Abstract

Techniques are described for distributed storage and retrieval of data by a defined computing system that includes a plurality of computing devices arranged in a network topology. The computing system stores two or more data blocks of a data set across two or more computing devices of the computing system. Each data block comprises at least one fragment of the data set and metadata including a data set identifier. The storage locations of the data blocks are determined based on messages exchanged among the plurality of computing devices, and may only be known by the computing devices within the computing system. After receipt of a request to access the data set, the two or more computing devices retrieve the two or more data blocks based on the data set identifier, and the computing system sends the two or more data blocks to a requesting device external to the computing system.

Dependent claims

A method comprising:

determining two or more computing devices of a plurality of computing devices in which to store two or more data blocks of a data set based on messages exchanged among the plurality of computing devices, wherein the plurality of computing devices are interconnected in a network topology, and wherein each data block of the two or more data blocks comprises at least one fragment of two or more fragments of the data set and metadata including a data set identifier and instructions for reassembling the data set from the two or more data blocks;
storing, by a first computing device of the two or more computing devices, a first data block of the two or more data blocks at a first storage location in a data store of the first computing device;
storing, by a second computing device of the two or more computing devices, a second data block of the two or more data blocks at a second storage location in a data store of the second computing device, wherein the first and second storage locations of the two or more data blocks are known only by the plurality of computing devices in the network topology and are unknown to devices external to the network topology, and wherein the first and second storage locations of the two or more data blocks are not maintained in a centralized manner;
based on receipt of a request to access the data set including the data set identifier from a requesting device external to the network topology:
retrieving, by the first computing device of the two or more computing devices, the first data block from the first storage location in the data store of the first computing device based on the data set identifier, and
retrieving, by the second computing device of the two or more computing devices, the second data block from the second storage location in the data store of the second computing device based on the data set identifier;
and
sending, by the two or more computing devices, the two or more data blocks of the data set to the requesting device external to the network topology.

5 more elements

A computing system comprising a plurality of computing devices interconnected in a network topology, wherein the plurality of computing devices is configured to:

determine two or more computing devices of the plurality of computing devices in which to store two or more data blocks of a data set based on messages exchanged among the plurality of computing devices, wherein each data block of the two or more data blocks comprises at least one fragment of two or more fragments of the data set and metadata including a data set identifier and instructions for reassembling the data set from the two or more data blocks;
wherein the two or more computing devices include:
a first computing device configured to store a first data block of the two or more data blocks at a first storage location in a data store of the first computing device, and
a second computing device configured to store a second data block of the two or more data blocks at a second storage location in a data store of the second computing device, wherein the first and second storage locations of the two or more data blocks are known only by the plurality of computing devices in the network topology and are unknown to devices external to the network topology, and wherein the first and second storage locations of the two or more data blocks are not maintained in a centralized manner;
receive of a request to access the data set including the data set identifier from a requesting device external to the network topology, wherein based on the request:
the first computing device is configured to retrieve the first data block from the first storage location in the data store of the first computing device based on the data set identifier, and
the second computing device is configured to retrieve the second data block from the second storage location in the data store of the second computing device based on the data set identifier;
and
send, by the two or more computing devices, the two or more data blocks of the data set to the requesting device external to the network topology.

6 more elements

Non-transitory computer-readable media comprising instructions that, when executed, cause processing circuitry of a plurality of computing devices to:

determine two or more computing devices of the plurality of computing devices in which to store two or more data blocks of a data set based on messages exchanged among the plurality of computing devices, wherein the plurality of computing devices are interconnected in a network topology, and wherein each data block of the two or more data blocks comprises at least one fragment of two or more fragments of the data set and metadata including a data set identifier and instructions for reassembling the data set from the two or more data blocks;
store, by a first computing device of the two or more computing devices, a first data block of the two or more data blocks at a first storage location in a data store of the first computing device;
store, by a second computing device of the two or more computing devices, a second data block of the two or more data blocks at a second storage location in a data store of the second computing device, wherein the first and second storage locations of the two or more data blocks are known only by the plurality of computing devices in the network topology and are unknown to devices external to the network topology, and wherein the first and second storage locations of the two or more data blocks are not maintained in a centralized manner;
based on receipt of a request to access the data set including the data set identifier from a requesting device external to the network topology:
retrieve, by the first each computing device of the two or more computing devices, the first data block from the first storage location in the data store of the first computing device based on the data set identifier, and
retrieve, by the second computing device of the two or more computing devices, the second data block from the second storage location in the data store of the second computing device based on the data set identifier;
and
send, by the two or more computing devices the two or more data blocks of the data set to the requesting device external to the network topology.
