Setting a Quota for a User

Set quota for an individual user.

About this task

You can set quotas for individual users via the Data Fabric UI.

The following quotas can be set.

Advisory quota, which raises an alarm when the threshold is reached, but does not prevent further writes.
Hard quota, which raises an alarm when the limit is reached and prevents further writes.which raises an alarm when the limit is reached and prevents further writes.
Advisory quota and hard quota can be expressed in megabytes (MB), gigabytes (GB), or terabytes (TB). GB is the default unit. The advisory quota must be less than the hard quota.

Follow the steps given below to set quota for a user.

Procedure

Log on to the Data Fabric UI.
Click the Fabric administration icon on the left pane.
Select the fabric name from the Select fabric dropdown.
Click the fabric link for which the user quotas are to be set.
On the Manage Access tab, click the Settings tab.
Select the users option in the dropdown for Quota by.
Click Edit fabric quotas on the Quota by card.
On the Edit Fabric Quotas dialog box, enter the values for user advisory quota, user hard quota, group advisory quota and group hard quota. Change the unit, as required.
Specify the Fabric reserve limit.
Click Update.

Results

The specified quota is saved for the individual user.

NOTE

The default quota specified for the fabric applies to other groups, unless a group-specific quota is set for any other group on the fabric.
