Network disk aggregation method based on IDA algorithm

Abstract

The invention provides a network disk aggregation method based on IDA algorithm, includes two steps: upload and download. The method comprises the following steps: the user data files uploaded to thenetwork disk aggregation cloud server are sliced by the IDA algorithm; the network disk aggregation cloud server creates sliced replicas for each data slice; the data slices carrying redundant information are sent to each network disk with higher QoS level; the user data files are uploaded to the network disk aggregation cloud server. Download steps: the disk aggregation client sends a file read request to the disk aggregation cloud server, The disk aggregation cloud server reads the storage location of each data slice according to the file reading request, extracts the data slice from each disk according to the storage location, and then restores the extracted data slice into the user data file by using the IDA algorithm, and sends the data slice back to the disk aggregation client. The network disk aggregation method is conducive to improving the usability and security of user data stored on the network disk, to improving the QoS of the network disk, and to improving the reliabilityof the use of the network disk.

Description

technical field [0001] The invention belongs to the field of computer information management technology, and in particular relates to an IDA algorithm-based network disk aggregation method. Background technique [0002] Cloud storage, developed from cloud computing, is a computer system that allocates network storage resources to users on demand. Cloud storage service providers use this real-time, on-demand allocation of network storage resources to charge. At present, network disk products, as a typical representative of the concept of cloud storage, are welcomed by more and more users due to their advantages of openness, high efficiency, and low price. However, users are increasingly concerned about the privacy, integrity and controlled sharing of their data stored in the cloud. The fact that cloud service providers such as Google, MediaMax and Salesforce.com have leaked or lost user data in recent years has confirmed people's fears. There are various types of network di...
