HIGHLIGHTS

Providing up to two ports of 25GbE or a single-port of 50GbE connectivity, and PCIe Gen 3.0/4.0 x8 host connectivity, ConnectX-6 Lx is a member of Mellanox’s world-class, award-winning, ConnectX family of network adapters. Continuing Mellanox’s consistent innovation in networking, ConnectX-6 Lx provides

agility and efciency at every scale. ConnectX-6 Lx delivers cutting edge 25GbE performance and security

for uncompromising data centers.

Wide Selection of SmartNICs

ConnectX-6 Lx SmartNICs are available in several form factors including low-prole PCIe and OCP 3.0 cards with SFP28 connectors for 10/25GbE applications, or QSFP28 for 50GbE applications. Low-prole PCIe cards are available with tall and short brackets, while OCP3.0 cards are available with either a pull

tab or an internal lock bracket.

Best-in-Class SDN Acceleration

Mellanox’s ASAP2 - Accelerated Switch and Packet Processing® technology ofoads the SDN data plane

to the SmartNIC, accelerating performance and ofoading the CPU in virtualized or containerized cloud data centers. Customers can accelerate their data centers with an SR-IOV or VirtIO interface while continuing to enjoy their SDN of choice.

Industry-leading RoCE

Following the Mellanox ConnectX tradition of industry-leading RoCE capabilities, ConnectX-6 Lx enables more scalable, resilient, and easy-to-deploy RoCE solutions – Zero Touch RoCE. ConnectX-6 Lx allows

RoCE payloads to run seamlessly on existing networks without requiring network conguration (no PFC, no ECN) for simplied RoCE deployments. ConnectX-6 Lx ensures RoCE resiliency and efciency at scale.

Secure Your Infrastructure

In an era where privacy of information is key and zero trust is the rule, ConnectX-6 Lx adapters offer a

range of advanced built-in capabilities that bring infrastructure security down to every endpoint with unprecedented performance and scalability. ConnectX-6 Lx offers IPsec inline encryption/decryption acceleration. ASAP

ConnectX-6 Lx also delivers supply chain protection with hardware Root-of-Trust (RoT) for Secure Boot as

well as Secure Firmware Update using RSA cryptography and cloning-protection, via a device-unique key, to guarantee rmware authenticity.
