Stargate-N2025 DPU
SmartNIC
Overview
Stargate-N2025 is a P4 programmable DPU with independent intellectual property rights. It includes 2x 25G Ethernet ports, 2x 1000BASE-T GE management Ethernet port.
The P4 network acceleration engine is a VLIW ISA P4 processor designed for vSwitch acceleration, with specific P4 instructions to complete protocol parsing, packet encapsulation and decapsulation. And it supports tens of millions of flow tables forwarding while guaranteeing the wire-speed forwarding performance.
Features
Stargate-N2025 DPU features high-performance, low-latency and high-flexibility. The dynamically programmable P4 engine empowers users to flexibly extend or customize new protocols in the P4 language based on specific application requirements. At the same time, when updating or upgrading P4 applications, the business flow can be uninterrupted.
Thus, Stargate-N2025 can be used in different application scenarios in different fields, and is the competitive network application acceleration solution for OVS, RDMA, Storage acceleration, Bare metal, Virtualization etc.
