SELECTIVE SPACE RECLAMATION OF DATA STORAGE MEMORY EMPLOYING HEAT AND RELOCATION METRICS |
| 摘要 |
Space of a data storage memory of a data storage memory system is reclaimed by determining heat metrics of data stored in the data storage memory; determining relocation metrics related to relocation of the data within the data storage memory; determining utility metrics of the data relating the heat metrics to the relocation metrics for the data; and making the data whose utility metric fails a utility metric threshold, available for space reclamation. |

1. A method for reclaiming space of a data storage memory of a data storage memory system, comprising:
determining heat metrics of data stored in said data storage memory; determining relocation metrics related to relocation of said data within said data storage memory, said relocation metrics comprising a count of the number of times said data has been relocated during reclamation process iterations; determining utility metrics of said data relating said heat metrics to said relocation metrics for said data; and making said data whose utility metric fails a utility metric threshold, available for space reclamation. |
