METHOD, DEVICE, AND COMPUTER PROGRAM PRODUCT FOR MIGRATING DATA - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240134536 titled 'METHOD, DEVICE, AND COMPUTER PROGRAM PRODUCT FOR MIGRATING DATA
Simplified Explanation
The patent application describes a method for migrating data in response to the detection of a failed group in a drive of groups. If the total number of failed groups in the drive is below a predetermined threshold, data from the failed group is migrated to a reserved group in a reserved space of the drive. Read/write requests to the failed group are then redirected to the reserved group based on a mapping relationship.
- Explanation of the patent/innovation:
- Data migration in response to a failed group in a drive of groups - Determination of total failed groups below a predetermined threshold - Migration of data to a reserved group in the drive - Redirecting read/write requests to the reserved group based on mapping relationship
- Potential applications of this technology:
- Data storage systems - Data recovery systems - Fault-tolerant storage solutions
- Problems solved by this technology:
- Preventing the need to repair an entire drive due to one failed write request - Avoiding the replacement of the drive - Saving resources, time, and labor - Improving the performance of a storage system
- Benefits of this technology:
- Efficient data migration in case of drive failures - Enhanced fault tolerance in storage systems - Cost-effective solution for data recovery
- Potential commercial applications of this technology:
- Data storage companies - Cloud storage providers - Data center solutions providers
- Possible prior art:
- Prior art related to data migration in storage systems - Prior art on fault-tolerant storage solutions
- Unanswered Questions:
- How does the mapping relationship between the failed group and the reserved group work?
- Unanswered Questions:
The patent application does not provide detailed information on the specific mechanism of the mapping relationship between the failed group and the reserved group. Further clarification on this aspect would be beneficial for understanding the implementation of the technology.
- What are the specific criteria for determining the predetermined threshold of failed groups in the drive?
The patent application mentions a predetermined threshold for the total number of failed groups in the drive, but it does not elaborate on the specific criteria used to set this threshold. More information on how this threshold is determined would provide insights into the decision-making process of the technology.
Original Abstract Submitted
data is migrated. for instance, in response to detection of a failed group in a drive of groups comprising respective blocks, it is determined whether the total number of groups in the drive that have failed is less than a predetermined threshold. data associated with the failed group is migrated to a reserved group in a reserved space of the drive according to a determination that the total number is less than the predetermined threshold; and a read/write (i/o) request to the failed group is redirected to the reserved group based on a mapping relationship from the failed group to the reserved group. consequently, data does not need to be repaired on an entire drive due to one failed write request and replacing the drive is avoided, thereby saving resources, time and labor, and improving the impact of the failed write request on the performance of a storage system.
