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)/li>
  • 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)
