This project aims to improve the performance of distributed data storage systems during the recovery of node-failures using advanced repair techniques for the underlying erasure coding schemes. Reed-Solomon codes, employed in most of current storage systems, for example Google Colossus, Baidu's Atlas, Yahoo Object Store, and Facebook's f4, require extremely high network bandwidth and disk I/O for failure recovery. Expected outcomes of this project include significantly improved repair schemes for Reed-Solomon codes with respect to the network bandwidth and disk I/O. The project will benefit data storage service providers, governments, businesses, hospitals, and schools.

本计画的目的是利用先进的修复技术来改善分散式资料储存系统在节点失效时的效能。Reed-Solomon码在当前大多数存储系统中使用，例如Google Colossus，百度的Atlas，Yahoo Object Store和Facebook的f4，需要极高的网络带宽和磁盘I/O来进行故障恢复。该项目的预期成果包括在网络带宽和磁盘I/O方面大大改进Reed-Solomon码的修复方案。该项目将使数据存储服务提供商、政府、企业、医院和学校受益。
