 # Storage Management and Quotas
 
 
-The servers have quite different storage capabilities and settings. 
+The servers have quite different storage capabilities and settings. However, all servers have quotas activated to limit the disk occupation of single users. If you don't know what different types of quota mean, please check [online](https://en.wikipedia.org/wiki/Disk_quota).
+
+Users can check their quota limits and current occupied space usage with the following command:
+
+```
+quota -s
+```
+
+Group quotas (currently not used) are checked with:
+
+```
+quota -s -g
+```
+
+The minimum between the user and group quotas is what determines the available space for a user.
