Problems solved by technology
[0005] Because the distributed storage system deployed in this virtualization environment is often a third-party system, and when the distributed storage system stores data through the above method, it needs to rely on the physical address of each physical server and the The identity of the virtual machine, at this time, may reveal the location of each physical server and the distribution of virtual machines in each physical server, which may bring security risks to the physical server and reduce the stability and security of the physical server , also reduces the stability and security of the virtualized environment and the distributed storage system deployed in the virtualized environment

Embodiment Construction
[0061] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0062] figure 1 It is an architecture diagram of a distributed storage system in a virtualized environment shown according to an exemplary embodiment, refer to figure 1 , the distributed storage system includes a client, MDS and multiple SNs ( figure 1 Only show 8) and other software control terminals. In addition, the virtualization environment is built on multiple physical servers through virtualization technology, and several virtual machines are deployed on the multiple physical servers through a virtual machine manager. Any two physical servers among the plurality of physical servers may be connected through a network.
[0063] In the embodiment of the present invention, some or all SNs in the distributed storage system may be ...

The invention discloses a data storage method and device, belonging to the technical field of data storage. At least M virtual machines are deployed in multiple physical servers, and the M virtual machines are respectively deployed as M data nodes SN of the distributed storage system, and M is a positive integer greater than or equal to 2, and the method includes: distributing The MDS in the storage system can receive the client's data storage request, and determine the identifiers of N virtual machines according to the stored group information, because the group information records the mapping relationship between multiple anti-affinity groups and the identifiers of M virtual machines , without obtaining the physical addresses of multiple physical servers or the distribution of virtual machines in each physical server, therefore, the location of each physical server and the distribution of virtual machines in each physical server will not be disclosed, which improves the physical The stability and security of the server, thereby improving the stability and security of the virtualized environment and the distributed storage system deployed in the virtualized environment.
Description
technical field [0001] The invention relates to the technical field of data storage, in particular to a data storage method and device. Background technique [0002] With the development of electronic information technology, the amount of data in the network has increased significantly. In order to store and manage a large amount of data, various data storage technologies have emerged as the times require. Among them, the distributed storage system has been widely used for its security and convenience. [0003] A distributed storage system generally includes a client, a metadata node (Meta Data Server, MDS) and multiple data nodes (Storage Node, SN). The distributed storage system can usually be deployed in a virtualized environment, the virtualized environment is built on multiple physical servers through virtualization technology, and several virtual machines are deployed in the multiple physical servers through the virtual machine manager; The machine manager can be dif...
