Description

Distributed storage service system and method based on desktop virtualization

Technical field

The invention belongs to the field of computer technology, and more particularly to a distributed storage service system and method based on desktop virtualization.

Background technique

As a unique group unit formed in the process of urbanization in China, the residential community (hereinafter referred to as the community), its information construction is still at the initial stage. For example, the information construction of most communities is composed only of access control and security monitoring systems. Although many companies are actively researching smart homes, they are limited to households, and lack information systems that connect the families from the overall layout of the community.

Applicants believe that based on the cell center server and desktop virtualization technology, the computing and storage service system for the community home users is a promising development direction.

Desktop virtualization relies on server virtualization, server virtualization on servers in the data center, and the generation of a large number of independent desktop operating systems (virtual machines or virtual desktops) that are sent to the end devices according to a proprietary virtual desktop protocol. The user terminal logs in to its own virtual host through the local area network, and only needs to remember the user name and password and the gateway information, so that it can access its own desktop system through the network anytime and anywhere, thereby realizing single-machine multi-user. If desktop virtualization technology is applied to a community-based environment, home users will no longer have to worry about PC hardware upgrades, software installations, and system maintenance, which will effectively improve the quality of life.

Applicant noted that in the existing desktop virtualization solution, all storage resources are uniformly allocated and managed by the virtualization server, and the storage resources managed by one virtualization server are uniformly allocated and scheduled by the server. This mechanism is more suitable for organizations such as enterprises with unified management practices and consistent resource owners. However, for families in a cell, users generally have their own private storage devices, and the public storage of the cell servers is physically separated from each other. In addition, users also want their private storage resources to have the highest possible privacy and can be directly controlled. Therefore, for the community environment, design a distribution suitable for desktop virtualization technology while meeting the needs of residential users. The storage service system will have the original innovative work and also have great practical value.

On October 15, 2015, the applicant filed a Chinese invention patent application entitled “A Storage Service Platform for Application and Virtualization Desktop Scenarios and Its Implementation Method”, which was published on January 13, 2016. For CN105245523A. The application proposes an architecture design in which a public storage device is separated from a private storage device. The public storage device is directly managed by the server virtualization system, and the storage resource is shared by all virtual machines on the virtualization server for storing user system files and applications. Program and configuration information; the private storage device is managed by a specific virtual host, and the private storage devices of each user are isolated from each other, there is no physical connection between them for storing the user's private data; the server virtualization system is authenticated and accessed by the user. The module is connected to a virtualized PC desktop service terminal established by each authenticated user. This application guarantees the responsiveness of the storage space and the security and scalability of the user's private data. However, the application gives an architecture that needs further refinement, while the flexibility, convenience and efficiency of computing and storage need to be improved.

For the virtual host 101 backup, only the server virtualization system 1 and the virtual host 101 are allowed to access themselves, and the user is not allowed to directly access; for the media library, the user is allowed to perform playlist customization and playlist-based operations; for the dedicated cache space, the user is allowed. The next-side broadcast is accessed, but the user is prohibited from storing locally during playback.

4) User file information table: maintain a data table, save user ID, password, private storage area address, corresponding virtual host, system backup file location, media library entry location, side broadcast buffer address, user uploaded file information, etc. .

As shown in FIG. 1, the virtual host 101 further includes a storage accessor 103, which is a software on the virtual host 101 in the server virtualization system 1 and is used to access the virtual host 101.
