WEAR LEVELING BETWEEN STORAGE DEVICES OF A STORAGE SYSTEM BASED ON INPUT/OUTPUT PATTERNS OF STORAGE OBJECTS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17743860 Titled 'WEAR LEVELING BETWEEN STORAGE DEVICES OF A STORAGE SYSTEM BASED ON INPUT/OUTPUT PATTERNS OF STORAGE OBJECTS'
Simplified Explanation
The abstract describes an apparatus that monitors input/output operations for storage objects on storage devices in a storage system. It identifies patterns in these operations that affect the wear level of the storage devices and determines the wear status of each device. Based on this information, the apparatus selects certain storage objects to be moved from one device to another in order to balance the wear levels across the system.
Original Abstract Submitted
An apparatus comprises a processing device configured to monitor input/output (IO) operations for storage objects stored on storage devices of a storage system for a designated period of time, to identify IO patterns associated with the storage objects, wherein the IO patterns are associated with different wear level impacts on the storage devices of the storage system, and to determine a wear status of each storage device of the storage system. The processing device is also configured to select one or more storage objects to move from a first to a second storage device of the storage system based at least in part on the monitored input/output operations, the identified IO patterns, and the determined wear status of each storage device. The processing device is further configured to move the selected storage objects from the first to the second storage device to perform wear level balancing for the storage system.
