摘要
随着高性能计算由传统的主机方式向网络化集群演变,传统的基于主机的存储架构已逐渐向网络化存储发展,计算和存储分离的趋势越来越明显.针对SAN和NAS的不足,国际上已开展针对Linux集群的新型文件系统——对象存储文件系统的研究.以Lustre为例对对象存储的文件分片技术进行了阐述,分析了Lustre的分片机制以及相关的分片技术,实现了一种基于Lustre的文件级RAID机制.实验结果表明,相比于不分片的文件存储机制而言,提高了系统读写性能.
With the high-performance computing from the traditional approach to network-based cluster hosts the evolution of the traditional host-based storage architecture has gradually developed to the network storage.Computing and storage separate trends are becoming evident.SAN and NAS for the inadequacies of the international community has undertaken for the new Linux cluster file system-object store file system.Expatiating file slicing technique by taking Lustre for example,and advances a file slicing method based on Lustre.As a result,it optimizes system capability by improving reading and writing bandwidth of the system.Tests shows that compared with the non-RAID file storage mechanism,file slicing technique can upgrade system capability by advancing throughput efficiency of the system.
