Tutorial: High Available OX HE Deployment for up to 100.000 users

This article describes what you need for a typical OX HE Setup for up to 100.000 Users, which is fully clustered and high available.

It contains everything you need to:

  • Understand the design of the OX HE setup including additional services
  • Install the whole system based on the relevant articles
  • Find pointers to the next steps of integration

System Design


The system is designed, to provide maximum functionality and availability with a minimum of necessary hardware. If the services on one server fail, it is enough to take over the IP address to the other machine and service will stay up and running.

Core Components for OX HE

  • Two basic configured Open-Xchange HE servers (HW recommendation: 16GB RAM / 4 cores each)
  • MySQL installed directly on these server
  • NFS Server to store documents and files

Infrastructure Components not delivered by OX

  • An email system providing IMAP and SMTP
  • A control panel for creation and administration of users
  • A Load Balancer in front of the OX servers (optional, recommended)

Overview Installation Steps

To deploy the described OX setup, the following steps need to be done.

Mandatory Steps

  1. Initialize and configure MySQL database on both servers
  2. Install and configure OX on both servers

Steps depending on your environment

  1. Implement Load Balancer
  2. Connect Control Panel
  3. Connect Email System

Recommended Optional Next Steps

  1. Automated Frontend Tests
  2. Upsell Plugin
  3. Mobile Autoconfiguration
  4. Automatic FailOver
  5. Branding

Installation Steps - Instructions & Recommendations

Mandatory Steps

The following steps need to be done in every case to get OX up and running:

Initialize and configure MySQL database on both servers

MySQL will run on both servers. MySQL will be configured as Master-Master configuration to ensure data consistency on both servers. If one machine fails, the other machine will take over all functionality.


Install and configure OX on both servers

OX will be installed on both servers. It will be configured to write to the first MySQL database and to read from the second MySQL database. This will distribute the load during normal operation as smooth as possible.

The NFS server will be mounted and registered as filestore.


Steps depending on your environment

The following components need to be implemented in your environment.

Implement Load Balancer

A load balancer in front of the OX servers is optional, but recommended. (In small environments, DNS Round Robin may be sufficient).

If you do not have a load balancing solution already in place, we recommend to use [[1]] as reliable and cost effective solution.

Connect Control Panel

Connect Email System

Recommended Optional Next Steps

You will find plenty of additional documentation for customization of OX.

When the main setup is completed, we recommend to start with the following articles to enhance your system and to become more attractive for your users.

Automated Frontend Tests

It is a good idea, to verify the functionality of your freshly set up and integrated system. Our QA department does that with tests, running automatically on the web frontend. We release this tests with every release and recommend you to use them to verify your environment with every update.
