Hardware Requirements

General Assumptions

Open-Xchange App Suite Server (middleware services) is designed to run on physical servers or virtual machines of the same flavor. Cloud environments might be used in terms of Infrastructure as a Service (IaaS), meaning that all components need to be deployed in a classical manner on virtual machines.

This means in particular, but not only:

  • Infrastructure is "quasi-static". We don't need to take into account things like VMs coming and going dynamically, dynamic IPs, volatile ("ephemeral") data
  • "Database as a service" is not allowed. This typically is a highly customized "MySQL like" storage engine, and not a true MySQL, and we can't control flavor, version, setup, etc. If need for configuration changes is identified, we won't be able to change anything.

So to summarize: we expect any virtualized platform to behave and work just like a well-known non-virtualized / physical platform.

Especially we expect the virtual hardware to be not over-provisioned. Each VM must have dedicated resources with respect to CPU cores, RAM, IOPS, storage, network bandwidth, network latency, etc.

Network is expected to be flat, inside one datacenter, no multi-datacenter, no segments. No packet loss, low latency.

Disclaimer: All recommendations below are without guarantee and can differ for specific deployments. For mid- and large-scale setups a detailed deployment planning and sizing tests are mandatory and should be agreed on with OX Professional Services.

High Level Design / OS setup

Operate services separately (USM, Document/Image Converters) as described in Cluster Setup.

Clocks between all nodes must be synchronized (e.g. via NTP).

Open file/max process limits need to be adjusted properly. Based on the used Linux distribution and init system configuration will differ, see Resource Limits for further explanation.

Platform Architecture: 64 bit versions (x84_64) of the supported Linux distributions

Node Sizing

  • Max. 8 GB heap per JVM + 4 GB system memory for other daemons and the OS (buffers, caches)
  • 4 CPU cores (virtual, physical or hyperthreads)
  • Disk space
    • 5 GB for OS and software
    • 2 * system memory of free disk space (i.e. 12 GB RAM => 24 GB free disk space) for file spooling, log files, heap and core dumps

Untested/Unsupported Deployments

  • Changes to Garbage Collector settings
  • Running in containerized environments (Docker, rkt)
  • Elasticity/High velocity of nodes going up and down: Services are sometimes stateful and demand static configuration
  • Cloud platform services (PaaS) like database systems (for example AWS RDS)
  • Multi-site active-active

Software Requirements

Linux Distributions

OX App Suite is available as Linux packages for the following distributions:

Distribution Versions Derivates
     
Suse Linux Enterprise Server 12 None
Red Hat Enterprise Linux 6,7 CentOS
Debian 8 (Jessie), 9 (stretch) None

Java

OX App Suite Middleware requires OpenJDK headless JRE 8 or 9.

Please note: For Debian 8 (Jessie) OpenJDK 8 is only available via the jessie-backports repository.

Databases

OX App Suite uses MySQL with the InnoDB storage engine as its primary data store. The following vendors and products are supported.

Vendor Product Versions
     
Oracle MySQL Community Edition, Standard Edition, Enterprise Edition [5.6.x, 5.7.x]
MariaDB MariaDB Server, Galera Cluster [10.1.x, 10.2.x]
Percona XtraDB Cluster [5.6.x, 5.7.x]

Important Notes

  • For some Linux distributions the included MySQL/MariaDB packages are too old to be used with App Suite. It is mandatory then to install a supported version from upstream package sources. Possible sources are the official vendor repositories of MySQL, MariaDB or Percona as well as for example Red Hat Software Collections.
  • Required MySQL configuration differs between App Suite 7.8.4 and 7.10.0 and also between the different database systems in terms of SQL modes. See My.cnf for details.
  • For upgrades to App Suite 7.10.0 a comprehensive database upgrade guide exists: AppSuite:7_10_Database_Migration

File Storage

Temporary Data

OX App Suite stores temporary files in the local file system, e.g. for spooling of uploaded data. Any file system supported by the installed JRE is suitable.

Persistent Data

Persistent data like OX Drive files, PIM attachments etc. needs to be stored in a distributed file system that is available from all server nodes. For single-node setups a local file system mount point can be used, small to mid-scale setups can be powered by NFS. For large-scale setups object storages should be considered.

Object Storages

OX App Suite ships with different optional adapters to support object storages.
