Heterogeneous storage disaster recovery management system and heterogeneous storage disaster recovery management method

Abstract

The present invention relates to a heterogeneous storage disaster recovery management system and a heterogeneous storage disaster recovery management method. The system comprises an application server and a storage server, wherein the storage server is used to store the bottom-layer heterogeneous resources and provide a storage interface to the application server, and the application server comprises a virtual machine, a physical platform, a virtual machine monitor used for virtualizing the physical platform and carrying out life-cycle management, resource management and availability management on the virtual machine. The virtual machine monitor also comprises an RAID1 management module used for realizing the processing of input and output request, the heterogeneous storage backup and the disaster recovery processing in the virtual machine monitor; a storage resource pool management module used for virtualizing the bottom-layer heterogeneous resources in the storage server and a local storage space in the application server into the unified storage resource pool, and providing the heterogeneous storage information to the RAID1 management module. The heterogeneous storage disaster recovery management system and the heterogeneous storage disaster recovery management method of the present invention can provide comprehensive and stable disaster recovery service for the heterogeneous storage management under a cloud computing environment.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a heterogeneous storage disaster recovery management system and method. Background technique [0002] In the existing cloud computing virtualization environment, virtual machines usually use heterogeneous data physical storage, but the current virtual machine monitor can splice multiple heterogeneous storages to form a unified storage resource pool and present it to users , but this method does not have disaster recovery capabilities. [0003] Symantec provides a heterogeneous storage management solution, which is to run storage foundation in the operating system, and achieve high availability among heterogeneous storage through the hard disk configuration (RAID1) of the soft mirror of the operating system and CPU . However, this solution requires an additional installation of storage foundation in the operating system, so disaster recovery management cannot be performe...

Problems solved by technology

However, this solution requires an additional installation of storage foundation in the operating system, so disaster recovery management cannot be performed on the system disk (disk C) of the Windows operating system

In addition, in a virtualized environment, the operating system of the virtual machine can only see the unified storage resource pool virtualized by the virtual machine monitor, and cannot recognize the heterogeneous storage environment. Therefore, it is difficult to determine whether to back up data when doing soft RAID 1. It is written to the same disk as the original data, which is easy to cause disaster recovery failure

[0004] At present, there is also a remote disaster recovery solution for storage virtualization, which is implemented by the storage management system itself. However, when the original data disk fails, the backup disk needs to be remounted to the host, and business interruption will occur during this process.
