ACL Function

The Access Control List (ACL) function can be used for management of the users with access privileges when
the CIFS and NFS protocols are shared to access shared folders.
ACL can manage access privileges to directories and files as well as the type of granted access for each user
and group.
If ACL is set up for a directory or a file, control is performed regardless of the protocol type (NFS or CIFS) that
is used to access the directory or the file.
5.4 Quota
Quota is a function that limits drive space and the number of files used on a user or group basis.
The drive capacity can be protected from being used exclusively by a specific user or group by setting the
upper limit of the drive space and the number of files available for the user or group. The Quota function
allows the scale of the organization and the use of the system to be taken into consideration to realize flexi-
ble operations.
The Quota settings can be referred to from the target client.
