The server running PostgreSQL should have _at least_ 5-10 GB of storage
available, though the exact requirements [depend on the number of users](../administration/reference_architectures/index.md). For Ultimate customers the server should have _at least_ 12 GB of storage available, as 1 GB of vulnerability data needs to be imported.

We highly recommend using at least the minimum PostgreSQL versions (as specified in
the following table) as these were used for development and testing:
- Most GitLab self-managed instances, at least 5 to 10 GB of storage available.
- GitLab self-managed instance at the Ultimate tier, at least 12 GB of storage available, because 1 GB of vulnerability
data must be imported.
You should use the versions of PostgreSQL specified in the following table for your version of GitLab because these were
used for development and testing:
| GitLab version | Minimum PostgreSQL version<sup>1</sup> | Maximum PostgreSQL version<sup>2</sup> |
