Abstract
The present application relates to a kind of data reliable storage methods based on erasure code adaptive coding, the application is saved by being encoded as erasure code to data, and under different workloads, different coding strategies are converted, so that the storage system can adapt to different working environment, maintain the reliability of data.The present application is composed of two components of improved erasure code and adaptive coding, improved erasure code is improved based on existing erasure code, the performance of existing erasure code is enhanced by the XOR grouping coding XGC proposed in the present application, to provide the basis for adaptive coding.Component two judges work load and changes coding strategy based on the hot and cold characteristics of data and the use rate of storage system.
