NAS convergence not only optimizes the utilization of storage space and simplifies such operation as data backup, but also reduces management costs. Based on the research of stackable file system, a method is proposed to implement NAS-Head by inserting stackable file system module between VFS layer and NFS layer, and the system obtains the functions of global storage space, data encryption and data backup. The experiment and analysis show that the NAS convergence system implemented with stackable file system has the following advantages: strong scalability, flexible configuration, simple management and short developing period.
