ACAWM：一种NAS高性能协作写缓存机制

1.引言随着计算机技术的不断发展,对更大数据存储容量和更快信息访问速度的要求也越来越高。为了满足这样的需求,一种新型数据存储技术——附网存储(NAS,Net AttachedStorage)出现了。NAS是一种不依赖于平台的高性能数据存储技术,它使用专门优化的硬件和软件来提供高性能的文件服务。NAS的优点在于:①不依赖于平台的多协议数据存储

ACAWM :A High Performance Write Cache Manage Mechanism for NAS

The NAS can satisfy the requirement of more big capacity,more faster access speed and more easier accessfor the storage system. The conventional NAS usually lacks the cooperation mechanism and can not utilize the re-source of other NAS to get high performance. This paper presents a high performance cooperation write cache mecha-nismfor NAS-ACAWM. ACAWM introducs the automatic cooperation mechanism and asynchronous write mecha-nism into NAS. Automatic combination methanism can make NAS to cooperate each other without artificial configura-tion and asynchronous write mechanism improves the performancc of the file write. The design of ACAWM fully con-siders over the usability of NAS and has no special requirement of the client. At last,this paper uses experiment toprove that ACAWM can greatly improve the performance of NAS.
