USE OF FLASH CACHE TO IMPROVE TIERED MIGRATION PERFORMANCE |
摘要 |
For data processing in a computing storage environment by a processor device, the computing storage environment incorporating at least high-speed and lower-speed caches, and tiered levels of storage, and at a time in which at least one data segment is to be migrated from one level to another level of the tiered levels of storage, a data migration mechanism is initiated by copying data resident in the lower-speed cache corresponding to the at least one data segment to be migrated to a target on the another level, and reading remaining data, not previously copied from the lower-speed cache, from a source on the one level, and writing the remaining data to the target. |

1. A method for data processing in a computing storage environment, the computing storage environment incorporating at least high-speed and lower-speed caches, and tiered levels of storage, comprising:
at a time in which at least one data segment is to be migrated from one level to another level of the tiered levels of storage, initiating a data migration mechanism by:
copying data resident in the lower-speed cache corresponding to the at least one data segment to be migrated to a target on the another level, andreading remaining data, not previously copied from the lower-speed cache, from a source on the one level, and writing the remaining data to the target. |
