Embodiment 1

[0035] In order to solve the problem of inaccurate positioning of the faulty machine when the traditional fault-tolerant computer system fails, this embodiment provides an arbitration system for key applications, which at least includes a self-test module, a heartbeat detection module, and an arbitration management module. Its architecture is as follows figure 1 shown.

[0036] Self-detection module, in order to improve the fault detection coverage of the system and ensure that the detection cost is reduced as much as possible, this paper introduces the self-detection module, which can detect the system's own faults by using the detection mechanism and fault detection algorithm that comes with the system. The detected fault information is sent to the arbitration management module as part of the basis for system diagnosis and switching.

[0037] Wherein, self-faults that can be detected by the self-detection module include faults such as power supply, CPU, fan, CPU board, arbit...

Abstract

The invention discloses an arbitration system and method oriented to critical applications, and belongs to the technical field of system arbitration. The arbitration system at least comprises a self-detection module, a heartbeat detection module and an arbitration management module. According to the self-detection module, a detection mechanism arranged in the system and a fault detection algorithm are used for detecting the self faults of a host system of a node, and the detected fault information is transmitted to the arbitration management module. The heartbeat detection module is used for detecting the state information of an opposite end node, and transmitting the detected fault information of other nodes to the arbitration management module. The arbitration management module is used for conducting final voting on double-machine nodes through an arbitration algorithm of the arbitration management module according to the fault information transmitted by the self-detection module and the heartbeat detection module. The invention further discloses the arbitration system oriented to the critical applications. According to the arbitration system and method oriented to the critical applications, a high fault coverage rate is achieved, and the requirement for high usability of the system is met.

Description

technical field [0001] The invention belongs to the technical field of system arbitration, and relates to an arbitration system and method for key applications. Background technique [0002] As an important means to improve the availability of computer systems, the meaning of fault tolerance means that the computer can still correctly execute the specified algorithm in the case of internal failures in the system. The fault-tolerant computer system is realized through redundancy. When a node in the system fails, the system can quickly find the faulty node and switch the service to other nodes. In a fault-tolerant computer system, the performance of the arbitration mechanism in finding faults, diagnosing faults, and reconfiguring the system directly affects the availability of the fault-tolerant computer system. That is to say, once a computer fails, whether the system can detect it in time, make a correct diagnosis and take corresponding actions is the key to the availabilit...
