Converged Ethernet) deployments by allowing RoCE payloads to run seamlessly on existing networks without requiring special configuration for priority flow control (PFC) or explicit congestion notification (ECN). This makes deployment easier and ensures better resilience, efficiency, and scalability in network operations.
The ConnectX-6 DX comes in a plug-in card form factor with an OCP 3.0 bracket height. It's designed for server integration and features QSFP56 expansion slots for optical fiber connectivity. The card utilizes a PCI Express 4.0 x16 interface for maximum bandwidth and performance.
The ConnectX-6 DX is designed for mission-critical data center applications including security, virtualization, SDN/NFV, big data, machine learning, and storage. It's particularly suited for virtualized cloud data centers requiring high security, advanced networking capabilities, and high-performance RoCE implementations. The card's features make it ideal for environments needing robust security, high bandwidth, and efficient virtualization support.
The ConnectX-6 DX features programmable congestion control with an API for building user-defined congestion control algorithms. This allows for customized solutions in various environments where RoCE and background TCP/IP traffic run concurrently. The card's advanced QoS capabilities include traffic shaping and classification-based data policing for optimal network performance.
