SmartNIC Portfolio

• 10/25 Gb/s Ethernet

• Various form factors:

- PCIe low-profile

- OCP 3.0 Small Form Factor (SFF)

• Connectivity options:

- SFP28

• PCIe Gen 3.0/4.0 x8

• Crypto and non-crypto versions

SDN Acceleration

NVIDIA ASAP2 - Accelerated Switch and Packet ProcessingTM 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.
