Method and device for data storage

Abstract

The embodiment of the invention provides a data storage method and storage equipment. The method is applied to the storage equipment and comprises the following steps that: the storage equipment receives a write request message, wherein the write request message comprises data and the keyword of the data, and the keyword is used for identifying the data type of the data; the storage equipment determines the data type of the data according to the keyword; then, the storage equipment searches a target physical storage block matched with the data type according to the data type, wherein the target physical storage block is a physical storage block of which the physical address is continuous; then, the storage equipment stores the data to the target physical storage block; and the storage equipment determines the data type of the data according to the keyword, and stores the data of the same data type into the target physical storage block of which the address is continuous so as to prevent from randomly storing the data of the same type. If the data of the same type needs to be searched or accessed, not all stored data need to traversed, data searching and accessing time is shortened, and data searching and accessing efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of storage, and in particular, to a data storage method and device. Background technique [0002] During the process of transmitting user data to the storage device, there are objective and unavoidable factors that affect the transmission of user data, resulting in delays in receiving user data. Therefore, for multiple user data of the same type sent at the same time, the receiving time of the storage device is discontinuous. There is a time interval between the receiving times of the two user data of the same type that are received twice adjacently. During the time interval, if the storage device receives other types of user data, the storage device sequentially stores other types of user data according to the receiving time, and the user data of the same type in the storage device The storage locations are scattered and spaced apart by the other types of user data, forming discontinuous stora...

AI Technical Summary

Problems solved by technology

[0003] When looking for the same type of user data, in order to avoid missing some of the same type of user data, the storage device traverses all the user data stored in it. Since the traversal rules are various, it is impossible to determine the random storage of the same type of user data. A traversal rule can quickly find the same type of user data

In addition, if the same type of user data is stored on different storage media, and each storage medium corresponds to a different access channel, the storage device needs to switch access channels multiple times to find the same type of user data stored on different storage media , leading to an increase in access time
