Many large-scale distributed storage systems deploy erasure coding to protect data from frequent server failures for cost reason. In most of these systems, newly inserted data is first replicated across different storage servers and then migrated to erasure coded. Although this offline encoding manner can improve data access before data is erasure coded for some storage systems, it helps little and...
Distributed storage systems usually adopt erasure codes to ensure the data reliability due to the better space efficiency and higher reliability. However, existing data insertion schemes for erasure codes are not appropriate for the continuous online data due to bottleneck of the centralized insertion schemes and the low efficiency of the decentralized insertion schemes. In this paper, we propose...
