Report Errors
A parity management scheme called Erasure Coding is widely used in cloud storage and data centers to increase the stability of stored data. Erasure Coding provides high stability and space efficiency compared to the other data parity management system, however, it still takes a lot of computation time due to data encoding and decoding overhead. In addition, data cannot be recovered when a data error of more than the number of parity blocks occurs. In this paper, the data encoding efficiency is improved by mixing the erasure coding and compression. In the proposed method, the error can be recovered even if a data error greater than the number of parity blocks occurs. The compression is added to SimEDC, which is an erasure coding simulation tool developed for data center. When the compression technique was mixed with the erasure coding, it was confirmed that the data recovery performance was improved compared to the existing one.
