# Create a file system user quota on a quota tree

Network-attached storage is a file-level storage architecture that makes stored data more accessible to networked devices.

## About this task

See Understanding PowerMax File for storage systems for an overview of PowerMax File.

A user quota on a quota tree limits the amount of storage that an individual user consumes when storing data on the quota tree.

## Steps

1. Select a storage system that supports PowerMax File.
2. Select Storage > File.
3. Select the FILE SYSTEMS tab.
4. Click VIEW ALL DETAILS.
5. Select the TREE QUOTAS tab.
6. Click and select Create User Quota.
7. Select the host type.
8. Configure the storage limits.

   A hard limit is an absolute limit on storage usage. If a hard limit is reached for a user quota on a file system or quota tree, the user cannot write data to the file system or tree until more space becomes available. If a hard limit is reached for a quota tree, no user can write data to the tree until more space becomes available.

   A soft limit is a preferred limit on storage usage. The user is allowed to use space until a grace period has been reached. The user is alerted when the soft limit is reached, until the grace period is over. After that, an out of space condition is reached until the user gets back under the soft limit.

9. Click OK.
