You can also choose to store session data in a Redis/Memcache/Postgres/MySQL which means that the load balancer can send a user to any Grafana server without having to log in on each server. This requires a little bit more work from the operator but enables you to remove/add grafana servers without impacting the user experience.

If you use MySQL/Postgres for session storage, you first need a table to store the session data in. More details about that in [[sessions]]({{<relref"../installation/configuration.md">}}#session)

For Grafana itself it doesn't really matter if you store the session data on disk or database/redis/memcache. But we recommend using a database/redis/memcache since it makes it easier manage the grafana servers.
