Embodiment Construction
[0029] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0030] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.
[0031] figure 1 It is a schematic diagram of the application scenario of the embodiment of the present invention. exist figure 1 Among them, the client 100 communicates with the management node 200, and the client 100 first sends a file operation request (for example...

The invention is applicable to the technical field of data storage, and provides a file storage and updating method and device, and the method comprises the steps: receiving a file write-in request sent by a client, and extracting data block information in the file write-in request; and acquiring state information of the storage nodes, screening the storage nodes according to the state informationof the storage nodes, and generating storage address information. The embodiment of the invention provides a file storage and updating method and device. A file needing to be stored is divided into aplurality of data blocks through a client; a storage address is distributed to each data block through a management node; the management node does not need to participate in time-consuming file partitioning and specific data block storage work; according to the method and the system, multiple tasks originally executed by the management node are transferred to the client and the storage node, so that the workload of the management node is greatly reduced, the access delay of the client is avoided, and the problem of relatively long access delay of a distributed file system in the prior art issolved.
Description
technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a file storage and update method and device. Background technique [0002] As the price of unit storage space continues to decrease, people tend to save more data, hoping to use more advanced data analysis tools to mine value at some point in the future. However, the storage media from ancient times to the present cannot solve the problem of data security and persistent storage. Therefore, to establish persistent storage on fragile storage media, it is necessary to use corresponding strategies and technologies. At present, whether it is an individual or a company, the amount of data continues to grow, and the problem of data storage is becoming increasingly prominent. Generally, enterprises use centralized storage and use disk mirroring to improve limited data reliability, but the capacity they can provide is limited. There are also some enterprises that use NA...
