Dual-active disaster recovery system with read-write separation function

Abstract

The invention discloses a dual-active disaster recovery system with a read-write separation function. The dual-active disaster recovery system comprises a network layer, an application layer, a data layer and a storage layer which are sequentially cascaded, wherein the network layer provides a channel for a user to access a service system; the application layer dynamically displays all software and hardware resource states and the alarm information in the system in a unified interface through the unified graphical interface; the data layer comprises two active data centers which are used for carrying out the unified organization and management on business data; and the storage layer is used for providing storage, synchronization and copying functions. According to the system, the redundantstandby resources are utilized to construct a layer-by-layer dual-active disaster recovery system with a main data center at the network layer, the application layer, the data layer and the storage layer remotely, and meanwhile, the read-write separation of the main data center and the standby data center is realized by utilizing a read-write separation cluster, so that the load of the main datacenter is reduced.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a dual-active disaster recovery system with a read-write separation function. Background technique [0002] With the widespread use of information technology, more and more important data are stored electronically in data databases. Although this method can improve convenience, it is also prone to data loss. Especially as the degree of informatization becomes higher and higher, the business of enterprises depends more and more on the continuous and stable operation of information systems, which makes irresistible disasters (such as earthquakes, tsunamis and other destructive events and human factors, etc.) It will have a huge impact on the data and business of the entire information system, and even cause a devastating blow to the enterprise. In the prior art, active and standby data centers with redundancy settings are widely used to quickly switch to the st...

Problems solved by technology

This method has certain shortcomings: the redundant server and the working server are set in the same computer room, which can avoid failures and data loss caused by disasters affecting the local area, and the backup and recovery of data by the redundant server will affect the work to a certain extent. The normal work of the server; in addition, the user's read and write operations are all on the same server, causing the main server to be overloaded and prone to downtime and service interruption.
