• Quotas - Quotas are also defined per NAS volume. Different quota policies can be applied to different NAS volumes, allowing the administrator to focus on managing quotas when it is appropriate. Some of the usage examples are copy operations, list operations, and move operations. The following table provides an example of an organization that has various departments and how NAS volumes can be created. The right solution depends on the customer's requirements because NAS volumes are flexible and they can be expanded and reduced on demand. Table 1.

In this scenario, the departmental requirements are quite different and supports the design to logically create NAS volumes along department lines.

The disadvantage of this option is that the NAS volumes become difficult to manage if the number of departments in the organization increases. Solution 2 Group departments that have similar security requirements into NAS volumes. The administrator creates three NAS volumes, one for NFS, one for CIFS, and another for mixed. The advantage is that the NAS volumes work separately between Windows and Linux. This solution has the following disadvantages: • All files in a NAS volume are backed up. • Unwanted services may be provided to certain departments. If a CIFS volume is created to backup data for the administration and finance departments, the press and legal departments also get backups even though they do not require it. 26

Solution 1
Create five NAS volumes based on the departments. The administrator logically breaks up the storage and the
management into functional groups. In this scenario, the departmental requirements are quite different and supports the
design to logically create NAS volumes along department lines.
This solution provides the following advantages:
•
It is logically easy to manage the NAS volumes.
•
The NAS volumes are created to match the exact needs of the department.
The disadvantage of this option is that the NAS volumes become difficult to manage if the number of departments in the
organization increases.
Solution 2
Group departments that have similar security requirements into NAS volumes. The administrator creates three NAS
volumes, one for NFS, one for CIFS, and another for mixed. The advantage is that the NAS volumes work separately
between Windows and Linux. This solution has the following disadvantages:
•
All files in a NAS volume are backed up.
•
Unwanted services may be provided to certain departments. If a CIFS volume is created to backup data for the
administration and finance departments, the press and legal departments also get backups even though they do
not require it.
