ACAWM:一种NAS高性能协作写缓存机制

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.

The NAS can satisfy the requirement of more big capacity, more faster access speed and more easier access for the storage system. The conventional NAS usually lacks the cooperation mechanism and can not utilize the resource of other NAS to get high performance.
