Problems solved by technology

In addition, this solution is complex and difficult to implement and maintain
The operating system is the most complex software, and the file system is one of the most basic functions in the operating system. Re-implementing a file system and adapting it to different operating systems makes the implementation of this solution extremely difficult, and correspondingly More maintenance efforts are required

Embodiment Construction

[0062] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0063] see figure 1 and figure 2 , are flow charts of the data storage phase and the data access phase in the data storage and access method described in an embodiment of the present invention; wherein, the data storage phase includes the following steps:

[0064] S11. The client initiates a request for the file to be uploaded to the coordination server;

[0065] S12. The coordinating server determines a storage server that can currently effectively execute the write operation through the heartbeat time verification process;

[0066] S13. The client obtains the IP of the storage server determined by the coordination server to be able to effectively execute the write operation, and uploads the file to the storage server.

Abstract

The inventor provides a method and system for data storage access that can provide support for multiple operating systems, good operating performance, high reliability, limited investment, and convenient maintenance while meeting the requirements for shared access to SAN storage. Including a data storage stage and a data access stage; the data storage stage includes the following steps: the client initiates a request for a file to be uploaded to the coordination server; the coordination server determines a storage server that can currently effectively perform a write operation through a heartbeat time verification process; The client obtains the IP of the storage server that can effectively execute the write operation determined by the coordination server and uploads the file to the storage server. Also included is a data access phase method. The system described in the technical solution of the present invention and the method for realizing it have the characteristics of high availability, high performance, cross-platform and easy implementation, and avoid the shortcomings of the existing mainstream solutions.

Description

technical field [0001] The invention relates to the field of computer internet, in particular to a method and system for data storage and access. Background technique [0002] Data storage systems are a key component of an enterprise's IT infrastructure. In the early days, data storage mainly relied on the computer's local hard disk. With the rapid development of information technology, the capacity and storage performance of local hard disks are far from meeting the needs of enterprise-level software systems. For example, database files generated by some database management systems may reach TB (1TB=1024GB) or even hundreds of thousands terabytes in size. The traditional practice of putting hard disks in the computer mainframe can no longer meet the storage capacity requirements of modern applications, which has given birth to network storage technology. [0003] Network storage technology means that independent devices provide data storage functions, and other computer ...
