Inspur TianSuo K1 950 System

Brief Introduction

is designed with a modular architecture and fully redundant technology to sufficiently

guarantee flexible deployment of your operational system and the optimal supply of high-performance, highly available and efficient IT resources.

Functional Features

Brand-new architecture and robust performances

Inspur Tiansuo K1 950 has a dual-wing expansion tight coupling structure with multi-faceted interconnection and redundancy and Internet-based 32-way mono-step expansion, effectively reducing the interconnection delay, enhancing system reliability and scalability and laying a solid architectural foundation for system high availability. This architecture lays the foundation for high availability of the system and it is also China’s first PCT design invention patent in key application mainframe architecture, making China the third country being capable of the independent R&D of Unix Server. Inspur Tiansuo K1 950 has 256 computing cores at most and can easily satisfy the performance requirements of key applications; its 4095GB memory expansion can conveniently support the applications that have strict requirements on memory.

Continued availability to ensure smooth operation

Inspur Tiansuo K1 950 has redundant and fault tolerant designs of hardware and software on all layers, including bottom-layer chip and module, system administration, operating system and even application. It provides strong guarantee to the high availability of the operating system with system availability reaching 99.9994%. It also ensures continued and uninterrupted operation of the system and can improve operational continuation and customer satisfaction. Inspur Tiansuo K1 950 provides multiple advanced RAS features, including memory mirroring and hot standby, MCA troubleshooting, dynamic re-distribution, operating system CC-NUMA optimization, out-of-band monitoring and administration irrelevant to system status, module hot-plug and redundancy, etc. These features help increase system availability, allow you to process more jobs and reduce operational downtime.

Redundant design and reliable guarantee

Single-point trouble is the major threat to system reliability. Inspur Tiansuo K1 950 has redundant and hot-plug designs for power supply, cooling, interconnection and computing modules so that the failure of any single module won’t affect the continued operation of the system. Inspur has also launched the Inspur K-HA high-availability cluster software for backup of the nodes and operations of the system, hence realizing the automatic detection and transfer of critical operation faults, eliminating single-point fault and guaranteeing the continuation of core operations. Combination of software and hardware ensures 7*24h continuous operations.

Stable system available on demand

The K-UX operating system tailor-made for Inspur Tiansuo K1 950 has passed 70,000 test items included in the Unix03 certification of the ISO and became the first and only domestic operating system to pass the international UNIX certification. It can provide sound stability and availability for the user. Only five enterprises, including Inspur, have the ability to develop UNIX operating system in the world.  The multi-core-copy technology of Inspur K-UX ensures system stability upon accidental change of the operating system’s core status. The synchronization and high-availability mechanism of core processes helps to reduce the switching time to microsecond level. The virtual operating environment of the drive provides an isolated operating environment for equipment drive and fundamentally addresses the potential threats of bad drives to the system. Meanwhile, Inspur K-UX operating system has been awarded with the “Computer Information System Safety Product Sales License” by the Ministry of Public Security. It conforms to the safety requirements of domestic safety standards on operating system and guarantees the independent control of the system.

Visualized administration and command on resources  

The well-established fault sensing, diagnosis, isolation and recovery mechanism of Inspur Tiansuo K1 950 is the core technology that guarantees high availability of the system. The faults can be rapidly identified through multidimensional fault detection technologies. Coupled with the unique fault administration framework of Inspur K-UX operating system, it can realize the smart diagnosis and analysis on common troubles of 120+ software and hardware. Inspur Tiansuo K1 950 has a user-friendly administration interface, which integrates system summarization, monitoring and administration, resource distribution, diagnosis and other functions so that the administrator can comprehensively manage the system remotely.

Fast partitioning and flexible application

Inspur Tiansuo K1 950 provides 8 physical partitions at the maximum. Each partition has independent hardware resources. The partition can be deployed with clusters or different applications. Physical partitions are isolated by electric-level hardware and each partition has an independent power supply module and time sequence control to guarantee independent operations of the partition. Partitioning is simple and takes only 3 steps and 5 seconds to complete. All Chinese display and graphical configurations help to improve administration efficiency by over 15%.

Extensive compatibility to guarantee reliable operation

Inspur Tiansuo K1 950 is highly and extensively compatible with mainstream peripheral equipment, databases, middleware and applications at home and abroad. It has undergone joint tests and mutual certifications with products of many other enterprises and can well satisfy the application needs of most clients. Inspur is committed to close cooperation with more partners of databases, middleware, utility software and applications with an aim to jointly promote the development of ecological chain of China’s key application mainframe sector.
