Overview

SP681 is a PCIe3.0 x8 dual-port 25Gbps SFP28 Ethernet network adapter based on Huawei HiSilicon Hi1822 chip. It provides an extended external service interface for the server.

SP681 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 Flow Director to achieve more accurate flow control and load balancing; supports DPDK, which can greatly improve data processing performance and throughput, and improve the work efficiency of data plane applications.

SP681 can be widely used in data centers, Internet cloud services, cloud computing and other application scenarios.
