I/O STATISTIC BASED DEPOPULATION OF STORAGE RANKS |
| 摘要 |
The method includes identifying, by one or more computer processors, at least one source rank selected for depopulation in a storage pool. The method further includes identifying, by one or more computer processors, one or more source extents for depopulation, wherein the identified one or more source extents belongs to the identified at least one source rank selected for depopulation. The method further includes obtaining, by one or more computer processors, for each identified source extent of the identified one or more source extents to be depopulated, at least one I/O workload. The method further includes sorting, by one or more computer processors, the one or more source extents to be depopulated, based at least in part on the at least one I/O workload for each identified source extent of the identified one or more source extents. |

1. A method for depopulation of storage ranks, the method comprising:
identifying, by one or more computer processors, at least one source rank selected for depopulation in a storage pool; identifying, by one or more computer processors, one or more source extents for depopulation, wherein the identified one or more source extents belongs to the identified at least one source rank selected for depopulation; obtaining, by one or more computer processors, for each identified source extent of the identified one or more source extents to be depopulated, at least one I/O workload; and sorting, by one or more computer processors, the one or more source extents to be depopulated, based at least in part on the at least one I/O workload for each identified source extent of the identified one or more source extents. |
