II. Core Product Advantages
1. Domesticized IT innovation underlying architecture
Equipped with the domestically produced Huawei Kunpeng 920 processor (with optional 920S/920L dual modules), it is compatible with the domestic autonomous computing platform;
Natively supports three domestic operating systems: open-source Euler Kunpeng Edition, Kylin Kunpeng Edition, and HarmonyOS, meeting the requirements for domestic innovation and substitution;
Optional TCM security chip enhances data and system security at the hardware level, meeting the requirements of security classification protection and confidential scenarios;
The 920S features onboard memory, while the 920L supports standard DDR4 memory modules, which can be customized to meet domestic chip control requirements as needed.
2. Exceptional network communication capabilities
Equipped with 4 onboard 10 Gigabit SFP+ optical ports and 2 Gigabit RJ45 electrical ports, it supports both high-speed fiber optic transmission and conventional Ethernet connections, ideal for high-bandwidth applications such as big data collection, industrial private networks, video aggregation, and edge gateways. Featuring an independent Gigabit BMC management port, the service network and management network are physically isolated, ensuring that operations and maintenance do not consume service bandwidth.
3. Flexible High-Performance PCIe 4.0 Expansion
Kunpeng 920S Module: All 3 PCIe 4.0 slots (X16×1 + X8×2) are fully available;
Kunpeng 920L Module: 2 PCIe 4.0 slots (X16×1 + X8×1);
Expandable peripherals such as acquisition cards, graphics cards, RAID cards, U.2 hard disk cards, and acceleration cards; when only NVMe U.2 hard drives are connected, they occupy the X16 slot, offering strong expansion compatibility.

4. Multimode High-Capacity Storage Solution
1 lane M.2 2280 PCIe 4.0 high-speed solid-state drive (system disk high-speed read/write);
4 x 2.5-inch SATA/SAS hard drive bays, compatible with RAID cards for disk array configuration, supporting U.2 high-speed hard drive expansion to balance system high-speed storage and massive business data retention.
5. Professional Server-Level Remote Operations and Maintenance
Equipped with Huawei Hi1711 BMC management module, it fully supports IPMI, KVM remote desktop, and virtual media mounting. Combined with a rear-mounted independent management port, it enables remote power on/off, system reinstallation, and fault troubleshooting when the device crashes or the system fails, significantly reducing unattended data center operation and maintenance costs.
6. Industrial-grade stable hardware design
Power Supply: CRPS redundant power supply, standard 550W, optional 800W, with no service interruption in case of single power supply failure;
Temperature and humidity: Operating temperature 5°C~35°C, storage -40°C~65°C, stable operation in non-condensing environments, suitable for data centers and lightly industrialized machine rooms;
Rich I/O: VGA display, COM serial port, 4-channel USB 3.0, compatible with traditional industrial peripherals, monitors, and debugging devices;
Standard 4U rack-mounted chassis, compatible with 19-inch universal cabinets, ensuring easy deployment and replacement.
