Gitlab and JIRA integration

It is possible integrate GitLAB with JIRA in server level, or integration is possible only in project level?

@itinfo We currently have two different types of integrations with JIRA. The first here is mainly for integrating your issues on JIRA with GitLab issues and is available in Community Edition. The second, documented here is a bit more extensive and you’ll need to be an Enterprise Edition subscriber to access it.

Hi! Can you explain me about first integration with Jira, I can change JIra issue status only to closed/fixed? Or I can changed to all workflow status.
Ready for test
by commit which looking as: Tested JIRAISSUE-1
and etc?
If it’s not possible, maybe you give me advice how I can do it or in’s unreal?
