Quota Management

Overview

The list of quota setting information is displayed.

Quota is a function that limits drive space or the number of files used on a NAS user volume or a shared folder to prevent the depletion of resources in the storage system. There are two types of thresholds ("Warning" and "Limit").

This function is displayed in a Unified Storage environment.

Caution

  • Quotas for NAS user volumes are set for users or groups that are registered in the authentication server. When using this function, registering the users or groups in the authentication server in advance is necessary.

  • Quotas for shared folders are set for shared folders that are registered in the storage system. Create the shared folders in advance. Refer to the [Create Shared Folder] function for details.

Note

  • A unified upgrade is necessary for a storage system that will be used in a Unified Storage environment if it was previously used in a SAN environment. Refer to the [Register Unified Storage License] function and the [Apply Controller Firmware] function for details. This function is added in the category after the unified upgrade is complete.

  • Shared folders include home directories.
