基于备份的RAID6在线重构框架
RAID6 ONLINE RECONSTRUCTION FRAMEWORK BASED ON BACKUP
摘要
Abstract
Regarding present problems that the rapid deterioration of reconstruction performance under the continuous heavy workload has never been solved by both the domestics and foreign researches,this thesis proposed for the idea of"accelerating the online reconstruction of RAID 6 by the backup data in external storage".We built the online reconstruction framework of RAID6 based on backup,and completed the prototype system of this framework,and did the corresponding test.The framework utilized the restore bandwidth provided by the backup system to integrate the version data at the latest backup time point into the hot spare disk,and utilized the reconstruction bandwidth provided by RAID 6 to reconstruct the modified data after the latest backup time point to the hot spare disk.It completed the reconstruction process of the disk array RAID6, and restored the disk array RAID6 to normal operation.The test result shows that compared with the existing reconstruction method, the framework greatly improves the reconstruction performance and service performance of RAID6.关键词
