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.展开更多
