Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The present invention provides a distributed file system storage method based on erasure codes, please refer to figure 1 , in the first embodiment, the erasure code-based distributed file system storage method includes:

[0045] Step S10, obtaining the data to be stored written by the client, and obtaining the verification data corresponding to the data to be stored by means of erasure code encoding;

[0046] The erasure code-based distributed file system storage method provided by the embodiment of the present invention is used for a storage device in a distributed file system to store client data.

[0047] When the client needs to store data, it sends a request to the storage device, and writes the data to be stored into the storage device after being approved. The storage device obtains the data to be stor...

Abstract

The invention discloses a method and device for storing distributed file system based on erasure code, which includes that the pending data written by the client will be obtained. And the Check data corresponding to pending data will be obtained through the encoding mode of the erasure code. The pending data and the check data will be processed separately, and then K copies of the pending data and M copies of the check data will be obtained, whereby K and M are positive integers. K copies of the pending data and M copies of the check data will be stored. The method and device for storing distributed file system based on erasure code also discloses a distributed file system storage device based on erasure code, and reduces the space occupied by the pending data.

Description

technical field [0001] The present invention relates to the technical field of computer Internet, in particular to an erasure code-based distributed file system storage method and device. Background technique [0002] With the continuous development of network technology and information processing technology, the amount of personal data and enterprise data is showing an explosive expansion trend. IT systems are facing the problems of high storage costs, difficult management and low reliability of massive data. In order to make full use of resources , To reduce repeated investment, data storage, as one of the main architecture and infrastructure of IT system, is gradually separated from IT system as a complete system. Due to its characteristics of massive data storage, high scalability, high performance, high reliability, and high availability, the distributed file system is currently being widely discussed and applied in the industry as an enterprise massive data storage sol...
