SP670 is a PCIe 4.0 x16 dual-port 100Gbps QSFP28 Ethernet network adapter based on Huawei HiSilicon Hi1822 chip. It provides an extended external service interface for the server.
SP670 supports MCTP (Management Component Transport Protocol) out-of-band management, which can achieve more efficient remote management and control in server management; Supports RDMA (RoCEv2), which does not require kernel intervention through the operating system, reduces data copying and CPU load; Supports GPU Direct, which allows data to bypass the CPU and directly transmit to the GPU, reducing CPU load and improving processing efficiency; supports DPDK, which can greatly improve data processing performance and throughput, and improve the work efficiency of data plane applications.
SP670 can be widely used in application scenarios such as AI/ML, high-performance computing, and cloud computing.
