Benefits of technology

This patented technology describes how applications that share physical resources like memory may be used together by multiple VMs without being affected by any changes made on their own machine (VM). However this approach does not capture all relevant associations for different types of resource usage patterns such as CPU utilization efficiency. Additionally it introduces new concepts called Software -Defined Solid State Disk Cache (SDSC) which allows dynamic controllers to manage storage capacity based upon factors like work load demands and users' preferences. Overall, this innovation helps optimize data processing performance while ensuring efficient operation across various computing environments

Problems solved by technology

Technologies described include techniques like caching memory systems and object oriented computing technologies called Multi-Level Chip Scale Compute Platforms (MCP). These technical features improve efficiency and reliance times over traditional servers while ensuring fairness across various VMs served within the system. Additionally, they aim to optimize both execution speed and input/output operation timing simultaneously considering factors like peak CPU requests and IO transfer rates.

Embodiment Construction

[0087] The present invention will be described in more detail below in conjunction with specific embodiments and accompanying drawings.

[0088] The present invention proposes a cloud application-aware solid state disk cache management method and system. This system is mainly composed of control module, monitoring module, analysis module, decision-making module and execution module. Its main deployment modes are as follows: figure 1 shown. The control module is deployed on an independent virtual machine or physical machine, coordinates the monitoring module, analysis module, decision-making module and execution module to complete the execution of the adaptive closed-loop, and triggers a new round of self-adaptation when a sudden change in the cloud application workload is detected Closed-loop execution. The monitoring module is deployed on the Hypervisor and the virtual machine, and is used to collect the performance information of the Hypervisor and the virtual machine, includ

Abstract

The invention relates to a cloud application-guided solid state disk cache management system and method. A core concept is characterized in that from the view of a cloud application, mapping relationship between virtual machines and a solid state disk is depicted by a multilayer network model; optimal solid state disk cache size obtained by each virtual machine is further determined. When the workload of the cloud application changes, the system can automatically trigger a regulation process to execute the dynamic migration and the cache capacity change of the virtual machines, so that the performance of the cloud application is improved, and the utilization rate of the solid state disk is improved.
