Problems solved by technology

If the local storage system does not support the consistency group function, it is impossible to implement consistent services in the software-defined storage system, which limits the compatibility of the software-defined storage system with the storage system layer
Even if the local storage system supports the consistency group function, the consistency group of the consistent service must be assigned to a single local storage system, that is, the consistent service can only be realized in a single local storage system, which will cause the The load of the storage system is unbalanced and the utilization efficiency is low

Embodiment Construction

[0062] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

[0063] The embodiment of the present invention provides a software-defined storage system that can create consistency groups and implement consistent services, as shown in the attached figure 2 shown. The consistent service may be a consistent snapshot, a consistent clone, or a consistent remote replication.

[0064] as attached figure 2As shown, the software-defined storage system includes a host layer, a middleware layer and a storage system layer. Between the host layer and the middleware layer, between the middleware layer and the storage system layer can be connected through a network. The host layer may include multiple hosts, and any one of the multiple hosts includes at least one host application. In the embodiment of the present invention, the host application can send an operation command to the m...

Abstract

The embodiment of the invention discloses a method, device and system for creating a consistency group in a software definition storage system. The method comprises the following steps that a server receives a consistency group creating command sent by a host, wherein the consistency group creating command comprises the name of the consistency group to be created, the number of group members of the consistency group to be created and marks of the group members in the server; the server determines that the group members are all in an available state according to the marks of the group members in the server; the server creates the consistency group, and returns a notification message of the consistency group creating success to the host. The method, the device and the system provided by the embodiment of the invention have the advantages that the creating of the consistency group in a middleware layer server of the software definition storage system is realized; the unified management and distribution of the server on a local storage system is realized; the extra-creating of the consistency group in the local storage system is not needed.

Description

technical field [0001] The present invention relates to the technical field of software-defined storage, and in particular to a method, device and system for processing consistent services in a software-defined storage system. Background technique [0002] Software defined storage (Software defined storage) technology enables storage functions to exist independently of hardware by providing standard interfaces, unified resource pools, integrated automatic management, virtual data paths, separation of control planes and data planes, and realizes geographical dispersion and type Unified management of heterogeneous storage systems with different performance, and provide flexible storage services externally. [0003] A software-defined storage system generally includes a host layer, a middleware layer, and a storage system layer. figure 1 shown. The middleware layer provides a unified interface and automatic management, and pools the storage system layer resources to shield th...
