摘　　要：参考服务器/客户端的可堆叠通信模式,以最常见的SATA硬盘作为存储介质,Marvell 88SM9705为核心控制芯片,设计了一种可堆叠的存储介质。经测试,88SM9705通过解析主机端发送来的SATA 3.0协议定义的帧信息结构(Frame Information Structure,FIS)中PM Port地址字段,能依次对其所连接的多个SATA硬盘进行正确的读、写等操作,实现了存储设备的可堆叠,稳定性能良好。是一种实现扩容同步提速的可堆叠存储阵列解决方案,在嵌入式存储系统领域具有很好的应用前景。Referring to the communication model of server and client,the paper designs astackable storage medium using the88SM9705chip of Marvell with the general SATA hard disks asthe storage medium.The test results indicate that88SM9705chip could recognize the PM Port addressfield of Frame Information Structure(FIS)defined in the SATA3.0protocol,and read and write SATAhard disks connected with the chip.Completing the stackable storage device,and it has good stability,which is a solution of capacity expansion with speed increase to the stackable storage array.There is abetter application prospect of embedded storage systems filed.
