Problems solved by technology

In the production process, only the master end can provide business IO access to the upper-layer application, and the remote end cannot provide access to the upper-layer application. In order to accept upper-layer IO access, there is an uncontrollable risk in this process, and obviously the shortest recovery time is seriously uncontrollable

Embodiment Construction

[0012] Such as figure 1 The data of business application 1 shown in , is written to the active-active yellow logical volumes of the two storage systems, that is, the active-active yellow logical volumes of the two storage systems provide the same IO access to upper-layer application 1 at the same time. The two sets of data are completely synchronized in real time, and the status relationship between the two active-active logical volumes is equal. The upper layer does not perceive the existence of the two lower logical volumes, and considers it to be only one logical volume. The upper layer uses access to a virtual logical volume This enables dual-read and dual-write access to the two logical volumes. The failure of any logical volume will not affect the upper-level business application 1; similarly, for business application 2, it runs on the server in data center 2, and the corresponding data is stored on the blue logical volume. The paired active-active logical volume comes f...

Abstract

The invention provides a dual-active storage system design method based on dual-active logical volumes, which belongs to the fields of dual-active designs for storage system data, mirroring technology and disaster recovery and backup. By establishing the dual-active relation between logical volumes in two sets of storage systems, the two logic volumes provide the same access mechanism for the upper layer, so that the data of two data centers are the same in real time and the failure of any set of storage system does not affect the usage of the data centers at two places. Dual-active data access is realized, the risk of disaster recovery systems is decreased, service downtime is prevented, and the capability of a comprehensive solution is enhanced.

Description

technical field [0001] The invention relates to the fields of active-active data storage system design, mirroring technology, and disaster recovery backup. Specifically, it relates to a storage active-active system design method based on active-active logical volumes. Background technique [0002] On the basis of data protection, how to achieve the shortest recovery time of the faulty system determines the loss of production value. The shortest recovery time of the disaster recovery system has become the main measurement point for the robustness of the disaster recovery system, especially for the real-time requirements of the production system. High business and customers, such as financial customers, aerospace, etc. The traditional data protection method is to use synchronous or asynchronous mirroring on the storage side to realize data backup protection in two places, and to realize the recovery of the faulty system in combination with the configuration of the upper-level...
