GBase 8s and Inspur K1 Power Joint Solution Supports the Localization of Urban Rail Transit

China is now the world’s largest urban rail transit market, and the booming new infrastructure drive is accelerating the growth of intercity high-speed railways and urban rail systems. Statistics show that 40 cities in mainland China have launched urban rail operations, covering more than 208 lines with a total length of 6,736.2 kilometers. Another 65 cities are in the early stages of planning, design, survey, and consulting for urban rail transit projects.

Urban rail transit is prized for punctuality—especially during rush hours, when train intervals are controlled down to the second, significantly improving commute reliability. Behind this precision lies a tightly integrated ecosystem of business systems, supported by a highly stable, reliable, and available IT infrastructure platform. GBase (General Data Technology) and Inspur Power Systems have combined the strengths of GBase 8s, the China-developed transactional database, with the high-end Inspur K1 Power server to create joint solutions that deliver outstanding operational services and fuel the rapid development of China’s urban rail transit.

Joint Solution for Integrated Supervision and Control System

Safeguarding Seamless Urban Rail Operations

During peak commuting hours, urban rail transit achieves departures and arrivals with split-second precision—its remarkable reliability is underpinned by dozens of business systems centered on the Integrated Supervision and Control System (ISCS) and the highly resilient IT architecture platform that hosts them.

The ISCS is a deeply integrated automation monitoring system built on a unified operating platform and integrated monitoring mechanisms, enabling centralized management of diverse foundational data. It consists of a central-level ISCS, station-level ISCS, and auxiliary functional subsystems. The system unifies six directly monitored objects—substation automation, environmental and equipment monitoring, automatic fire alarm, fiber-optic temperature sensing, platform screen doors, and flood gates—and interconnects with nine additional monitored systems, including automatic fare collection, access control, public address, closed-circuit television, wireless communication, passenger information display, centralized communication alarm, dispatching telephone, and signaling.

By integrating these core low-voltage subsystems into a single monitoring and management platform, the ISCS delivers centralized visibility and control over critical low-voltage equipment across the rail network—a comprehensive, all-seeing nerve center. This enables correlated oversight of train operations, passenger flow statistics, and facilitates information sharing and coordinated interaction among related systems, ultimately empowering operations staff to monitor and manage the entire urban rail line conveniently, efficiently, and in real time.

GBase 8s + Inspur K1 Power

The IT Cornerstone of Urban Rail Transit

Urban rail systems carry millions — even tens of millions — of passengers daily. Unplanned system downtime can lead to incalculable losses, so the IT infrastructure supporting an Integrated Supervisory Control System (ISCS) must deliver extreme availability and reliability. Inspur K1 Power high-end servers are engineered with industry-leading RAS capabilities, achieving over 99.999% availability. They provide a stable, reliable hardware foundation proven to run continuously for 8 to 10 years without downtime or reboot, as widely demonstrated in the banking, telecommunications, and transportation sectors.

Inspur K1 Power servers follow stringent industry standards throughout design, development, manufacturing, and testing to ensure continuous, stable operation. They withstand harsh physical environments — including sulfurization, high temperatures, and voltage fluctuations — that can cause sudden failures. Through redundancy, hot-swap capabilities, and fault self-diagnosis, these servers dramatically lower the risk of unplanned outages and deliver high serviceability. They have consistently provided Customer A’s metro operations with a high-performance, reliable platform, significantly minimizing the downtime risk and economic loss of its ISCS.

The single-core multi-threading, high processor bandwidth, and large L3 cache make the platform exceptionally well-suited for transactional database processing in mission-critical information systems. GBase 8s from General Data Technology Co., Ltd. is the first Chinese-developed universal database system on par with global technology, capable of efficiently handling tables with hundreds of millions of rows. GBase 8s's high-availability solution built on SSC shared-storage cluster architecture automatically switches nodes when a fault occurs, ensuring system stability and continuous operation. A shared-storage dual-node cluster based on GBase 8s further strengthens the stability and high availability of data servers at both station and line-central levels, delivering a 1+1>2 effect. In addition, the rapid local support and service responsiveness, combined with high stability and availability, not only fully meet current urban rail application demands but also lay a solid performance foundation and resource reserve for future business expansion.

To date, the joint solution based on Inspur K1 Power and GBase 8s has been deployed on dozens of metro lines for ISCS. All lines in operation have run stably and fault-free, earning consistently high acclaim from design institutes and system integrators. This track record has laid the groundwork for the localization of smart urban rail transit construction.

As urban rail transit construction demand keeps growing and big data gains momentum, the sector is undergoing fresh development and transformation. With its high capacity, high concurrency, and high performance, the GBase 8s transactional database — together with Inspur K1 Power’s high performance, extreme reliability, robust security, and strong data consistency — will join forces with more partners to align with industry trends. Leveraging its specialized data management expertise, the partnership aims to drive the realization of smart rail transit development and evolution.
