openQRM Enterprise Edition Comparison

Edition Comparison
A functionality/ plug-in comparison of the different openQRM Enterprise editions.

If you are building professional datacenter and cloud computing platforms, you need reliable support options or comprehensive features. This Comparison gives you an overview of the differences between the openQRM Enterprise Editions.

openQRM Editions:

  • Free Community Edition
  • Docker Collaboration Server Edition
  • KVM Edition
  • ISP Edition
  • PrivateCloud Edition
  • VMware vSphere Edition
  • Enterprise Edition

openQRM Enterprise has a Server-Client license model. All openQRM Enterprise Editions include 1 openQRM Server license and 2 Client/ Host licenses for physical machines managed by openQRM (No license renewal necessary). Additional, renewable Client/ Host licenses are available for managing small, medium or large set-ups with hundreds of Clients/ Hosts.

openQRM System Requirements

Requirements for the openQRM Server
openQRM is lean and has very low system requirements, leaving you more system capacity for operations.
Minimum hardware setup:
  • virtual or physical system
  • 1 GB RAM
  • 100+ GB free hard disk space
  • 1 network interface card (1 GBit/s)
  • openQRM Enterprise Cloud

Recommended hardware setup:
  • physical system
  • 4 GB RAM
  • 100+ GB free hard disk space
  • 1 network interface card (1 GBit/s or faster) for every management network to connect to

Supported Client operating systems:
  • Linux (Debian, Ubuntu, RHEL, CentOS, OpenSuSE)
  • Windows (XP, Win7, Win8, Windows 2kX Server - 32/64bit)
  • Solaris
  • FreeBSD

Browser Requirements to use the openQRM web interface

Any fairly modern browser will do:

  • Firefox, Google Chrome, Safari, Internet Explorer
  • Cookies must be enabled
  • Javascript needs to be enabled for full functionality
  • basic functionality available for simple text-mode browsers (lynx, w3m, etc.)

Works in mobile browsers on these platforms:

  • iOS Safari (iPod, iPad, iPhone)
  • Android
  • Windows Phone

Simple proof-of-concept setup (1 machine)
  • 1 physical system dedicated to the openQRM server
  • Intel or AMD 64bit dual/quad core CPU
  • VT CPU extension (full virtualization support) activated
  • 1 GB RAM (the more the better)
  • a free harddisk/partition dedicated to the server-image store (at least 20 GB)
  • 1 network interface card (1 Gbit/s)
  • internet access to download required software
  • basic functionality available for simple text-mode browsers (lynx, w3m, etc.)

For an evaluation setup all components such as storage, virtualization and openQRM itself can be installed on a single system. For a production setup it is recommended to use dedicated systems for each component.


Minimal production setup

3 physical systems

  • openQRM Server
  • storage host
  • virtualization host

Virtualization host

  • VT CPU extension (full virtualization support) active
  • at least 8 GB of RAM (the more the better)
  • 2 NICs (one to management/storage network, one to the internet/cloud service LAN)

Storage host

  • free partition dedicated to the server-image store (at least 100 GB) on the storage host
  • 1 or more NICs (1GBit/s or faster) to connect to the management/storage network

openQRM server: 4 GB RAM

The basic setup distributes the storage and virtualization services to external servers and provides better performance and scalability.

Recommended production setup

6+N physical systems

  • two for openQRM server HA
  • 2+N storage
  • 2+N virtualization hosts

Virtualization hosts

  • VT CPU extension (full virtualization support) on the virtualization host
  • at least 8 GB of RAM (the more the better)
  • 4 NICs (2x management/storage network, 2x internet/cloud network)

Storage host

  • lots of hard disk space (SAN or HA shared storage system recommended)
  • 4 or more NICs (1GBit/s or faster) to redundantly connect to the management/storage network (bonding)

openQRM servers

  • 8 GB RAM
  • 2 NICs (1GBit/s or faster), redundantly connected to the management network (2 switches)
