Dual-port 100G QSFP28 NIC based on Huawei HiSilicon Hi1822 chip for AI and HPC.
LR-LINK presents the SP670, a cutting-edge PCIe 4.0 x16 dual-port 100G QSFP28 Ethernet network adapter engineered for the demanding needs of modern data centers. Built around the robust Huawei HiSilicon Hi1822 chipset, this adapter provides exceptional bandwidth and reliability, making it the perfect choice for AI/ML training clusters, high-performance computing (HPC), and large-scale cloud computing environments.
Optimized for performance and efficiency, the SP670 supports Remote Direct Memory Access (RDMA) over Converged Ethernet v2 (RoCEv2), allowing data to bypass the CPU and OS kernel for significantly reduced latency and CPU load. It also features GPU Direct technology, enabling direct data transfer between the network and GPU memory, which accelerates deep learning and scientific simulations. Additionally, full support for DPDK ensures that data plane applications achieve maximum throughput and processing speeds.
Beyond raw speed, the SP670 offers comprehensive management capabilities with MCTP (Management Component Transport Protocol) support for efficient out-of-band server control. It adheres to industry standards including IEEE 802.3ad (LACP), VXLAN, and SR-IOV, ensuring seamless integration into complex network infrastructures. With its flexible bracket options (Full/Half Height) and low power consumption profile, the SP670 delivers enterprise-grade networking solutions tailored for next-generation infrastructure.
