一种面向高性能计算的分布式对象存储系统
An HPC-oriented Distributed Object Storage System
摘要
Abstract
The existing distributed file storage system has problems like inefficient data organization and redundant access semantics,etc.,which severely limit the performance of High Performance Computing(HPC)storage system.Therefore,this paper presents HPC-oriented distributed Object Storage System(COSS)based on the idea of object storage.It separates the data access and data management to achieve more streamlined and efficient access semantics,uses distributed global object data organization method and designs memory-based metadata management method to improve system performance.Experimental results show that,under large scale concurrent access,COSS can improve read and write aggregated bandwidth by 22.5％and 50.4％respectively compared with Lustre system.The performance of file creation and file deletion of COSS is respectively 2.15 times and 5.13 times of Lustre system.Meanwhile,COSS provides quasi-linear data read/write performance and metadata management performance.It also has excellent scalability.关键词
