Problems solved by technology
[0005] During the above-mentioned data writing process, the CPU in the storage node also needs to determine the hard disk LBA corresponding to the virtual address space to determine the hard disk to be written, and the hard disk to be written must be based on the relationship between the hard disk LBA and the physical address. The mapping relationship can determine the physical address space to be written, and write the data to be written into the determined physical address space. Therefore, the process of writing data to the storage node is more complicated, which increases the delay of writing data and reduces the improve the efficiency of writing data

Embodiment Construction
[0104] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0105] figure 1 is a schematic diagram of a storage system provided by the embodiment of this application, see figure 1 , the storage system 100 may include at least one metadata node 101 (for example figure 1 Metadata nodes 101a, 102b, and 102c in ), at least one client 102 (such as figure 1 clients 102C1, 102C2 and 102Cp in , where p is greater than 2), and a plurality of storage nodes 103 (for example figure 1 storage nodes 103S1, 103S2, 103S3 and 103Sq in , wherein q is greater than 3).
[0106] The at least one metadata node 101 is configured to manage storage devices in each storage node 103 in the storage system 100 . When the storage system 100 includes multiple metadata nodes 101, each metadata node 101 is used to ma...

The invention discloses a storage system, a data processing method and device, a node and a storage medium, and belongs to the technical field of data storage. According to the method, the address in the storage unit used for storing the to-be-written data is determined through the client side, the to-be-written data is sent to the first storage device corresponding to the storage unit in the storage node, the first storage device stores the to-be-written data, a CPU of the storage node does not need to determine a hard disk LBA corresponding to a virtual address space, and the hard disk does not need to determine the corresponding physical address according to the hard disk LBA, so that the time delay of writing the data is reduced, and the data writing efficiency is improved.
Description
[0001] This application claims the priority of the Chinese patent application with the application number 202010220314.8 and the title of the invention "A Storage System Access Method and Storage System" filed on March 25, 2020, the entire content of which is incorporated by reference in this application. technical field [0002] The present application relates to the technical field of data storage, and in particular to a storage system, data processing method, device, node and storage medium. Background technique [0003] With the development of data storage technology, more and more data can be stored in a storage system including clients, metadata nodes and storage nodes. [0004] At present, the process for the client to write data in the storage system can be: the metadata node allocates a virtual address space for the client; the client can send the allocated virtual address space and the data to be written to the storage node, and the storage node The processor (cent...
