USE OF DIFFERING GRANULARITY HEAT MAPS FOR CACHING AND MIGRATION |
| 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, groups of data segments are migrated between the tiered levels of storage such that if a selected group is cached in the lower-speed cache and is determined to become uniformly hot, migrating the selected group from the lower-speed cache to the SSD portion while refraining from processing data retained in the lower-speed cache until the selected group is fully migrated to the SSD portion. |

1. A method 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, the method comprising:
migrating groups of data segments between the tiered levels of storage; wherein if a selected group is cached in the lower-speed cache and is determined to become uniformly hot, migrating the selected group from the lower-speed cache to the SSD portion while refraining from processing data retained in the lower-speed cache until the selected group is fully migrated to the SSD portion. |
