Abstract

The embodiment of the invention provides a remote dual-active method for a distributed data center, which is applied to two storage servers. The storage equipment is managed by at least one storage server. The method comprises the following steps: receiving an access request for data located on a storage device, and requesting to establish a first type of access path with a storage server; And when the establishment of the first type of access path fails, establishing a second type of access path with the storage device according to the content of the access request. When the storage device cannot be accessed through the virtual storage platform, the storage device is directly accessed according to the access request, the content and format of data in the storage device cannot be changed,and path redundancy of data access is achieved. When one of the two storage servers breaks down, the storage service is automatically switched to the redundant server, and when the fault is repaired,storage data synchronization of the two servers is achieved through automatic reverse synchronization, so that data redundancy of data access is achieved.

Description

Technical field [0001] The invention relates to data disaster tolerance technology, in particular to a data protection strategy based on redundant system backup. Background technique [0002] The storage device is connected to the virtual storage platform in a transparent migration mode, and is managed by the storage server in the virtual storage platform. The access request to the storage device first passes through the storage server of the virtual storage platform, and then the virtual storage platform forwards the access request to the storage device . [0003] The prior art has the following problem: the storage device is taken over in a transparent migration manner, and after the access request reaches the storage server of the virtual storage platform, if a failure occurs, the access to the storage device cannot be realized. Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a distributed data center remote active-acti...
