Abstract： |
This invention relates to a graded storing method for mass data characterizing that the customer proxy software of parallel file systems on front hosts realizes support to VFS access by system interface sub-modules and sub-modules of the VFS layer, a metadata server is responsible for organizing data files on different data servers to a unified parallel file system view, and a metadata management module provides operations of accessing metadata, a file migration deciding module gets file access information from the data server periodically and makes decision to file migration according to file system load and grade situation of equipment and an executing module of the data server executes migration. |
