The Stargate-C3000 SmartNIC chip provides up to two 100Gb/s Ethernet ports, or four 25Gb/s Ethernet ports, andone PCIe Gen4x16 or PCIe Gen4x8 host interfaces, and offers comprehensive feature set and functionalities

Target Application

  • P4-Programmable Network Acceleration
    • Enables user-defined data plane packet processing policies, including packet parsing, matching, forwarding, and modification, offering flexible support for proprietary protocols or customized service.
    • Supports flow table management via RTE Flow or TC Flower APIs, delivering efficient flow entry installation, querying, and updating mechanisms
  • High-Performance RDMA Engine
    • Equipped with an industry-leading RDMA engine with standard Verbs programming interfaces, providing users high- speed, ultra-low latency, low CPU overhead, and scalable service capabilities through the flexible RoCEv2 high- performance networking.
    • Integrates with NCCL and OpenMPI collective communication libraries, enhancing GPU cluster performance through GPU Direct RDMA and GPU Direct Storage technologies.
    • Accelerates storage services such as iSER, NFS RDMA, SMB, and NVMe-oF
  • High-Performance Shared Storage
    • Supports NVMe-oF acceleration for high performance storage application. RDMA engine processes packet encapsulation, decapsulation and storage data transmission, providing a high-throughput, low-latency, and highly reliable storage solution while significantly reducing host CPU utilization
  • Cloud-Native Virtualization Support
    • Supports SR-IOV (Single Root I/O Virtualization), delivering
      thousands of Virtio Functions to adapt to virtualization and
      containerized application scenarios.
    • Leverages cloud-native Virtio drivers, simplifying development
      by eliminating the needs for proprietary driver installation.
    • Supports live migration to meet the high-reliability demands of
      cloud computing scenarios.
  • Security Features
    • Configurable network packet filtering to meet the
      increasingly stringent security requirements.
    • Guarantees firmware upgrade security through a Root
      of Trust mechanism
  • Management and Deployment
    • Facilitates remote data center deployment via PXE/iPXE
      technologies over IPv4/IPv6 networks.
    • Provides management control capabilities such as MCTP
      over SMBus/PCIe, PLDM, and NC-SI, enabling efficient
      server-side NIC monitoring and management
  • Comprehensive Software SDK
    • Comprehensive Resnics Software Development Kit
      (RDK) to facilitate the chip and SmartNIC adoption.
      Seamless integration with mainstream cloud-native
      software (e.g., DPDK, SPDK, vDPA, RTE Flow, TC
    • Flower, Ethtool), accelerating user deployment cycles
      and Time to Market
