IsolatI/On Technology of Metadata from Data in Blue Whale File System
Lu Xiong Xu · Jisuanji gongcheng · 2010
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.
