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,将元数锯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.
針對文件繫統中元數據訪問對應用數據訪問的榦擾問題,基于資源分配分離及訪問路由分髮技術,在藍鯨文件繫統中實現元數據和數據存儲及I/O時的隔離.測試結果錶明,將元數鋸從數據中隔離併將其獨立配置到高速存儲後,應用I/O帶寬提高瞭2.6倍～2.8倍,操作吞吐率提高瞭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 separatl/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.
