Abstract

Geological allocation of storage space for a zone of a geographically diverse storage system is disclosed. A first allocation of storage space of the first zone can be adapted. In some embodiments, the adaptation can result in changes to a size of a storage area for a type of data stored in the first zone. In some embodiments, the adaptation can result in changes to a location of a storage area for a type of data stored in the first zone. In an aspect, the adaptation can result in improved inter-zone network utilization. In another aspect, the adaptation can result in efficient use of storage space in view of the amount and type of data to be stored in the zone. In an embodiment, the types of data stored can comprise a buffer space, local data, remote data, and combined or convolved data.

Claims

1. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

receiving a first storage allocation corresponding to storage of data in a first zone of a geographically diverse data storage system;

determining adaptation information based on the first storage allocation being determined to satisfy a rule related to allocation of storage space; and

initiating a change to the storage of data based on the adaptation information.

2. The system of claim 1, wherein the first zone is a different zone than a second zone of the geographically diverse storage system, and wherein the first zone stores, on a first storage component, first information in a first data chunk to replicate second information represented in a second data chunk stored on a second storage component of the second zone.

3. The system of claim 2, wherein the first data chunk is a first convolved data chunk, and wherein the first convolved data chunk convolves the first information with third information represented in a third data chunk.

4. The system of claim 3, wherein the third data chunk is stored on the second storage component of the second zone of the geographically diverse data storage system.

5. The system of claim 3, wherein the third data chunk is stored on a third storage component of a third zone of the geographically diverse data storage system.

6. The system of claim 3, wherein the first convolved data chunk convolves the first information with the third information represented in the third data chunk results via an XOR operation.

7. The system of claim 1, wherein the determining adaptation information is further based on a first amount of a first type of a first portion of the data and a second amount of a second type of a second portion of the data.

8. The system of claim 7, wherein the determining adaptation information is further based on a determined data pressure value representing a correlation between the first amount, the second amount, and a total amount of storage for the first zone of the geographically diverse data storage system.

9. The system of claim 1, wherein the determining adaptation information is further based on an amount of inter-zone network usage between the first zone and at least a second zone of the geographically diverse data storage system.

10. The system of claim 1, wherein the determining adaptation information is further based on an amount of intra-zone network usage between a first data store of the first zone and a second data store of the first zone.

11. A method, comprising:

in response to receiving first information indicating a first storage allocation of first data in a first zone of a geographically diverse data storage system, generating, by a system comprising a processor and a memory, change information based on a first amount of a first type of a first portion of the first data and a second amount of a second type of a second portion of the first data; and

triggering, by the system, a change to the first storage allocation of the first data in the first zone based on the change information.

12. The method of claim 11, wherein the generating the change information is further based on a correlation between the first amount, the second amount, and a total amount of storage for the first zone of the geographically diverse data storage system.

13. The method of claim 11, wherein the generating the change information is further based on an amount of inter-zone network traffic between the first zone and at least a second zone of the geographically diverse data storage system.

14. The method of claim 11, wherein the generating the change information is further based on an amount of intra-zone network usage between a first data store of the first zone and a second data store of the first zone.

15. The method of claim 11, wherein the generating the change information corresponds to causing a first resizing a first storage area for local data chunks, a second resizing of a second storage area for combined data chunks, and a third resizing of a third storage area for another type of data chunk.

16. The method of claim 15, wherein the resizing of the second storage area for combined data chunks enables storage of a convolved chunk, and wherein a convolution of chunks resulting in the convolved chunk is accomplished via an XOR procedure.

17. The method of claim 11, wherein the change information is first change information, wherein the change is a first change, and further comprising in response to receiving second information indicating a third storage allocation of second data in a third zone of the geographically diverse data storage system, generating, by the system, second change information based on a third amount of the first type of a third portion of the second data and a fourth amount of the second type of a fourth portion of the second data;

and

triggering, by the system, a second change to the second storage allocation of the second data in the second zone based on the second change information.

18. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

determining an adaptation of a storage allocation state corresponding to storage of data across one or more data stores of a first zone of a geographically diverse storage system, wherein the geographically diverse storage system further comprises at least a second zone and a third zone that are different than the first zone, and wherein the adaptation is based on an amount of a first type of a first portion of the data and an amount of a second type of a second portion of the data; and

communicating information to a device of the first zone, resulting in initiation of the adaptation of the storage allocation state.

19. The machine-readable storage medium of claim 18, wherein the first type of the first portion of the data is a combined data chunk type and the first portion of the data comprises a combined data chunk comprising information that is duplicative of a first data chunk stored on the second zone and a third data chunk stored on the third zone.

20. The machine-readable storage medium of claim 19, wherein the combined data chunk is a result of performing an XOR procedure based on a replica of the first data chunk stored at the first zone and a replica of the third data chunk stored at the first zone.
