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。
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.
