Virtual machine storage resource deployment method and device

Abstract

Provided are a virtual machine deployment method and device. The method comprises: firstly acquiring a virtual machine storage resource description file, parsing the storage resource description file to acquire the storage performance requirements of the virtual machine, then calling an IaaS-layer management interface according to the storage performance requirements to set a logic unit number corresponding to the virtual machine, thereby meeting the storage performance requirements of the virtual machine. Compared with determining a corresponding data storage cluster according to the storage capacity of a virtual machine in the prior art, in the embodiments of the present invention, when deploying a storage resource, a logic unit number corresponding to the virtual machine is directly set according to storage performance requirements, and thus a person skilled in the art could flexibly configure a virtual machine storage resource description file, to avoid the case where a main and a standby virtual machine, and a data disk and a system disk of the same virtual machine, correspond to the same logic unit number in a data storage cluster, thus improving reliability of virtual machine storage resources, and having a relatively high configuration efficiency.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a virtual machine storage resource deployment method and device. Background technique [0002] Cloud computing is a pay-by-use model that provides available, convenient, and on-demand network access and access to a configurable shared pool of computing resources, including networks, servers, storage, and application software. In a cloud computing environment, virtual machines share physical storage space at the IaaS layer, such as solid state drives (Solid State Drive, SSD) and hard disk drives (Hard Disk Drive, HDD). [0003] In the prior art, when deploying a virtual machine, the cloud management system determines the corresponding data storage cluster according to the storage capacity requirements of the virtual machine. The data storage cluster includes multiple logical units, and each logical unit is represented by a logical unit number (LogicUnit Number, LUN...

Problems solved by technology

[0004] However, the virtual machine deployment method in the prior art is randomly allocated according to the capacity, which may cause the system disk and data disk of the virtual machine to correspond to the same logical unit number, or the virtual machines that are mutually active and standby correspond to the same logical unit number in the data storage cluster. Unit number reduces the reliability of storage, so the prior art letter needs to be improved
