ConnectX-6 Lx 25/50G Ethernet SmartNIC
Smart, Accelerated Networking for Modern
Enterprise Data Centers.
NVIDIA® ConnectX®-6 Lx Ethernet smart network interface cards (SmartNIC)
deliver scalability, high performance, advanced security capabilities, and accelerated
networking with the best total cost of ownership for 25GbE deployments in cloud
and enterprise data centers. The SmartNICs support up to two ports of 25GbE,
or a single-port of 50GbE connectivity, along with PCI Express Gen3 and Gen4 x8
host connectivity to deliver cutting-edge performance and security for
uncompromising data centers.
SDN Acceleration
NVIDIA ASAP2 - Accelerated Switch and Packet Processing™ technology offloads
the software-defined networking (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 solution of choice. The ConnectX-6
Lx ASAP2 rich feature set accelerates public and on-premises enterprise clouds
and boosts communication service providers (CSP) transition to network function
virtualization (NFV). ASAP2 supports these communication service providers
by enabling packet encapsulations, such as MPLS and GTP, alongside cloud
encapsulations, such as VXLAN, GENEVE, and others.
Industry-leading RoCE
Following in the ConnectX tradition of providing industry-leading RDMA over
Converged Ethernet (RoCE) capabilities, ConnectX-6 Lx enables more scalable,
resilient, and easy-to-deploy RoCE solutions. With Zero-Touch RoCE (ZTR), the
ConnectX-6 Lx allows RoCE payloads to run seamlessly on existing networks
without special configuration, either to priority flow control (PFC) or explicit
congestion notification (ECN), for simplified RoCE deployments. ConnectX-6 Lx
ensures RoCE resilience and efficiency at scale.
Secure Your Infrastructure
In an era where data privacy is key, ConnectX-6 Lx adapters offer advanced, built-
in capabilities that bring security down to the endpoints with unprecedented
performance and scalability. ConnectX-6 Lx offers IPsec inline encryption and
decryption acceleration. ASAP2 connection-tracking hardware offload accelerates
Layer 4 firewall performance.
ConnectX-6 Lx also delivers supply chain protection with hardware root-of-trust
(RoT) for secure boot and firmware updates using RSA cryptography and cloning-
protection, via a device-unique key, to guarantee firmware authenticity.
