Performance-grading-based storage mechanism suitable for cloud platform

Abstract

The invention relates to the field of cloud computing, in particular to a performance-grading-based storage mechanism suitable for a cloud platform. The storage mechanism includes the steps that LUN dividing is firstly carried out inside special storage devices, and storage resources are outwards provided in an SAN mode; then, LUN devices are found and logged in to, and the storage devices are localized; logical volume groups are created on physical servers through the localized devices and shared; after sharing on all the LUN devices is completed, when virtual machines are created, the storage devices are selected according to the requirements of the virtual machines for IO speeds, and then logical volumes corresponding to the sizes of hard disks of the virtual machines are created on the volume groups corresponding to the storage devices; images of the virtual machines are injected into the logical volumes created on the corresponding volume groups, and the virtual machines are created through the logical volumes. By means of the storage mechanism, the capacity of balancing IO load storage of the whole cloud platform is provided, and the cloud platform can be scheduled on the physical servers; the storage mechanism can be used for storage management of the cloud platform.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a storage mechanism based on performance classification suitable for cloud platforms. Background technique [0002] In the traditional mode, when large organizations carry out information construction, it is a common choice to purchase dedicated storage devices (such as IP-SAN, etc.) as storage devices; this can provide high-performance and high-reliability storage. With the development of storage technology and the continuous improvement of storage requirements for applications, large organizations will inevitably upgrade dedicated storage devices. Therefore, there are generally multiple dedicated storage devices of different generations and performance in these organizations. . How to make use of old specialized storage devices has always been a difficult problem. On the cloud platform, these devices are generally assigned to different clusters, and the physical servers mounted...

Problems solved by technology

[0003] 1. Under the cluster assigned to the low-performance storage device, due to the low IO speed, the physical servers under the cluster need to process relatively few IO requests, and the load of the entire cluster is relatively low; on the contrary, in Under the cluster allocated to the storage device with high performance, the load of the entire cluster is relatively high, the performance of the entire cloud platform cannot be balanced, and the processing efficiency of the platform is relatively low

[0004] 2. For the entire storage space, because the storage space is divided into different clusters, the use of storage space cannot be planned and scheduled at the platform level. Therefore, this method is likely to cause waste of storage space. In a single Fragmentation prone to occur on storage devices
