What is a SuperNIC, and how is it different from a traditional NIC?

A SuperNIC is a next-generation network accelerator designed for large-scale AI workloads. Unlike traditional NICs, it offers up to 800Gb/s bandwidth and supports RDMA and programmable Data Path Accelerator (DPA), enabling ultra-low latency communication between GPUs.

Questions & Answers

Ask a Question

Does the SuperNIC support port partitioning?

Yes. Each 400G port can be split into four 100G physical interfaces, supporting up to 8 port partitions for flexible configurations.

What makes the SuperNIC programmable?

It includes a Data Path Accelerator (DPA) with 16 hyper-threaded cores that can be programmed using NVIDIA’s DOCA SDK to implement congestion control, flow management, and custom logic.

Does the ConnectX-8 SuperNIC support virtualization?

Yes. It supports SR-IOV, VirtIO, and other virtualization technologies, making it ideal for multi-tenant and virtualized environments.
