50 TB | 2000k | Yes 500TB |

50 GB | 100k | Yes 500GB |
No | Project lifetime |
| Project Fast |
2 TB | 1000k | Yes 100TB |

When a storage space is marked as expandable, it means that you can request more space if needed.
LUMI-F unavailable until summer 2022
To prepare for the installation of LUMI-G, LUMI-F has been removed from the system and will be available again after LUMI-G installation is completed.
Data rentention policies not active
Scratch automatic cleaning is not active at the moment. Please remove the files that are no longer needed by your project on a regular basis if you don't want to run out of TB-hours.
Billing
Storage is billed by volume as well as time. The billing units are TB-hours. For the regular scratch file system, 1TB that stays for 1 hour on the filesystem, consumes 1TB-hour. For the flash based filesytem 1TB for 1 hour consumes 10 TB-hours.
User Home
Each user has a home directory ($HOME) that can contain up to 20 GB of data.
It is intended to store user configuration files and personal data. You are
NOT supposed to run jobs from your home directory.
The user home directory is purged once the user account expire.
Project Persistent Storage
The Project Persistent storage is intended to share data amongst the members of a project. You can see this workspace as the project home directory. Typically, this space can be used to share applications and libraries compiled for the project. Just like the user home directory you are NOT supposed to run jobs from your the project persistent space.
The project persistent storage is located at /project/project_<project-number>.
The project persistent directory is purged once the project expire.
Parallel Filesystems (Scratch)
LUMI-F unavailable until summer 2022
To prepare for the installation of LUMI-G, LUMI-F has been removed from the system and will be available again after LUMI-G installation is completed.
The scratch spaces are Lustre file systems intended as temporary storage for input, output or checkpoint data of your application. LUMI offers 2 types of scratch storage solution: LUMI-P with spinning disks and LUMI-F based on flash storage.
