LZR - the Lehmann Center Data Center

LZR is the first construction phase for the planned Lehmann Center of the TU Dresden, a crystallization point that will provide a "roof" for the Center for Interdisciplinary Digital Sciences (CIDS) and unite the ICT-oriented research, development and also service of the TU Dresden in the areas of hardware and software. The LZR was put into operation with the installation of the high-performance computer/storage complex (HRSK-II) in May 2015. Designed for up to 5 MW of electrical power, the data center houses the central IT systems of the TU Dresden in addition to the supercomputers on more than 1200 square meters of computer room space.

The LZR provides important IT services not only for TU Dresden, but also for many other Saxon research institutions, such as the University Hospital Dresden (UKD), the Max Planck Institute for Molecular Cell Biology and Genetics (MPI-CBG) and the Saxon State Library - Dresden State and University Library (SLUB). The basis is always a fast and geo-redundant data connection - for example to the Johannstadt campus with over 100 GBit/s.

Electrical Power

A reliable power supply is ensured at the LZR by redundant medium-voltage feed and several UPS systems including a backup power system (emergency diesel). IT systems are categorized according to availability requirements, and all important and critical services are supplied via two physically separate, fully redundant power supply paths. Annual black building tests are conducted to verify the correct functioning of this critical infrastructure from the feed to the consumer.

The cooling supply is also optimized for high availability and efficiency. Three completely separate cooling circuits at different temperature levels ensure that all IT systems are cooled efficiently and in line with requirements. The higher the water temperature, the higher the proportion of energy-saving free cooling. Our high-performance computers feature year-round hot water free cooling. Redundant system design ensures the required high availability.

Waste heat utilization

The warmest chilled water circuit of the LZR is operated with a supply temperature of about 35°C. The heat is decoupled and fed into a local heating network. This is used, for example, to supply heat to the Hermann Krone Building (KRO), where large quantities of conditioned air (temperature, humidity) have to be provided all year round for clean rooms.
