The information technology center (HRZ - Hochschulrechenzentrum) provides the departments in the HRZ data center with their own server racks. This means that important computing technology in the departments with higher requirements in terms of cooling, network connection, uninterruptible power supply and access security can be supplied and operated. The servers remain organizationally and administratively completely in the hands of the departments. They also manage and allocate the spaces in their racks themselves.
