Abstract

The invention provides a method and a device for processing data and a storage system. The data storage system comprises at least one storage server and at least one SMR (shingled magnetic recording) disk. The SMR disks are connected with the storage servers; a plurality of storage zones in second storage regions of the SMR disks are classified as a plurality of storage groups, each storage group comprises at least one storage zones, and each optional storage zone only belongs to the single corresponding storage group; at least one write task currently to be processed can be acquired by each storage server and comprises to-be-written target data and identification of the corresponding target storage groups, the different write tasks comprise the identification of the different target storage groups, and the target storage groups and the target SMR disks where the target storage groups are located can be determined by the storage servers; the target data can be written into the storage zones corresponding to the target storage groups in the target SMR disks. According to the scheme, the method, the device and the storage system have the advantages that the write performance of the SMR disks can be improved, and accordingly the write performance of the storage system on the basis of the SMR disks can be improved.

Description

technical field

[0001] The present application relates to the technical field of data storage, in particular to a data processing method and device and a storage system. Background technique

[0002] In current storage systems, storage media such as solid state drives (SSD, Solid State Drives) and enterprise disks are generally used for data storage. However, the capacity of storage media such as SSDs and enterprise-level disks is relatively limited. With the gradual increase in the amount of data to be stored in storage systems, people hope to increase the storage capacity of storage media while keeping the size of the storage media unchanged. To this end, people have developed shingled magnetic recording technology.

[0003] The shingled magnetic recording technology has changed the structure of the storage medium. By overlapping the tracks, the data storage method has been readjusted, and the track password and storage density per unit area have been improved. However, ...
