Abstract: A processor may identify that an external power source has begun powering a computing device. The processor may identify computational data in a volatile memory of the computing device. The processor may determine that the external power source does not have sufficient energy capacity to provide the computing device enough power to process the computational data at a first I/O throttling rate. The processor may increase the first I/O throttling rate to a second I/O throttling rate. The second I/O throttling rate may allow the computational data to be processed by the computing device with the energy capacity of the external power source.

Moreover, in response to a determination to transfer at least one of the identified portions of the actual data to the second tier, one or more instructions are sent to transfer the at least one of the identified portions of the actual data from the first tier to the second tier.

Abstract: A data storage system has multiple tiers of data storage including an upper tier having a lower access latency and a lower tier having a higher access latency. A storage controller of the data storage system receives, via an interface, an access request of a workload for a target file system object, where the target file system object has an associated temperature. In response to the access request for the target file system object, the storage controller accesses the target file system object in the data storage and conditions update of the associated temperature of the target file system object based on at least one of a set including the interface and the workload. The storage controller distributes a collection of file system objects including the target file system object among the multiple tiers based on respective heats of file system objects in the collection.

Copies of the data object may be stored on a plurality of storage nodes located in first and second geographic locations. A first processing activity for a storage node that corresponds with the application category of the data object may be determined. A first storage node may be selected for a first update based on being associated with the first processing activity in a first proportion. The copy of the data object stored at the first storage node may be updated before updating a copy of the data object stored at a second storage node. The second storage node may be associated with the first processing activity in a second proportion, with the second proportion being less than the first proportion.

Abstract: A computing environment includes a home site and a cache site with nonhomogeneous thin-provisioned storage configurations. A file management system updates files stored at the cache site. Each updated file has an updated file size and a pre-update file size. When a resynchronization is needed between the cache site and the home site, for example due to an extended communication failure, the storage requirement changes for the updated files are calculated and a notification is sent to the home site. The notification identifies the updated files and the storage requirement changes. The home site sends a reply to the cache site. The reply identifies which files are approved for immediate processing. The cache site transfers resynchronization data for the approved files to the home site, and delays transferring resynchronization data for the unapproved files until subsequent replies from the home site indicate that the previously unapproved files are now approved.
