Upgrade of the MAGIC data center — •Stefan Rügamer, Thomas Bretz, and Daniela Dorner — Institut für Theoretische Physik und Astrophysik, Universität Würzburg

The data center in Würzburg provides storage capacity and computing power to handle the data of the Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) telescope. On top of this system, a stable and robust analysis is running automatically since two years which processes new data upon arrival or all of the ∼ 37 TB of raw data after a software improvement.

To adapt the data center to the needs of the next generation of experiments, like MAGIC-II or CTA, an upgrade is currently underway. The new system is highly scalable concerning data storage and computing power and will provide up to 1.1 PB of storage capacity when fully upgraded. High data throughput is obtained by using a hierarchical file system as well as taking advantage of the newest tape technologies (LTO4) and a fibre channel online file system. Also the computing performance will be subsequently extended. These resources will also be made available to the German astrophysics community via AstroGrid-D.
