Abstract

In response to the demand for domestic substitution in IT innovation transformation projects across the financial sector, state-owned enterprises, and Party and government institutions, Zhongxin Chuang… DNTS-9HG The domestically developed time server is equipped with Hygon and Phytium domestic processors, featuring full-stack domestic software and hardware adaptation. It is compatible with the Kylin and UOS operating systems, supports a single‑Beidou dual‑mode time‑synchronization mode, and delivers nanosecond‑level synchronization accuracy. The device is fully integrated. NTP/PTP Dual‑protocol output, coupled with a hardware‑redundant architecture that ensures highly reliable operation, and supported by compatible monitoring and management tools tailored for the indigenous information technology ecosystem, it seamlessly aligns with the time‑series synchronization requirements of indigenous data centers and domestic server clusters, having passed the software–hardware compatibility certification of the Indigenous Information Technology Industry Alliance.

I. Industry Background and Timing Challenges

The indigenous innovation (XinChuang) renovation project mandates the complete replacement of all data center infrastructure—both hardware and software—with domestically produced products, including conventional imported time servers, x86 Foreign‑made infrastructure equipment cannot pass domestic localization acceptance testing. Domestic server clusters, databases, and middleware lack compatible domestically produced time‑synchronization devices, resulting in issues such as poor protocol compatibility, degraded synchronization accuracy, and non‑interoperable management platforms. Moreover, most indigenous innovation (XinChuang) projects impose stringent requirements for device security, log auditing, and tiered access control, which conventional time‑synchronization devices are unable to meet.

II. DNTS-9HG Introduction to the Core of Indigenous Innovation Servers

DNTS-9HG A standardized time‑synchronization server developed by Zhongxin Chuangzhuan specifically for indigenous information‑technology (IT) innovation scenarios, featuring hardware options with either Hygon or Phytium domestic processors, a receiver equipped with an all‑domestic BeiDou chip, and firmware that is independently developed at the underlying level, free of any closed‑source foreign components. The device also supports… NTPv4、 IEEE1588 PTP Precision timing protocol, multi-channel 10G SFP Expansion ports, designed to meet the high-density synchronization requirements of large-scale domestic server clusters, complete system 1U Rack‑mount design, compatible with the standard dimensions of domestically produced XinChuang server cabinets.

III. Core Technical Parameters and Functional Advantages

1. XinChuang Compatibility: Native Compatibility with Phytium FT , Hai Guang HG Full series CPU , compatible with Kylin V10 , UnionTech UOS Server operating system, paired with domestically developed operations and maintenance management software;

2. Timing Accuracy: Timing Accuracy of a Multi-Mode BeiDou Receiver ≤20ns , support PTP Hardware timestamping, with distributed cluster synchronization jitter kept within the hundred-nanosecond range;

3. Security Management: Hierarchical administrator permissions, comprehensive retention of operation logs, SSH Encrypted remote login, anti- DDOS Time‑synchronization request attack mechanism;

4. Redundant design: dual power supplies, dual independent time‑synchronization network cards, and optional dual satellite receivers; automatic switchover to backup links in the event of a single-point failure.

IV. Deployment Architecture and Implementation Process

1. Core deployment of the indigenous innovation data center: two units in primary‑standby configuration. DNTS-9HG As a primary clock source, it connects to a Beidou satellite antenna to obtain standard time.

2. Cluster synchronization and distribution: via PTP The protocol is compatible with domestic databases, distributed storage systems, and homegrown virtualization platforms. NTP The agreement provides office terminals and monitoring equipment.

3. XinChuang Platform Integration: Devices SNMP The management protocol is adapted to the domestic operations and maintenance monitoring platform, and time-series data is centrally ingested into the indigenous innovation–compliant security audit system.

4. Monitoring Platform Integration: Integrates with an intelligent, network-wide unified time‑synchronization monitoring platform, providing visualized display of synchronization deviations across the domestic cluster network.

V. Compliance Alignment and Industry Certification

The product has obtained software–hardware compatibility certification from the Information Technology Innovation (ITI) Industry Alliance and complies with the “Financial Industry ITI Infrastructure Construction Specifications” and the “Technical Requirements for Domestic‑Based Transformation of Party and Government Organs.” Its time‑series logging meets the requirements of the Cybersecurity Classified Protection Scheme. 2.0 Level-3 audit standards.

VI. Real-World Application Cases

The six major state-owned banks have carried out large-scale deployments of provincial-level data centers in multiple regions, as well as domestically developed IT infrastructure server rooms at the headquarters of central enterprises. DNTS-9HG , the replacement of the original imported time‑synchronization equipment has been completed, and integration with domestically produced Phytium and Hygon server clusters has been achieved. Time‑synchronization for high‑frequency trading and core business systems is now stable, and the project has successfully passed the domestic‑technology‑innovation‑based localization acceptance on the first attempt.

VII. Operations and Maintenance Management and Full-Lifecycle Service Assurance

The original manufacturer provides dedicated technical debugging services for the XinChuang environment. 7*24 Hourly technical support for XinChuang solutions; continuous firmware updates to ensure compatibility with the latest domestic operating systems; a three-year full‑machine warranty, with direct replacement of the entire unit in case of failure; and annual specialized inspections of XinChuang‑compliant data centers.

Conclusion

DNTS-9HG Achieving full-stack domestication of time‑synchronization equipment and establishing a seamless time‑synchronization link among domestically produced chips, operating systems, and industry‑specific business systems makes this solution the standardized, compliance‑compliant core hardware for all types of information‑technology innovation (ITI) transformation projects.
