Disk tree optimization method and system in a virtualization platform

Abstract

This application discloses a disk tree optimization method in a virtualization platform, including: judging whether the original disk tree meets the preset optimization conditions; All the data in is merged into the new node; using the data mapping relationship, put the new node into the corresponding position of the original disk tree to obtain a new disk tree. It can be seen that after the original disk tree meets the preset optimization conditions, the application merges the data in each target node that needs to be optimized into the new node, and then utilizes the data stored in the target node and the data stored in the parent node. According to the data mapping relationship, a new disk tree is obtained, and the disk tree is optimized to reduce the depth of the disk tree, improve the speed of the virtual machine to access the disk, and ensure the high-performance operation of the virtual machine. In addition, the present application also discloses a disk tree optimization system in a virtualization platform.

Description

technical field [0001] The invention relates to the technical field related to server virtualization, in particular to a disk tree optimization method and system in a virtualization platform. Background technique [0002] Currently, there are many mainstream server virtualization products on the market, and the core module of many server virtualization products—virtual machine management—also covers common functions such as virtual machine lifecycle management, virtual machine snapshots, template creation, and virtual machine cloning. However, the virtual disk associated with the virtual machine has a large disk size due to long-term data writing operations. If a single-disk full operation is performed on the disk associated with the virtual machine, the above operations will take too long. To avoid this Problem, in the disk processing step of performing the above functions, use the method of linking the new disk, that is, create a new disk, link the original disk to the new...

Problems solved by technology

Although this disk processing solution can greatly reduce the operation time of the management platform, reduce user waiting, and improve user experience, if there are too many snapshots or too many virtual machines that are quickly cloned, the tree structure of the disk will become very difficult. Deep, when the virtual machine reads the disk content at the top of the tree, the speed will be reduced. If the disk I / O (I / O, Input / Output, input / output) is seriously low, it may cause the internal application of the virtual machine to fail. use, causing unnecessary losses to users
