A Hierarchical RAID Architecture Towards Fast Recovery and High Reliability.
IEEE Transactions on Parallel and Distributed Systems(2018)
摘要
Disk failures are very common in modern storage systems due to the large number of inexpensive disks. As a result, it takes a long time to recover a failed disk due to its large capacity and limited I/O. To speed up the recovery process and maintain a high system reliability, we propose a hierarchical code architecture with erasure codes, OI-RAID, which consists of two layers of codes, outer layer...
