Abstract

Claims (62)

1. A method for execution by one or more computing devices of a storage network, the method comprises:

receiving a data object for storage in memory of the storage network;

selecting a set of storage nodes of a plurality of sets of storage nodes for dispersed storage of the data object, including:

determining storage attributes associated with each set of storage nodes of the plurality of sets of storage nodes;

determining a storage preference of a user of the storage network associated with the data object; and

comparing the storage preference with the storage attributes; and

in response to determining that the storage preference compares favorably with the storage attributes, facilitating dispersed storage of the data object in the selected set of storage nodes.

2. The method of claim 1 , wherein facilitating dispersed storage of the data object in the selected set of storage nodes includes:

determining dispersed storage error encoding parameters based, at least in part, on the selected set of storage nodes;

encoding the data object in accordance with the dispersed storage error encoding parameters to generate a plurality of encoded data slices; and

forwarding the plurality of encoded data slices to the selected set of storage nodes for storage therein.

3. The method of claim 2 , wherein determining dispersed storage error encoding parameters is further based on a retrieval reliability level associated with the data object.

4. The method of claim 2 , further comprising:

temporarily storing the received data object in a buffer of the storage network, wherein facilitating dispersed storage of the data object in the selected set of storage nodes further includes retrieving the data object from the buffer.

5. The method of claim 1 , wherein the storage attributes associated with each set of storage nodes correspond, at least in part, to a storage reliability level.

6. The method of claim 1 , wherein the storage attributes associated with each set of storage nodes correspond, at least in part, to an input/output bandwidth level.

7. The method of claim 1 , wherein the storage attributes associated with each set of storage nodes correspond, at least in part, to a memory type of a plurality of memory types.

8. The method of claim 1 , wherein the storage preference of a user of the storage network associated with the data object includes at least one of:

a data type of the data object;

a data size of the data object;

a system privilege of an authorized user of the storage network; or

a user group affiliation of an authorized user of the storage network.

9. A computing device comprises:

an interface;

memory that stores operational instructions; and

a processing module operably coupled to the interface and the memory, wherein the processing module is configured to execute the operational instructions to:

receive, via the interface, a data object for dispersed storage in memory of a storage network;

select a set of storage nodes of a plurality of sets of storage nodes for storage of the data object, including:

determining storage attributes associated with each set of storage nodes of the plurality of sets of storage nodes;

determining a storage preference of a user of the storage network associated with the data object; and

comparing the storage preference with the storage attributes; and

in response to determining that the storage preference compares favorably with the storage attributes, facilitate dispersed storage of the data object in the selected set of storage nodes.

10. The computing device of claim 9 , wherein facilitating dispersed storage of the data object in the selected set of storage nodes includes:

determining dispersed storage error encoding parameters based, at least in part, on the selected set of storage nodes;

encoding the data object in accordance with the dispersed storage error encoding parameters to generate a plurality of encoded data slices; and

forwarding the plurality of encoded data slices to the selected set of storage nodes for storage therein.

11. The computing device of claim 10 , wherein determining dispersed storage error encoding parameters is further based on a retrieval reliability level associated with the data object.

12. The computing device of claim 10 , wherein the processing module is further configured to execute the operational instructions to:

temporarily store the received data object in a buffer of the storage network, wherein facilitating dispersed storage of the data object in the selected set of storage nodes further includes retrieving the data object from the buffer.

13. The computing device of claim 9 , wherein the storage attributes associated with each set of storage nodes correspond, at least in part, to a storage reliability level.

14. The computing device of claim 9 , wherein the storage attributes associated with each set of storage nodes correspond, at least in part, to an input/output bandwidth level.

15. The computing device of claim 9 , wherein the storage attributes associated with each set of storage nodes correspond, at least in part, to a memory type of a plurality of memory types.

16. The computing device of claim 9 , wherein the storage preference of the user of the storage network associated with the data object includes at least one of:

a data type of the data object;

a data size of the data object;

a system privilege of an authorized user of the storage network; or

a user group affiliation of an authorized user of the storage network.

17. A non-transitory computer readable storage medium comprises:

at least one memory section that stores operational instructions that, when executed by one or more processing modules of a computing device of a storage network, causes the computing device to:

receive a data object for storage in memory of the storage network;

select a set of storage nodes of a plurality of sets of storage nodes for dispersed storage of the data object, including:

determining storage attributes associated with each set of storage nodes of the plurality of sets of storage nodes;
