Independent Virtual Disk Management via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical virtual disks are dependent on virtual machines and cannot exist independently, making it difficult to manage them without manual operations and are not easily transferable or shareable between machines.
Innovation Solution
An independent virtual disk is created with a unique identifier that survives the destruction of a virtual machine, allowing it to be detached, stored, and reattached to other machines, and can be managed independently using a cloud environment with tools like virtual infrastructure management systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a virtual disk is created dependent on a virtual machine, then the virtual disk can be managed through the virtual machine lifecycle, but the virtual disk cannot exist independently and is destroyed when the virtual machine is destroyed
Solution Approach 1:
The patent separates the virtual disk from the virtual machine lifecycle by introducing an independent virtual disk entity that can exist separately. The virtual disk is no longer bound to a specific virtual machine, allowing it to be preserved, transferred, or shared independently while maintaining its integrity and manageability through the system.
Solution Approach 2:
The patent introduces a virtual disk manager as an intermediary component that handles virtual disk operations independently of virtual machine management. This mediator enables the virtual disk to be managed separately, facilitating independent creation, preservation, attachment, and detachment operations without requiring virtual machine involvement.
2Ease of operation
If virtual disk management is integrated with virtual machine management, then operations can be simplified through unified control, but individual virtual disk management requires burdensome manual operations
Solution Approach 1:
The patent enables virtual disks to be self-managed through the virtual disk manager, which handles creation, preservation, and attachment operations autonomously. Users can perform individual virtual disk operations without manual intervention or complex procedures, as the system automatically manages the lifecycle and state of independent virtual disks.
Solution Approach 2:
The virtual disk manager provides universal management capabilities that work across different virtual machines and scenarios. The same management interface and operations can be applied to any virtual disk regardless of its current attachment state, enabling consistent and efficient management across the entire virtualized environment.
3Adaptability or versatility
If a virtual disk is tied to a specific virtual machine, then the virtual machine can access the virtual disk directly, but the virtual disk cannot be transferred or shared between machines easily
Solution Approach 1:
The patent creates an independent copy or representation of the virtual disk that is detached from the original virtual machine context. This independent virtual disk maintains all data and characteristics while being able to be attached to different virtual machines, enabling easy transfer and sharing without losing the original virtual disk or its identity.
Solution Approach 2:
The patent introduces a new dimension of virtual disk existence by separating it from the virtual machine hierarchy. The virtual disk operates in an independent dimension where it can be attached to multiple virtual machines across different contexts, enabling flexible transferability and sharing while maintaining its core identity and data integrity.

AI summary
A computer-implemented method for managing an independent virtual disk. The method includes creating an independent virtual disk; in response to the creating the independent virtual disk, creating a first virtual machine; and attaching an independent virtual disk to the first virtual machine; and managing the independent virtual disk by controlling the first virtual machine that is attached to the independent virtual disk.
