Heterogeneous storage disaster recovery management system and method

Abstract

The present invention relates to a heterogeneous storage disaster recovery management system and method. The system includes: an application server and a storage server, wherein the storage server is used to provide the storage function of underlying heterogeneous resources and provide a storage interface to the application server; the application server includes: virtual machine; physical platform; a virtual machine monitor, used to virtualize the physical platform, and perform life cycle management, resource management and availability management of the virtual machine; the virtual machine monitor also includes: a soft RAID 1 management module, used for In the virtual machine monitor, the processing of input and output requests and the backup and disaster recovery processing of heterogeneous storage are realized; the storage resource pool management module is used to virtualize the underlying heterogeneous resources in the storage server and the local storage space in the application server Unified storage resource pool, and provide heterogeneous storage information to the soft RAID 1 management module. The invention can provide comprehensive and stable disaster recovery service for heterogeneous storage management under the 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 runs storagefoundation in the operating system, and realizes 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 performed on th...

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.
