+## Enable Pages network storage in multi-node environments
+
+Object storage is the preferred configuration for most environments. However,
+if your requirements call for network storage and you want to configure Pages
+to run on a [separate server](#running-gitlab-pages-on-a-separate-server), you should:
+
+1. Ensure the shared storage volume you intend to use is already mounted and
+   available on both the primary server and your intended Pages server.
+1. Update the `/etc/gitlab/gitlab.rb` of each node to include:
+
+   ```ruby
+   gitlab_pages['enable_disk'] = true
+   gitlab_rails['pages_path'] = "/var/opt/gitlab/gitlab-rails/shared/pages" # Path to your network storage
+   ```
+
+1. Switch over Pages to your separate server.
+
+After you successfully configure Pages on your separate server, only that server
+needs access to the shared storage volume. Consider keeping the shared storage volume
+mounted on your primary server, in case you must migrate back to a single-node environment.
