摘要:
Embodiments of the invention relate to co-migration in a shared pool of resources with similarity across data sets of a migrating application. The data sets are processed and profiled. Metadata is reviewed to remove duplicate elements and to distribute the processing load across available nodes. At the same time, a ranking may be assigned to select metadata to support a prioritized migration. Non-duplicate data chunks are migrated across the shared pool of resources responsive to the assigned prioritization.

A method, system, and article are provided to enable a Hyperswap operation in a clustered computer system. Each node in the system is configured with flash memory, with a hierarchical list of boot volumes therein. Following a Hyperswap operation, the current boot volume is communicated to each node in the cluster and each node joining the cluster. All previously inactive nodes that were booted from the improper boot volume are re-booted from the correct and the flash memory is amended to reflect the correct boot volume.

The invention provides a method, apparatus and system for reducing power consumption involving data storage devices. One embodiment involves storing data in a first memory; in response to the first memory exceeding a first threshold, migrating the data from the first memory to a second memory; in response to the second memory exceeding a second threshold, then activating a third memory if the third memory is in active; and in response to the second memory exceeding a third threshold greater than the second threshold, migrating the data from the second memory to a third memory; wherein the second memory is sized and configured to store data targeted for the third memory to intelligently maintain a portion of the third memory in an inactive state.
