| 中文摘要 | To satisfy high data availability requirements for cloud storage systems, the data layer of cloud storage systems is regarded as a virtual storage body consists of two virtual storage nodes of a full copy and a encoded copy. A hadoop distributed file system-based complex redundancy scheme integrating the copy redundant mode and coding redundant mode is proposed. Code redundancy is achieved by splitting a data block into several data pieces and using random linear network coding among the pieces. When the storage node availability ranges from 0.6 to 0.9, with the system data availability target of 99.999%, the composite redundancy scheme saves over 35% storage space than full backup scheme. |
