Industry's most secure and advanced cloud network interface cards (NIC), accelerating mission-critical data-center applications, such as security, virtualization, SDN/NFV, big data, machine learning, and storage, and delivering the highest return on investment (ROI)
Providing up to two ports of 100Gb/s or single-port of 200Gb/s Ethernet connectivity, ConnectX-6 Dx is a member of Mellanox's world-class, award-winning ConnectX series of network adapters. Powered by leading 50Gb/s (PAM4) and 25/10 Gb/s (NRZ) SerDes technology and novel capabilities that accelerate cloud and data-center payloads.
Security From Zero Trust to Hero Trust
In an era where privacy of information is key and zero trust is the rule, ConnectX-6 Dx adapters offer a range of advanced built-in capabilities that bring security down to the end-points with unprecedented performance and scalability, including:
Crypto - IPsec and TLS data-in-motion inline encryption and decryption offload, and AES-XTS block-level data-at-rest encryption and decryption offload.
Probes & DoS Attacks Protection - ConnectX-6 Dx enables a hardware-based L4 firewall by ASAP offloading of stateful connection tracking.
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 Virtualization
ConnectX-6 Dx delivers another level of innovation to enable building highly efficient virtualized cloud data centers:
Virtualization - Mellanox ASAP2 - Accelerated Switch and Packet Processing® technology for vSwitch/vRouter hardware offload, delivers orders of magnitude higher performance vs. 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 - Includes traffic shaping, and classification-based data policing.
Industry-leading RoCE
Following the Mellanox ConnectX tradition of industry-leading RoCE capabilities, ConnectX-6 Dx adds another layer of innovation to enable more scalable, resilient and easy-to-deploy RoCE solutions.
Zero Touch RoCE - Simplifying RoCE deployments ConnectX-6 Dx allows RoCE payloads to run seamlessly on existing networks without requiring special configuration on the network (no PFC, no ECN). ConnectX-6 Dx's new features ensure resiliency and efficiency at scale of such deployments.
Configurable Congestion Control - API to build user-defined congestion control algorithms, best serving various environments and RoCE and TCP/IP traffic patterns.
Efficient Storage Solutions
With its NVMe-oF target and initiator offloads, ConnectX-6 Dx brings further optimization to NVMe-oF, enhancing CPU utilization and scalability. Additionally, ConnectX-6 Dx supports hardware offload for ingress/egress of T10-DIF/PI/CRC32/CRC64 signatures, as well as AES-XTS encryption/decryption offload enabling user-based key management and a one-time-FIPS-certification approach.
Wide Selection of NICs
ConnectX-6 Dx NICs are available in several form factors including low-profile PCIe, OCP2.0 and OCP3.0 cards, with various network connection types (SFP28/56, QSFP28/56, or SFP-DD). The ConnectX-6 Dx portfolio also provides options for Mellanox Multi-Host® and Mellanox Socket Direct® configurations.
