REDISTRIBUTION OF DISKS BASED ON DISK WEAR PATTERNS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240126451 titled 'REDISTRIBUTION OF DISKS BASED ON DISK WEAR PATTERNS

Simplified Explanation

Redistributing disks based on disk wear patterns is disclosed in this patent application. The wear patterns of disk drives in a storage system are learned or determined. When a restore operation is performed, the volumes to disk drive mappings are changed to balance the overall wear pattern of the storage system. This ensures that, after the restore operation, disks that had comparatively lower wear levels are used more heavily while disks that had comparatively higher wear levels are used less heavily.

• Explanation:

- Learn or determine wear patterns of disk drives - Change volume to disk drive mappings during restore operation to balance wear patterns - Ensure disks with lower wear levels are used more heavily post-restore - Ensure disks with higher wear levels are used less heavily post-restore

• • Potential Applications:

- Data centers - Cloud storage providers - Enterprise storage solutions

• • Problems Solved:

- Uneven wear on disk drives - Maximizing disk lifespan - Improving overall storage system performance

• • Benefits:

- Prolonged disk drive lifespan - Enhanced storage system reliability - Optimal disk usage distribution

• • Potential Commercial Applications:

- Storage system manufacturers - Data center operators - Cloud storage providers

• • Possible Prior Art:

- Disk wear leveling algorithms in storage systems

• • Unanswered Questions:

1. How does the patent application determine the wear patterns of disk drives? - The patent application does not provide specific details on the method used to learn or determine the wear patterns of disk drives. 2. What impact does redistributing disks based on wear patterns have on overall storage system performance? - The patent application does not elaborate on the potential performance improvements resulting from balancing disk wear patterns.

Original Abstract Submitted

redistributing disks based on disk wear patterns is disclosed. the wear patterns of disk drives in a storage system are learned or determined. when a restore operation is performed, the volumes to disk drive mappings are changed to balance the overall wear pattern of the storage system. this insures that, after the restore operation, disks that had comparatively lower wear levels are used more heavily while disks that had comparatively higher wear levels are used less heavily.
