Information on the virtualisation of server systems
The infrastructure department of the HZB IT (IT-IS) offers staff and users the opportunity to use the infrastructure for their own virtualised servers. The hardware - including that on which the virtualised systems reside - is located in the air-conditioned, burglar-proof server rooms at the Adlershof and Wannsee sites. We use VMware to virtualise data centre infrastructure.
The virtual environments for development, test and productive systems are particularly relevant for you as a user.
For your information: development and test servers use relatively fewer hardware resources than production servers. This can lead to slower runtimes and sometimes minimal restrictions in performance.
You can read below how we differentiate between development, test and productive systems.
Development and test environment
Our environment for development and test systems currently comprises a storage space of almost 30TB.
In addition, we operate a DMZ and a standalone cluster.
The so-called Demilitarised Zone contains servers that must be directly accessible from outside the HZB. It currently has a size of 2TB.
For more information on our virtualisation environment for servers, please contact the Infrastructure Department (IT-IS).
Development, test or productive system?
We divide server systems into development, test and productive systems. Therefore, when we provide you with a server, we will want to know what the purpose of the server is.
How do we differentiate between the systems?
- Development server: Development environment. Working version of the application/service running on the server. This will be run locally.
- Test server: Test environment. All errors have been removed from the application/service. Environment is identical to the productive system. Operation is checked in the overall system (databases, peripherals, performance).
- Production server: Production environment on a live server. No more changes are made here.
Before requesting a new system, please consider which of these categories matches your system most closely. You may need more than one server for your work.
Please note that we name the servers using a naming convention based on the division into development, test and production systems.
Virtual PCs at the HZB
If you want to use a virtual system but not a server operating system, we can provide you with a virtual PC. Please see the page Requesting a virtual PC.
For more information on virtual PCs, please see the page Der HZB vPC (only in German).
For technical reasons, we provide virtual PCs on a HyperV environment.
