Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent obsolescence of server hardware necessitates frequent and time-consuming physical migrations of data and operating systems, which can be error-prone and inefficient, especially for users with multiple servers.
Innovation Solution
A method and apparatus for migrating a physical server to a virtual server, where the data and operating system are copied to replacement storage and converted into a virtual server image, allowing the virtual server to run on generic hardware, enabling seamless hardware upgrades and reducing the need for frequent physical migrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical server migration is performed frequently due to hardware obsolescence, then server functionality can be maintained on new hardware, but the migration process becomes time-consuming and error-prone
Solution Approach 1:
The patent creates a virtual copy (virtual machine image) of the physical server's operating system and data, which can be deployed to new hardware without physical migration. This copying approach allows seamless transition to new hardware while maintaining server functionality, eliminating the time-consuming process of physical data transfer and system reconfiguration.
Solution Approach 2:
The patent introduces a storage management device as an intermediary that facilitates the migration process. This device coordinates between the source and destination systems, managing the creation and deployment of virtual machine images, thereby reducing migration complexity and time while ensuring functionality continuity.
2Reliability
If physical server migration is performed manually, then server data can be transferred to new hardware, but the process becomes mistake-laden and complex
Solution Approach 1:
The patent implements automated self-service mechanisms where the storage management device automatically creates virtual machine images, allocates storage resources, and deploys systems without manual intervention. This automation eliminates human errors associated with manual migration while simplifying the overall process complexity through centralized automated management.
Solution Approach 2:
The patent incorporates feedback mechanisms where the storage management device monitors the migration process, tracks data transfer status, and automatically adjusts parameters to ensure accurate data transfer. This feedback loop ensures data integrity while reducing process complexity through automated error detection and correction.
3Adaptability or versatility
If storage capacity changes during physical migration, then new hardware requirements can be met, but storage characteristics are lost
Solution Approach 1:
The patent creates a universal virtual machine image that can be deployed across different hardware platforms with varying storage capacities. The virtualization layer abstracts the underlying storage characteristics, allowing the same virtual server image to adapt to different hardware configurations while maintaining consistent functional behavior and data integrity.
Solution Approach 2:
The patent dynamically adjusts storage parameters during the virtualization process, transforming physical storage characteristics into virtual storage allocations. This parameter transformation allows the system to adapt to new hardware storage capacities while preserving the logical storage characteristics and data access patterns that the server application expects.
Data Source
AI summary
According to an embodiment of the invention, a physical server is migrated to a virtual server, which may then be adopted by a new physical server. When the physical server is migrated, the physical server contacts a multi-appliance management application to determine a location on a storage network for replacement storage. The physical server copies its data volumes to the replacement storage. The migration process also converts the operating system of the physical server into a virtual server. The virtual server is a software incarnation of the physical server, and can be run using a generic hardware server. The data of the physical server stored in the replacement storage is linked to the virtual server. In this way, a physical server is migrated to a virtual server.
