Product Overview｜S1000 Series

The NebulaMatrix S1000 Series SmartNIC is a fully domestic-chip-based 100GE intelligent network adapter developed for cloud computing, intelligent computing, and high-performance storage scenarios, delivering high-speed forwarding capabilities of up to 2x100G. Equipped with comprehensive hardware-accelerated forwarding and virtualization offload capabilities, the S1000 Series leverages its powerful hardware engine to significantly reduce system CPU utilization while substantially enhancing network performance. Moreover, the S1000 Series adopts a fully proprietary plug-and-play RoCEv2 solution that greatly improves ease of deployment in RDMA environments. On the security front, the S1000 Series supports secure boot, as well as IPSec and TLS offload based on AES and the national cryptographic SM4 algorithm, providing customers with advanced security protection measures.
