MIGRATION PROCESSES UTILIZING MAPPING ENTRY TIMESTAMPS FOR SELECTION OF TARGET LOGICAL STORAGE DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17846242 titled 'MIGRATION PROCESSES UTILIZING MAPPING ENTRY TIMESTAMPS FOR SELECTION OF TARGET LOGICAL STORAGE DEVICES
Simplified Explanation
The patent application describes a method for managing the migration of logical storage devices in a storage system. Here are the key points:
- The method involves maintaining a mapping data structure that associates a unique identifier with each logical storage device in the system.
- Each mapping entry also includes a timestamp associated with the logical storage device.
- When a migration process is initiated, the method identifies the source logical storage device and accesses the mapping data structure to determine its timestamp.
- The method also retrieves the timestamps of one or more candidate target logical storage devices for the migration process.
- Based on the timestamps, the method selects a particular target logical storage device for the migration.
- Finally, the method initiates the migration process to move the source logical storage device to the selected target logical storage device.
Potential applications of this technology:
- Data center management: This method can be used in large-scale data centers to efficiently migrate logical storage devices between different physical storage devices.
- Cloud storage: The method can be applied in cloud storage systems to optimize the allocation of storage resources and improve overall system performance.
- Disaster recovery: By efficiently migrating logical storage devices, this method can help in disaster recovery scenarios by quickly restoring data to alternative storage devices.
Problems solved by this technology:
- Efficient migration: The method provides a systematic approach to select the most suitable target logical storage device for migration based on timestamps, ensuring efficient and effective data transfer.
- Resource optimization: By selecting the target device based on timestamps, the method helps in optimizing the utilization of storage resources in the system.
- Data integrity: The mapping data structure ensures that the logical storage devices are correctly associated with their unique identifiers, preventing any data loss or corruption during the migration process.
Benefits of this technology:
- Improved performance: The method allows for faster and more efficient migration of logical storage devices, leading to improved system performance and reduced downtime.
- Resource efficiency: By selecting the most appropriate target device, the method helps in optimizing the utilization of storage resources, reducing costs and improving overall efficiency.
- Data integrity and reliability: The mapping data structure and timestamp-based selection ensure the integrity and reliability of data during the migration process, minimizing the risk of data loss or corruption.
Original Abstract Submitted
A method comprises maintaining a mapping data structure comprising a plurality of mapping entries, each such mapping entry associating an assigned name of a corresponding logical storage device of a storage system with a unique identifier of that logical storage device, a given such mapping entry further comprising a timestamp associated with the logical storage device. The method further comprises identifying a source logical storage device for a migration process, accessing the mapping data structure to determine a timestamp of the source logical storage device and one or more additional timestamps of one or more respective candidate target logical storage devices for the migration process, selecting based at least in part on the determined timestamps a particular one of the one or more candidate target logical storage devices, and initiating the migration process to migrate the source logical storage device to the selected target logical storage device.
