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.
- Supports SR-IOV (Single Root I/O Virtualization), delivering
- Security Features
- Configurable network packet filtering to meet the
increasingly stringent security requirements. - Guarantees firmware upgrade security through a Root
of Trust mechanism
- Configurable network packet filtering to meet the
- 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
- Facilitates remote data center deployment via PXE/iPXE
- 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
- Comprehensive Resnics Software Development Kit
