Stored data processing method and apparatus and system

Abstract

A method, apparatus, and system for processing data storage. The method comprises: a processing device acquires a virtual address of data to be stored (S101), the data to be stored being located in a non-persistent storage medium of a storage control device; and the processing device sends the virtual address to the storage control device, so that the storage control device stores the data to be stored into a persistent storage medium of the storage control device (S102). By means of the method and apparatus for processing data storage, the storage control device can be directly controlled to store the data to be stored into the persistent storage medium of the storage control device according to the virtual address of the data to be stored, so as to achieve persistency of the data to be stored. Therefore, data persistency is widely applied in various scenarios, the problem that the persistency of the data to be stored cannot be achieved because a physical address of the data to be stored is not known can be avoided, and the performance of persistent data storage of a storage system is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a processing method, device and system for storing data. Background technique [0002] Usually computer equipment will store some data that does not need to be stored for a long time, such as the system operation log of the computer equipment, etc., but in some cases, it is necessary to store the above-mentioned data that does not need to be stored for a long time, that is, to persist the data; in the prior art Among them, when a process running on a computer device requests to persist data, it requests to write data from a non-persistent storage medium such as cache, DRAM (Dynamic Random Access Memory, Dynamic Random Access Memory) to a persistent storage medium (such as a disk ), the process needs to enter the kernel to register DMA (DirectMemoryAccess, direct memory access), obtain the DMA controller access authority, and then write the start a...

AI Technical Summary

Problems solved by technology

[0003] When adopting the above technical solution, it is found that the process needs to write both the physical source address of the data and the physical destination address for persistent storage of the data into the DMA controller, but in many application scenarios, the process on the computer device cannot Obtain the physical source address and physical destination address associated with the data, so the application range of the existing technology is small, and data persistence cannot be widely implemented, which will have a certain impact on the persistent storage data of various devices
