ABSTRACT:
A data storage system includes file system processes, array controller processes, and one or more data storage devices accessed through the array controller processes. Certain file system access operations are diverted from the file system processes so that the array controller processes can directly perform the requested access operation. The array controller processes then communicate with the file system processes so that the file system processes may update the file system data management arrangement as appropriate. Thus, the hierarchical file system management is maintained while the storage media may be accessed through one of multiple routes in response to a file system access operation request. The particular access route for a given file in the system is determined by a route determinant characteristic of the file. The access route for a file may be switched when it is determined that the route determinant characteristic for the file is inconsistent with the then specified route for that file.
