# Quotas
|
|
|
|
|
|
|
|
Storage space is finite and expensive. For this reason, space allocated to each laboratory is limited by a quota.
|
|
|
|
|
|
|
|
There are two types of quotas:
|
|
|
|
|
|
|
|
- **Soft quotas**: these quotas can be exceeded for a short period of time. As soon as the limit is reached, an alert is given by the system and the UDI GIGA-MED IT managers are
|
|
|
|
informed. Users can still write in the group folder, but action should be taken to avoid reaching the hard quota.
|
|
|
|
- **Hard quotas**: As soon as the hard quota of a project is reached, it is impossible to write anything more in the project folder. Similarly, users who would reach their personal
|
|
|
|
hard quota in their home folder will immediately stop being able to write in it. In both cases, the only solution is erasing some data in order to free up space.
|
|
|
|
|
|
|
|
To reduce disk space usage, users should follow the recommendations from the [“Data maintenance” section](mass-storage/mass-storage-management-practices) . If needed, the UDI GIGA-MED IT specialists or the bioinformatics team can help to find ways to further reduce disk space usage.
|
|
|
|
|
|
|
|
If required for a specific project, the PI can contact the UDI GIGA-MED IT specialists to ask for an expansion of the storage space hard quota. This request of more storage space will have to be reasonable and justified.
