AI Technical Summary

Problems solved by technology

However, the layered storage solution based on LVM can only be implemented in the system kernel, which is difficult to develop, and can only implement layering based on block devices, not file-based layering. At the same time, metadata needs to be modified every time writing, resulting in Poor storage performance

Embodiment Construction

[0033] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0034] The embodiment of the present application provides a distributed-based data hierarchical storage method. For the defects of the existing technology, the principle of this embodiment is simple, does not need to consume a large amount of CPU resources and memory resources, and is easy to implement and apply in engineering. At the same time, distributed block storage or file storage can be layered, which can greatly reduce the cost of the storage system while improving the overall performance of the storage system, and the performance of data writing has also been improved.

[0035] figure 1 It is an architecture diagram of the distributed storage system in this embodiment. Such as figure 1 As shown, the distributed storage system includes: a control host 110 and a plurality of storage hosts 120...

Abstract

The invention provides a data hierarchical storage method, a reading method, a storage host and a storage system, and the method comprises the steps: obtaining to-be-stored data; writing the to-be-stored data into a first sparse file in a storage component, wherein the storage component is formed by superposing the first sparse file and a second sparse file which are the same in size, and the read-write performance of a first hard disk stored in the first sparse file is superior to the read-write performance of a second hard disk stored in the second sparse file. According to the method and the device, the two sparse files falling into the first hard disk and the second hard disk respectively are superposed to form the storage component, so the data can be directly written into the sparsefiles of the first hard disk during data writing, additional metadata does not need to be written, and the writing performance is greatly improved.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular, to a hierarchical data storage method, a reading method, a storage host and a storage system. Background technique [0002] With the advent of the information age, the amount of global data is in an explosive growth trend. With the rapid growth of data, the management difficulty of traditional data storage increases, and the cost performance decreases. And with the continuous advancement and popularization of solid-state storage technology, the types of storage media become more diverse, and the performance of storage devices using different storage media and interfaces varies greatly. Solid State Disk (SSD) compared with traditional mechanical hard disk (Hard Disk Drive, HDD), because there is no mechanical rotation of the disk, the addressing speed is greatly improved, especially in the application environment with more random reads and writes, the performance...
