US 2016/0259802 A1 · ADAPTIVE DATA STRIPING AND REPLICATION ACROSS MULTIPLE STORAGE CLOUDS FOR HIGH AVAILABILITY AND PERFORMANCE

Abstract

Technologies for adaptively striping data across multiple storage clouds include receiving user constraints corresponding one or more cloud storage providers, receiving a file to be striped across the cloud storage providers, splitting the received file into file blocks, allocating each of the file blocks to a different one of the cloud storage providers as a function of the user constraints and operating conditions of each of the cloud storage providers, and sending each of the file blocks to the cloud storage provider to which each file block is allocated. In some embodiments, file blocks may be re-allocated from one cloud storage provider to another cloud storage provider as a function of changing user constraints or operating conditions. In addition, each of the file blocks may be retrieved from the cloud storage providers to re-assemble the file.

Claims25

Dependent claims

A computing device for re-assembling a file from a plurality of file blocks striped across a plurality of storage clouds, the computing device comprising:

a block location determination module to (i) determine that a first cloud storage provider of a plurality of cloud storage providers is storing a first file block of a particular file to be re-assembled, and (ii) determine that a second cloud storage provider of a plurality of cloud storage providers is storing a second file block of the particular file to be re-assembled;
a file re-assembly module to (i) request the first file block from the first cloud storage provider, and (ii) request the second file block from the second cloud storage provider;
and
a communication module to (i) receive the first file block from the first cloud storage provider, and (ii) receive the second file block from the second cloud storage provider,
wherein the file re-assembly module is further to re-assemble the particular file to be re-assembled from the received first and second file blocks.

A method for re-assembling a file from a plurality of file blocks striped across a plurality of storage clouds by a computing device, the method comprising:

determining, by the computing device, that a first cloud storage provider of a plurality of cloud storage providers is storing a first file block of a particular file to be re-assembled;
determining, by the computing device, that a second cloud storage provider of a plurality of cloud storage providers is storing a second file block of the particular file to be re-assembled;
requesting, by the computing device, the first file block from the first cloud storage provider;
requesting, by the computing device, the second file block from the second cloud storage provider;
receiving, by the computing device, the first file block from the first cloud storage provider;
receiving, by the computing device, the second file block from the second cloud storage provider;
and
re-assembling, by the computing device, the particular file to be re-assembled from the received first and second file blocks.

5 more elements

One or more machine readable media comprising a plurality of instructions stored thereon that in response to being executed result in a computing device:

determining, by the computing device, that a first cloud storage provider of a plurality of cloud storage providers is storing a first file block of a particular file to be re-assembled;
determining, by the computing device, that a second cloud storage provider of a plurality of cloud storage providers is storing a second file block of the particular file to be re-assembled;
requesting, the first file block from the first cloud storage provider;
requesting the second file block from the second cloud storage provider;
receiving the first file block from the first cloud storage provider;
receiving the second file block from the second cloud storage provider;
and
re-assembling the particular file to be re-assembled from the received first and second file blocks.
