Embodiment Construction

[0058] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be emphasized that the specific embodiments described here are only used to explain the present invention, and are not used to limit the scope of the present invention and its claims.

[0059] see figure 1 Shown is the structure of the fault-tolerant data storage method described in the present invention. Fault-tolerant data storage provides fault-tolerant data storage services through the application programming interface API provided to each process running in the server, where FTDS is the abbreviation of failure tolarent data storage fault-tolerant data storage.

[0060] The application programming interface API is established through the following functions:

[0061] 7.1) Process registration int regist (routine_name) is the process name;

[0062] 7.2) Submit the running data that needs to be saved with fault tolerance int commi...

Abstract

A data fault tolerant storage method under a multiserver environment relates to the field of distributed data storage. The method includes building an API (application programming interface), detecting server fault and synchronizing data. Detecting server fault refers to detection of whether a server in a network faults or not and is used fro detecting mainframe fault among server mainframes and separating faulted servers. Synchronizing data refers to discovery of drive state mainframes, synchronization of driven state mainframes and synchronization during operation and used for data fault tolerant synchronization among servers. By providing fault tolerant data storage service for APIs of progresses operated in servers, multiple server mainframes in a system can still provide external services when part of the servers fault, the problem of service stoppage, caused single server fault, of a small-medium size system operated in a client / server mode is solved, and certain redundancy is provided for system services.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to the field of distributed data storage, which can be used for fault tolerance in data storage in small and medium-sized network systems. Background technique [0002] The failure problem of the storage system has not been solved efficiently and practically. Once the storage system fails, the entire business system will be interrupted, or even cause data loss, causing irreparable losses to the enterprise or institution. Therefore, the solution to the failure of the storage device has gradually become an inevitable requirement of the information system in the field of data storage. This research can configure multiple servers and deploy the same program in the client / server system with demanding operating requirements. When some of these servers fail, the remaining servers can continue to provide services; realized The problem that the service cannot continue due to the failur...
