OI-RAID: A Two-Layer RAID Architecture towards Fast Recovery and High Reliability

A lot of inexpensive disks in modern storage systems induce frequent disk failures. It takes a long time to recover a failed disk due to its large capacity and limited I/O. This paper proposes a hierarchical architecture of erasure code, OI-RAID. …

Single Disk Failure Recovery for X-Code-Based Parallel Storage Systems

In modern parallel storage systems (e.g., cloud storage and data centers), it is important to provide data availability guarantees against disk (or storage node) failures via redundancy coding schemes. One coding scheme is X-code, which is …
