Problems solved by technology

[0006] However, in the prior art, two nodes in the same I / O Group are respectively set in two sites, so when one of the sites fails, a corresponding node in the I / O Group is damaged, causing The reading and writing of another node enters the pass-through mode, which reduces the data processing speed and degrades the performance of the entire system

Abstract

The invention discloses a disaster recovery system comprising a network layer, a virtual layer and a storage layer, wherein the virtual layer is used for switching a service system from a faulty site to a standby site in the case of a site fault; the storage layer comprises storage devices arranged in different sites; two controllers of the same storage device are used as nodes to form an I / O Group; and the different storage devices keep data synchronization through HyperSwap. According to the disaster recovery system, the HyperSwap architecture is established to set the two nodes of the same I / O Group in the same site, therefore in order to handle the site fault, the service system is switched from the faulty site to the available site forming data synchronization with the faulty site, and thus the node of the I / O Group can be prevented from entering a read-write direct communication mode, and thus the processing performance of the system can be guaranteed while the disaster recovery is realized.

Description

technical field [0001] The present application relates to the technical field of virtualization, in particular to a disaster recovery system. Background technique [0002] With the continuous advancement of information technology, especially the rapid development of virtualization, big data, cloud computing and other technologies, IT information technology and systems have been widely used and penetrated into all walks of life in society, and massive amounts of data are generated every day. Therefore, the issue of data security is very important. [0003] With the development and popularization of virtualization technology, more and more data such as core business are stored in the virtual platform to increase business intensity. Virtualization technology is a technology that concentrates multiple application servers on one physical server in the form of VM (Virtual Machine, virtual machine). The use of virtualization technology can improve resource utilization, and it also...
