蓝鲸文件系统中元数据与数据隔离技术
IsolatI/On Technology of Metadata from Data in Blue Whale File System
【摘要】 针对文件系统中元数据访问对应用数据访问的干扰问题,基于资源分配分离及访问路由分发技术,在蓝鲸文件系统中实现元数据和数据存储及I/O时的隔离。测试结果表明,将元数据从数据中隔离并将其独立配置到高速存储后,应用I/O带宽提高了2.6倍~2.8倍,操作吞吐率提高了2倍~5倍。
【Abstract】 Aiming at the performance interference between metadata and data access,this paper proposes a novel mechanism in Blue Whale File System(BWFS) to isolate metadata from data both in physical storage and I/O path. The isolatI/On is realized by the resource separatI/On and I/O request dispatching. Test results show that,after metadata is separated and put in the high-performance media,the applicatI/On I/O bandwidth is increased by 2.6 times~2.8 times,while OPS is improved by 2 times~5 times.
