Using Volumes, Shares, and Quotas
• 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. Table 6-2 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.
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.
