Dual-port 100G QSFP28 PCIe 4.0 x16 network adapter based on Huawei HiSilicon Hi1822.
When AI training clusters and high-performance computing environments face bandwidth bottlenecks, low-latency connectivity becomes critical for maintaining throughput. The SP670 PCIe 4.0 x16 Dual-Port 100G Network Adapter addresses this by delivering massive bandwidth directly to the server bus, ensuring data-intensive applications run without interruption.
Powered by the Huawei HiSilicon Hi1822 chip, this adapter provides two QSFP28 ports supporting 100G/40Gbps link speeds over fiber. With support for RDMA (RoCEv2) and GPU Direct, it bypasses CPU intervention for data transfers, significantly reducing latency and CPU load. This enables efficient handling of large datasets in cloud computing and HPC scenarios, maximizing hardware utilization.
Ideal for AI/ML infrastructure and cloud data centers, the SP670 features MCTP for efficient out-of-band management and DPDK for accelerated packet processing. Its robust design includes full/half-height brackets and operates reliably between 5°C to 45°C, offering a scalable networking solution for modern enterprise servers.
