Use method of distributed physical disk, and virtual machine

Abstract

The embodiment of the invention discloses a use method of a distributed physical disk, and a virtual machine. The virtual machine is applied to a distributed system containing N physical disks; each physical disk is located at one side of a host machine; a small physical disk in each physical disk is provided with a serial number; each physical disk is provided with a large physical disk identifier, and the small physical disk is provided with a small physical disk identifier; the large physical disk identifier is combined with the serial number of the small physical disk to obtain the small physical disk identifier. The virtual machine determines the identifier of a target physical disk, namely, the identifier of the large physical disk; the virtual machine directly sends a query request to the target physical disk, and splits the obtained target data according to a feedback result and sends the split target data to the corresponding small disk to store. Through the above mentioned realization scheme, the searching of the subsequent physical disk is convenient, and the congestion is reduced; furthermore, the data congestion probability can be reduced, the degree of parallelism of the data storage is improved, and the security of the data storage can be improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method for using a distributed physical disk and a virtual machine. Background technique [0002] A distributed storage system stores data dispersedly on multiple independent devices. [0003] Traditional network storage systems use a centralized storage host to store all data. The storage host becomes the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. The distributed network storage system adopts a scalable system structure, uses multiple storage hosts to share the storage load, and uses location hosts to locate and store information. It not only improves the reliability, availability and access efficiency of the system, but also facilitates expansion. [0004] 1. A virtual machine (Virtual Machine, VM) refers to a simulated virtual computer, that is, a logical computer. [000...

AI Technical Summary

Problems solved by technology

[0007] In a distributed system storage system, data needs to be stored on multiple independent devices. During this process, congestion often occurs and the storage speed is slow, so the overall data storage efficiency is low.
