NVIDIA ConnectX-6 DX

ETHERNET SMARTNIC

NVIDIA® ConnectX®-6 Dx is a highly secure and advanced smart network interface card (SmartNIC) to accelerate mission-critical data center applications, such as security, virtualization, SDN/NFV, big data, machine learning, and storage. It provides up to two ports of 100Gb/s or a single-port of 200Gb/s Ethernet connectivity and the highest ROI of any SmartNIC.

ConnectX-6 Dx is powered by leading 50Gb/s (PAM4) and 25/10 Gb/s (NRZ) SerDes technology and novel capabilities that accelerate cloud and data center payloads.

Zero-Trust Security

In an era where data privacy is key, ConnectX-6 Dx adapters offer advanced, built-in capabilities that bring security down to the endpoints with unprecedented performance and scalability:

• Crypto—IPsec and TLS data-in-motion inline encryption and decryption offload, and AES-XTS block-level, data-at-rest encryption and decryption offloads

• Probes and denial-of-service (DoS) attack protection—ConnectX-6 Dx enables a hardware-based L4 firewall by offloading stateful connection tracking through NVIDIA ASAP2 - Accelerated Switch and Packet Processing® offload technology

• NIC security—Hardware root-of-trust (RoT) secure boot and secure firmware update using RSA cryptography, and cloning protection, via a device-unique secret key

Advanced Vistualization

ConnectX-6 Dx enables building highly efficient virtualized cloud data centers:

• Virtualization—ASAP2 delivers virtual switch (vSwitch) and virtual router (vRouter) hardware offloads at orders-of-magnitude higher performance than software-based solutions. ConnectX-6 Dx ASAP2 offers both SR-IOV and VirtIO in-hardware offload capabilities and supports up to 8 million rules.

• Advanced quality of service (QoS)—ConnectX-6 Dx includes traffic shaping and classification-based data policing

Industry-Leading RoCE

With industry-leading capabilities, ConnectX-6 Dx delivers more scalable, resilient, and easy-to-deploy remote direct-memory access over converged Ethernet (RoCE) solutions.

• Zero Touch RoCE (ZTR)—Simplifying RoCE deployments, ConnectX-6 Dx with ZTR allows RoCE payloads to run seamlessly on existing networks without special configuration, either to priority flow control (PFC) or explicit congestion notification (ECN). ConnectX-6 Dx ensures the resilience, efficiency, and scalability of deployments.

• Programmable congestion control—ConnectX-6 Dx includes an API for building userdefined congestion control algorithms for various environments running RoCE and background TCP/IP traffic concurrently.

Best-In-Class PTP For Time Sensitive Application

NVIDIA offers a full IEEE 1588v2 Precision Time Protocol (PTP) software solution as well as time-sensitive-related features called 5T for 5G. NVIDIA PTP and 5T for 5G software solutions are designed to meet the most demanding PTP profiles. ConnectX-6 Dx incorporates an integrated PTP hardware clock (PHC) that allows the device to achieve sub-20 nanosecond (nsec) accuracy while offering timing-related functions, including timetriggered scheduling or time-based, software-defined networking (SDN) accelerations (time based ASAP²). 5T for 5G technology also enables software applications to transmit front-haul radio area network (RAN)-compatible data in high bandwidth. The PTP solution supports slave clock, master clock, and boundary clock operations.

ConnectX-6 Dx also supports SyncE, allowing selected ConnectX-6 Dx SmartNICs to provide PPS-Out or PPS-In signals from designated SMA connectors.

Efficient Storage Solutions

With its NVMe-oF target and initiator offloads, ConnectX-6 Dx brings further optimization, enhancing CPU utilization and scalability. Additionally, ConnectX-6 Dx supports hardware offload for ingress and egress of T10-DIF/PI/CRC32/CRC64 signatures and AES-XTS encryption and decryption offloads, enabling user-based key management and a one-time Federal Information Processing Standards (FIPS) certification approach.

NIC Portfolio

ConnectX-6 Dx SmartNICs are available in several form factors including low-profile PCIe, OCP2.0 and OCP3.0 cards, with various network connector types (SFP28/56, QSFP28/56, or DSFP). The ConnectX-6 Dx portfolio also provides options for NVIDIA Multi-Host® and NVIDIA Socket Direct® configurations.

ConnectX-6 Dx adds significant improvements to NVIDIA Multi-Host applications by offering advanced QoS features that ensure complete isolation among the multiple hosts connected to the NIC, and by achieving superior fairness among the hosts.
