K-UNIX Operating System

K-UNIX is based on Linux kernel self-developed operating system, focus on key applications, through UNIX 03 certification, means that the K-UNIX entered the key application software club.

Unix03 is called the Open Group UNIX 03 certification, which is the entry card of the key application software ecosystem. At present, UNIX is still the de facto standard for key application software. Not only is most of the key application software developed based on the UNIX standard, but also the key application software has the longest and most mature running time on the UNIX platform, therefore, it is necessary to open up the key application host market and enter the UNIX Software Technology ecosystem. However, this authentication is complex and requires a high threshold, only products from four vendors, IBM, HP, apple, and Oracle, have passed this certification.

UNIX 03 is the operating system's compliance certification for sus V3 standards. It consists of a series of standards for system calls, library functions, compilers, and so on. It must undergo more than 3200 UNIX compatibility enhancements, more than 60 thousand UNIX 03 testing items are passed.

Multiple Fault-Tolerant Technical Systems

As an operating system specially designed for key application business development, K-UNIX not only has been specially optimized for the ccnuma architecture, the performance has been greatly improved, but also has outstanding performance in security and fault tolerance.

The only UNIX operating system in the world that implements Multi-copy kernel and multi-copy shared library. Create core and shared database copies on each NUMA node to ensure that applications always access the local operating system kernel and shared database, avoid remote memory access across nodes, and significantly improve the overall system performance; multi-level scheduling domain, multi-copy, DMA localization, and other architecture-oriented optimization technologies improve system performance by nearly 270%

The core of the operating system that implements the driver protection framework. Build a driver isolation layer between the driver program and the operating system kernel to implement strict access control for the internal kernel area. Support for driver Fault Detection and recovery, and automatically identify and reinitialize failed driver modules; the system provides an isolated operating environment for device drivers and fundamentally solves the potential threats to the system caused by poor drivers.

K-UNIX has the core of the operating system of the intelligent fault management framework, and fully supports the advanced intelligent features of hardware.

1. Locate faulty parts and identify the impact scope, isolate the fault domains, and ensure the availability of the entire system;

2. Fault Prediction Based on Operation Records, resource fault Association descriptions, and diagnostic rules;

3. Monitors and automatically handles more than 120 types of faults including CPU, memory, PCIe, ioh, disk, and applications;

4. system software, such as the operating system and system firmware, is customized and optimized for the architecture. The fault tolerance system combining software and hardware is realized, ensuring the service continuity of the system.

Key application hosts are generally used as the bearer platforms for high-end key applications. The characteristics of such applications are the extremely high transaction processing pressure, such as the settlement system of banks, tens of thousands of transactions have to be processed every day. Second, the business cannot be paused. Unexpected shutdown may cause serious consequences, multiple Industries have put forward clear requirements on the continuous running time of key application hosts.

Tissot K1 adopts fault diagnosis, fault isolation, self-healing, hot replacement, multiple Fault-Tolerant technologies, such as automatic alarms, high Availability of 99.9994% is provided to ensure that the system can automatically diagnose, cure, or isolate faults without affecting external services. In addition, the K-UNIX with outstanding fault tolerance capability and Tissot K1 constitute a high availability integrated solution.
