GBase 8s + Inspur K1 Power Joint Solution Drives the Localization of Urban Rail Transit

Currently, China is the world's largest urban rail transit market, and the booming new infrastructure initiative is accelerating the development of intercity high-speed railways and urban rail transit. According to statistics, 40 cities in mainland China have already opened urban rail transit operations, with over 208 operational lines and a total length of 6,736.2 kilometers. A further 65 cities are conducting preliminary work such as planning, design, and surveying for urban rail transit.

Renowned for its extreme punctuality, urban rail transit ensures that departure intervals during peak commuting hours are controlled precisely down to the second, greatly enhancing commuting reliability. Behind this is a robust suite of business systems operating in seamless coordination, underpinned by a highly stable, highly reliable, and highly available IT infrastructure platform. General Data Technology, in partnership with Inspur Power Commercial Systems, combines the strengths of the shared-storage database cluster GBase 8s and the high-end domestic server Inspur K1 Power to create a series of joint solutions. With outstanding O&M service capabilities, they support the rapid development of China's rail transit construction.

Integrated Supervision and Control System (ISCS) Joint Solution – Safeguarding Stable Urban Rail Transit Operations

During rush hour commutes, urban rail transit achieves departure and arrival times precise to the second—its operational stability is remarkable. The support of dozens of business systems centered on the Integrated Supervision and Control System (ISCS) and the high-reliability IT architecture platform on which they run are absolutely critical.

ISCS is a highly integrated automation monitoring system that uses a unified operating platform and comprehensive monitoring framework to achieve unified management of various basic data. It consists of a central-level integrated monitoring system, station-level integrated monitoring systems, and other auxiliary functional subsystems. It integrates six monitoring objects: substation automation system, environmental and equipment monitoring system, automatic fire alarm system, fiber-optic temperature sensing detection system, platform screen doors, and flood gates. It also interconnects nine monitoring objects: automatic fare collection system, access control system, public address system, closed-circuit television system, wireless communication system, passenger information display system, centralized communication alarm system, dispatch telephone, and signaling system.

By integrating these major low-voltage systems, a unified monitoring and management platform is created, enabling centralized monitoring and management of primary low-voltage equipment in urban rail transit—truly "eyes and ears in every direction." This allows for correlated monitoring of train operations, passenger flow statistics, and information sharing and coordinated interaction among related systems. Ultimately, it assists operations and management personnel in conveniently, efficiently, and in real time monitoring and managing the operations of the entire urban rail transit line.

GBase 8s + Inspur K1 Power = The IT Cornerstone of Urban Rail Transit

Urban rail transit carries millions or even tens of millions of passengers every day. Unplanned system downtime would cause incalculable losses, so the IT infrastructure underlying its ISCS must first and foremost possess extremely high availability and reliability. The Inspur K1 Power high-end server boasts the industry's highest RAS characteristics, with availability exceeding 99.999%, providing customers with a stable and reliable hardware platform that can operate continuously for 8 to 10 years without shutdowns or restarts—a fact widely proven in finance, telecom, and transportation industries.

Inspur K1 Power servers are built to the highest industry standards across design, R&D, manufacturing, and testing, ensuring continuous stable operation and resisting sudden failures caused by harsh physical environments such as sulfurization, high temperatures, and voltage fluctuations. Through redundancy, hot-swapping, and fault self-detection, the risk of unplanned downtime is greatly reduced, achieving high system maintainability. This has continuously provided a high-performance, reliable platform for metro operator A, significantly lowering ISCS downtime risk and economic losses.

Its advantages such as single-core multithreading, high processor bandwidth, and large L3 cache make it ideally suited for transaction processing in critical information systems. The General Data Technology GBase 8s database is China's first homegrown general-purpose database system matching world-class technology, capable of efficiently processing tables with hundreds of millions of rows. GBase 8s's shared-storage cluster (SSC) high-availability solution automatically switches nodes in the event of system failure, ensuring stability and high availability. The shared-storage dual-node cluster built on GBase 8s further guarantees the stability and high availability of station and line central data servers, achieving a 1+1>2 effect. Additionally, the advantage of localized services that respond quickly to user needs, along with high stability and high availability, not only fully meets the current application requirements of urban rail transit but also lays a solid performance foundation and resource reserve for future business expansion.

To date, joint solutions based on Inspur K1 Power and General Data Technology's GBase 8s have been deployed in the ISCS of dozens of metro lines. The operating lines have run stably without failure, earning unanimous praise from industry design institutes and integrators, and laying the foundation for the domestic localization of smart urban rail transit construction.

Driven by the growing demand for urban rail transit construction and the rising tide of big data, urban rail transit development is welcoming new transformations. The GBase 8s transactional database, with its high capacity, high concurrency, and high performance, together with Inspur K1 Power's high performance, high reliability, high security, and strong data consistency, will join forces with more partners to meet industry trends. Leveraging professional data management experience, they will help enable the construction and development of smart rail transit.
