The number of file systems does not include the number of NAS backup volumes.
System volumes are required in the ETERNUS DX to control the NAS system. In addition, system management
area is required for each file system.
After creating a shared folder in the file system, accessing the shared folder from the client becomes available,
and directories and files can be stored in it. Access control can be set for each shared folder, directory, and file.
