Problems solved by technology

However, in the existing cloud host system, the disks of each cloud host generally clear the cache randomly when releasing the memory space, and the ability and concept of QOS (Quality of Service Assurance) have not been applied to it.

Embodiment Construction

[0039] A QOS-based cloud host disk resource guarantee method, comprising the following steps:

[0040] Receive the IO request of the virtual disk, and add the QOS identification with the QOS level of the virtual disk to which it belongs to the cached data of the response;

[0041] Scan the cached data and release and clear it according to its QOS level.

[0042] Further as a preferred embodiment, the cache data of the response is added with the QOS identification of the QOS level of the virtual disk to which it belongs, which specifically includes:

[0043] Reorganize the received IO request into a physical disk block IO request through the virtualization program;

[0044] According to the physical disk block IO request, read the cached data of the response from the memory;

[0045] Detect whether the cached data of the response has a QOS identifier, if so, do not need to process it; otherwise, add a QOS identifier with the QOS level of the virtual disk to which it belongs. ...

Abstract

The invention discloses a QOS-based cloud host disk resource guarantee method and system. The method includes: receiving an IO request of a virtual disk, and adding a QOS identifier with the QOS level of the virtual disk to which the response cache data belongs; scanning the cache The data is released and cleared according to its QOS level. The system includes: a sign adding unit and a space releasing unit. The present invention clears the cached data according to its QOS level, thereby releasing the memory space, thereby ensuring sufficient memory space, and at the same time guaranteeing the QOS service quality of the cloud host disk resources, effectively preventing the avalanche phenomenon of the cloud host system . The present invention can be widely applied in cloud host disk technology.

Description

technical field [0001] The present invention relates to cloud host disk resource technology, in particular to a QOS-based cloud host disk resource guarantee method and system. Background technique [0002] Cloud hosting is an IT infrastructure capability rental service that integrates computing, storage and network resources, and can provide server rental services based on cloud computing models with on-demand use and pay-as-you-go capabilities. Customers can deploy the required server environment through the self-service platform of the web interface. Cloud host is a new generation of host rental service. It integrates high-performance servers and high-quality network bandwidth, effectively solves the shortcomings of traditional host rental prices and uneven service quality, and can fully meet the needs of small and medium-sized enterprises and individual webmaster users. Host rental service needs low cost, high reliability, and easy management. [0003] Now, while cloud ...
