Data storage management system and method

Abstract

The invention discloses a data storage management system and method, belonging to the technical field of hardware storage. The system comprises a flash memory conversion unit which executes mapping processing and RAID checking processing of logical addresses and physical addresses of stored data files in the flash memory conversion unit and is arranged in a driver of a computer. The writing unit applies the physical address of the physical page of the solid-state hard disk to the flash memory conversion unit according to the data writing request of the user to complete the writing operation. The reading unit requests the flash memory conversion unit to read the corresponding data file according to the user's data reading request to complete the reading operation. The technical proposal hasthe beneficial effects that RAID verification and other computing operations are carried out on the solid state disk by using the computing power of the host computer, the computing efficiency and the read-write performance of the solid state disk are improved, the idle computing power of the host computer is utilized, and the management of the solid state disk is more compact and reliable.

Description

technical field [0001] The present invention relates to the technical field of hardware storage, in particular to a data storage management system and method. Background technique [0002] As an emerging storage medium, solid state drives (SSD) have faster read and write speeds, lower shock resistance, lower power consumption, and lower operating noise than traditional mechanical hard drives. The operating temperature range is wider, and the shape is thinner and lighter than traditional mechanical hard drives. Therefore, with the development of storage technology, more and more storage solutions are implemented using solid-state drives. [0003] Existing high-end solid-state hard disks are basically solid-state hard disks based on flash memory, which are usually composed of a solid-state hard disk controller and a flash memory chip, and multiple flash memory chips form a RAID storage array of the solid-state hard disk. After data files enter the RAID array, they will be di...

AI Technical Summary

Problems solved by technology

[0005] 1) The computing power of the SSD controller is relatively weak, which limits the performance of RAID computing, thereby limiting the read and write performance of the SSD;

[0006] 2) The host and the solid-state drive are isolated from each other, so that the internal logic of the solid-state drive cannot be closely integrated with the host application;

[0007] 3) The idle computing power of the host is not utilized, resulting in a waste of host performance
