Embodiment Construction

[0046] The suddenness and lag of system failures make it the killer feature of high-availability storage systems. How to effectively detect and predict failures and provide a flexible failure prediction mechanism has become the standard for measuring the high availability of storage systems. At present, in a high-availability storage system, the processing of a node's own failure is judged by other nodes in the system. If other nodes still cannot receive the heartbeat of the node within the timeout period, it will be considered that the node is faulty for fault handling and Resource switching. However, this method belongs to fault detection and fault reprocessing, that is, analyzing existing faults cannot predict the development trend of faults, which will delay the service interruption time and cannot meet the storage system with high availability requirements.

[0047] In order to solve the above problems, the embodiment of the present invention provides a storage system fau...

Abstract

The invention relates to the application field of computers, provides a storage system failure predicting method and a storage system failure predicting device, and solves the problem that existing processing methods cannot meet high requirements of high availability storage systems. The storage system failure predicting method includes collecting failure information of different failure types in a system; preprocessing the failure information of all the failure types respectively to obtain sub failure types under each failure type and failure occurrence time series corresponding to all the sub failure types; and predicting the next occurrence time of a failure corresponding to all the sub failure types. The technical scheme of the storage system failure predicting method and the storage system failure predicting device is suitable for the high availability storage systems, and high accuracy failure prediction is realized.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a storage system fault prediction method and device. Background technique [0002] With the rapid development of the Internet and e-commerce, network data information is showing an explosive growth trend. Storage network technology is increasingly accepted by enterprises and plays a very important role in their business activities. It is very important to build a high-availability storage network. If the storage network system fails, such as server failure or various equipment failures, system service interruption will result in loss of customers and loss of enterprise income. Studies have shown that in a network storage system, if the system is down for one hour, the enterprise will lose between US$150,000 and US$6.45 million. In order to ensure that the enterprise meets the application requirements of 24 hours * 365 days, it is necessary to build a highly available storage...
