As a network data server, the function of the PowerVault 720N, 740N, or 760N filer is
to move data over the network in response to a client request. The filer uses
Data ONTAP operating system software to do so. The data is stored on storage
disks that reside in PowerVault 700N storage systems connected to the filer. In addi-
tion, a SCSI tape backup device is recommended for regular backups to protect your
data. Therefore, a complete system consists of a filer connected to one or more
PowerVault 700N storage systems, plus an optional (but recommended) tape backup
device.
