In order to improve the system bandwidth and storage capacity of the storage system

designing a stackable disk storage array model

and the controller and the disk array management module was implemented in the FPGA; To solve the problem of metadata and data

designing cache and multi-channel read and write control mechanism

processing module with a logic unit address mapping to the q channel

and SATA control module data mapping to channel P on the disk

realizing the parallel read and write access of the data. The experimental results show that the stackable storage array is efficient and flexible

and can greatly improve the storage capacity and bandwidth

and has great application value.
