NVIDIA ConnectX SmartNICs

Designed to Address Modern Data Center Challenges

Performance and Versatility to Improve Data Center Efficiency and Scale

NVIDIA Mellanox ConnectX® SmartNICs utilize stateless offload engines, overlay networks, and native hardware support for RoCE and GPUDirect™ technologies to maximize application performance and data center efficiency. Developers can use ConnectX custom packet processing technologies to accelerate server-based networking functions and offload datapath processing for compute-intensive workloads including network virtualization, security, and storage functionalities.

Accelerate Packet Processing and Latency-Sensitive Workloads

Advanced accelerators and network offloads can be implemented on the ConnectX SmartNIC to free expensive CPU cycles for user application

ASAP2 Virtual Switching

NVIDIA Accelerated Switch and Packet Processing (ASAP2®) technology is designed to offload vSwitch/vRouter tasks by handling the dataplane processes in the NIC hardware. As a result, significantly higher performance is achievable without the associated CPU load.

Block-Level Encryption

The innovative security hardware engines of the ConnectX offload IPsec, TLS and offer IEEE AES-XTS inline encryption/decryption services to reduce latency and save on CPU utilization. This protection enables secure network connectivity in modern data-center environments.

Socket Direct™

The NVIDIA Socket Direct® technology enables direct PCIe access to multiple CPU sockets, eliminating network traffic having to traverse the inter-process bus and optimizing overall system performance.


GPUDirect® technology enables RDMA for all CPU/GPU pairs by ensuring that GPUs are linked to the CPUs closest to the adapter card. This provides a significant decrease in GPU-GPU communication latency and completely offloads the CPU from GPU-GPU communication.

Designing an Efficient Scale-Out Deep Learning Cloud

The basic challenge in Deep Learning is that just combining a whole bunch of compute nodes into a large cluster – and making them work together seamlessly – is not simple. In fact, if it is not done properly, the performance could become worse as you increase the number of GPUs, and the cost could become unattractive.
