基于Ceph文件系统的元数据缓存备份
Metadata Cache Backup Based on Ceph File System
摘要
Abstract
In order to solve the problem of long response time of metadata writing in Ceph file system,a metadata cache backup scheme is proposed.The scheme backups the metadata among multiple servers to guarantee the reliability of the metadata,and multi-queue cache organization structure based on the heat of the metadata and the relevant cache prefetching and destage algorithms are designed.Compared with the performance of the Ceph metadata management subsystem,experiment results show that the performance of the proposed scheme is improved by 15.7%.关键词
