Problems solved by technology
[0004] Although the amount of metadata data is small, with the increase in the number of data blocks and the number of storage nodes, a large amount of metadata needs to be stored locally. When storing and restoring data, a high amount of computation is required. Difficult to implement for storage or computing systems

Embodiment 1
[0085] In this embodiment, the circumference ratio π is used as the irrational number in the implementation method to clearly illustrate the method of the invention. Those skilled in the art know that the value of π is 3.1415926...; the number sequence of irrational numbers has no rules to follow and has strong randomness, and irrational numbers can also be obtained through calculation formulas in the data field, for example, it can be calculated by dividing 1 by π Get an irrational number.
[0086] In order to realize the storage of stored data, it is first necessary to set and determine the storage parameters. The start bit of the irrational number can be set randomly by the user. For example, the start bit is the third digit of the physical number, and the third digit of Start reading irrational numbers with the first preset number of digits. Assuming that the preset interval of digits is 0, the irrational numbers of the first preset digits are read one by one in order; th...

The invention discloses a data storage achieving method and device. The data storage achieving method comprises the steps that storage parameters of data storage are determined according to predetermined irrational number; stored data cut into data blocks are respectively written into corresponding storage nodes according to the determined storage parameters, and reduction parameter information is generated according to the written data blocks so as to perform data reduction according to the reduction parameter information during stored data reading. By means of the data storage achieving method and device, data storage is performed according to the predetermined irrational number and the storage parameters determined based on the irrational number, and data reduction processing is performed according to the reduction parameter information. Compared with metadata stored in an existing storage mode, data reading and reduction can be performed without saving of irrational number, storage parameters and reduction parameter information, and the calculation amount for data storage and reduction is reduced.
Description
technical field [0001] This application relates to cloud storage technology, especially a method and device for realizing data storage. Background technique [0002] Cloud storage is a new concept extended and developed on the concept of cloud computing. It is an emerging network storage technology. A large number of different types of storage devices work together through application software to jointly provide a system for data storage and business access functions. Many people understand cloud storage as storing data online, but it is not. When using cloud storage technology for data storage, the data is not necessarily stored in a fixed location on the network, nor is it necessarily stored in a complete file, and even the storage method is random. The most basic requirement of cloud storage is: the legal owner of the data After storing the data port must be able to restore the data from the storage location. [0003] At present, the basic method of cloud storage is to...
