Hypervisor Data Caching for Distributed Virtual Storage Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distributed virtual environments face limitations in providing large volumes of data storage and suffer from latency issues, making it difficult to offer satisfactory response efficiency for user access to virtual machines.
Innovation Solution
The solution involves caching data at a hypervisor node within the distributed virtual environment, notifying the user of completion, and then transmitting the cached data to a storage node for physical storage, allowing for efficient data access and scalable storage capacity while minimizing user wait time.

Engineering Contradiction Analysis
1Quantity of substance
If data is stored directly on storage nodes in distributed virtual environment, then storage capacity is extended, but access speed and response efficiency deteriorate due to network latency
Solution Approach 1:
The patent segments the storage system into two distinct components: local storage at the hypervisor node and remote storage on storage nodes. This segmentation allows the system to simultaneously achieve large storage capacity through remote nodes and fast access speed through local caching, resolving the contradiction between extended storage and access efficiency.
Solution Approach 2:
The patent introduces a caching mechanism as an intermediary between the hypervisor node and remote storage nodes. This cache acts as a buffer that stores frequently accessed data locally, mediating between the user's need for fast access and the system's need for large storage capacity, thereby eliminating network latency for common operations.
2Productivity
If data is cached at hypervisor node and user is notified of completion before data reaches storage node, then response efficiency is improved, but data consistency and reliability may be compromised
Solution Approach 1:
The patent implements preliminary action by notifying the user of write completion as soon as the data is cached at the hypervisor node, before the data is actually written to the remote storage node. This preliminary notification improves response efficiency while the system continues to write data in the background, eventually achieving full persistence.
Solution Approach 2:
The patent establishes a feedback mechanism where the system provides confirmation to the user upon successful caching of data, creating a responsive interaction loop. This feedback improves perceived system responsiveness while the asynchronous write process ensures eventual data consistency and reliability.
Data Source
AI summary
A mechanism is provided for managing data storage in a distributed virtual environment. A write access request to a virtual machine in the distributed virtual environment is received from a user, the virtual machine running on a hypervisor node in the distributed virtual environment. The data associated with the write access request is cached at the hypervisor node. The user is notified of a completion of the write access request. The cached data is transmitted to a storage node in the distributed virtual environment, the storage node providing physical storage to the virtual machine.
