Abstract

A computer program product, according to one embodiment, includes a computer readable storage medium having program instructions embodied therewith. The computer readable storage medium is not a transitory signal per se. Moreover, the program instructions readable and/or executable by a processor to cause the processor to perform a method which includes: maintaining a heat map monitoring table on a per volume basis for a plurality of volumes which includes a heat count for each data block in the respective volume. A request to delete a first volume is received, and the data blocks in the first volume are depended on by one or more other volumes of the plurality of volumes are identified. The identified data blocks and corresponding heat counts are copied to the respective one or more other volumes, and a list which includes the identified data blocks and corresponding heat counts are sent to a controller.

Dependent claims

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions readable and/or executable by a processor to cause the processor to perform a method comprising:

maintaining, by the processor, a heat map monitoring table on a per volume basis for a plurality of volumes in a multi-tier data storage architecture, wherein the heat map monitoring table includes a heat count for each data block in the respective volume;
receiving, by the processor, a request to delete a first volume of the plurality of volumes;
identifying, by the processor, which data blocks in the first volume are depended on by one or more other volumes of the plurality of volumes;
copying, by the processor, the identified data blocks and the corresponding heat counts to the respective one or more other volumes;
and
sending, by the processor, a list which includes the identified data blocks and the corresponding heat counts to a controller.

3 more elements

A computer-implemented method, comprising:

receiving a list of data blocks included in a volume and identified as being depended on by one or more other volumes,
wherein the list includes a heat count corresponding to each of the identified data blocks in the list,
wherein the heat counts correspond to a heat map monitoring table;
and
using heat counts corresponding to the identified data blocks to determine a tier in a multi-tier data storage architecture on which to store each of the identified data blocks.

2 more elements

receiving, by the processor, a list of data blocks included in a volume and identified as being depended on by one or more other volumes;
wherein the list includes a heat count corresponding to each of the identified data blocks in the list,
wherein the heat counts correspond to a heat map monitoring table;
and
using, by the processor, heat counts corresponding to the identified data blocks to determine a tier in a multi-tier data storage architecture on which to store each of the identified data blocks.
