Example Embodiment

[0078] In order to make the technical problems, technical solutions, and advantages to be solved by the embodiments of the present invention clearer, a detailed description will be given below with reference to the drawings and specific embodiments.

[0079] To ensure that data is synchronously written into the primary data center and the backup data center in real time, it is necessary to first describe the architecture of the disaster recovery system including the primary data center and the backup data center.

[0080] In the embodiment of the present invention, the disaster recovery system including the active data center and the standby data center is divided into four parts, wherein the standby data center is configured according to a certain proportion of the active data center according to the specific requirements of disaster recovery, such as figure 1 Shown include:

Abstract

The invention provides a disaster tolerance processing method and device, a main data center and a backup data center. The disaster tolerance processing method comprises the steps that a second logic unit number, sent by the backup data center, of a second storage subregion is obtained through a channel between a first storage region network and a second storage region network; a first logic unit number and a second logic unit number of a predetermined first storage subregion are added into storage configuration of a first virtual machine; according to the storage configuration, an operation system for file systems corresponding to the first storage subregion and the second storage subregion is established on the first virtual machine; data of a first application are synchronously written into the first storage subregion and the second storage subregion through independent disk redundancy RAID of the operation system. By means of the disaster tolerance processing method and device, the main data center and the backup data center, it can be ensured that the data can be synchronously written into the main data center and the backup data center in real time, and the zero loss of the data is ensured under the situation of a disaster of the main data center.

Description

technical field [0001] The present invention relates to the field of disaster recovery processing, in particular to a disaster recovery processing method, device, primary data center and standby data center. Background technique [0002] With the rapid development and maturity of cloud computing technology, a typical application of major IT companies is to use virtualization technology to build infrastructure as a service (IaaS) resource pools, and deploy business systems to the resource pool environment. Transformation and migration to achieve unified scheduling and management of resources, flexible application, improve resource utilization, and reduce total cost of ownership (TCO). As the resource provision layer in the enterprise cloud computing architecture, the IaaS resource pool undertakes important responsibilities for resource provision, business deployment, data storage, service provision, and security management of the entire cloud computing architecture. For core...
