**Iridium Cluster**

To be scheduled.


==== Selection criterias ====

Machines with unsupported operating systems should be upgraded. However:
  - For Workstations/Remote Workstations with memory less than or equal to 2GB, the target upgrade will be Lubuntu 12.04 (Supported until Apr, 2017 see https://wiki.ubuntu.com/Releases)
  - For Workstations/Remote Workstations with memory above 2GB, the target upgrade will be Ubuntu 14.04 (Supported until Apr, 2019 see https://wiki.ubuntu.com/Releases)
  - For Servers, the target upgrade will be CentOS 6.5 (Supported until November 30th, 2020 see http://wiki.centos.org/About/Product#fndef-f629e99f98d098d5979628e3a302a1b0579202ce-1)

==== Situation ====

OpenSuSE dropped or will drop support for most of the OS versions we have. As a result the machines are
at security risk and most of the libraries will stay obsoleted and without bugfixes. Sources:
  * https://en.opensuse.org/Lifetime
  * https://en.opensuse.org/Evergreen

Planned Upgrade is either to Lubuntu 12.04 or Ubuntu 14.04 for Workstations/Remote Workstations or Centos 6.5 for Servers.
