Accelerate and Secure Cost-effectively


SDN Acceleration

NVIDIA Accelerated Switching and Packet Processing® technology offloads the SDN data plane to the SmartNIC, accelerating performance and offloading 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 ConnectX tradition of industry-leading RoCE capabilities, ConnectX-6 Lx enables more scalable, resilient, and easy-to-deploy RoCE solutions utilizing NVIDIA Zero Touch RoCE (ZTR). ConnectX-6 Lx allows RoCE payloads to run seamlessly on existing networks without requiring network configuration (no PFC, no ECN) for simplified RoCE deployments.


Secure Infrastructure

In an era where privacy of information is key and zero trust is the rule, ConnectX-6 Lx provides 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 firmware authenticity and unprecedented performance and scalability.
