Abstract:
Scaling-in of a geographically diverse data storage system is disclosed. Data chunks stored in storage devices of different zones can be convolved to conserve memory. The zone storage system can be a geographically diverse storage system. Removing a zone from the geographically diverse data storage system can risk data loss without adequate replication of data from the zone to be removed. The zone to be removed can be placed in a ‘read-only’ state. Data chunks form the zone to be removed can be duplicated at other zones of the geographically diverse data storage system. A data chunk comprising convolved representations of data is duplicated to a zone in a manner that results in loss of geographical diversity, a corresponding chunk can be duplicated at another zone to restore geographical diversity. Validation of data can be performed prior to removal of a zone in a scaling-in event.

Claim (Index 12):
A method, comprising:\n determining, by a system comprising a processor, that a first data zone is to be removed from a distributed storage construct wherein the distributed storage construct comprises a first data zone comprising a first data chunk, a second data zone comprising a second data chunk, and a third data zone, wherein the first data zone, the second data zone, and the third data zone are different data zones, wherein the first data chunk is represented in a first combined data chunk that is stored in the second data zone, wherein the first combined data chunk is a combination of the first data chunk and first other data chunks, and wherein the first other data chunks comprise first data chunks from each of the data zones other than the first data zone and other than the second data zone; in response to the determining, by the system, that the first data zone is to be removed from the distributed storage construct and prior to removing the first data zone from the distributed storage construct, replicating a second combined data chunk stored at the first data zone into the second data zone, wherein the second combined data chunk is a combination of the second data chunk and second other data chunks, and wherein the second other data chunks comprise second data chunks from each of the data zones other than the first data zone; replicating, by the system, the first data chunk to the second data zone, resulting in a primary first data chunk copy, and the first data chunk to the third data zone, resulting in a secondary first data chunk copy; in response to extracting, by the system, the first data chunk from the first combined data chunk, resulting in a modified first combined data chunk stored at the second data zone, removing the first data zone from the distributed storage construct; extracting, by the system, from the second combined data chunk the second data chunk stored on the second data zone, resulting in a modified second combined data chunk; and replicating, by the system, the second data chunk into another data zone of the data zones other than the first data zone and other than the second data zone, resulting in a secondary second data chunk copy on the other data zone.
