Abstract The serial communication has the advantages of faster transformation speed, less interference and interface complexity, et, al, so it is widely used in cloud storage system. Cloud storage applies the network technology to manage the storage devices to work together and it will be the development trend of storage technology. The paper introduces the principle of a serial communication protocol for cloud storage system. In order to realize the system, we use USB protocol as an example to analyze the physical layer communication protocol for cloud storage system. The design is described in VHDL language, simulated with ISE Simulator and then verified on FPGA of Xilinx Virtex series.
