1 1 | M. Sutter | IPE | KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) Michael Sutter H.-J. Mathes, K. Daumiller, T. Jejkal, R. Stotzka, A. Kopmann and H. Gemmeke Forschungszentrum Karlsruhe Institute for Data Processing and Electronics (IPE) AugerAccess – Virtual Infrastructure for simulating complex networks

2 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 2 | M. Sutter | IPE | AugerAccess Extension of Pierre Auger Cosmic Ray Observatory EU project in the Sixth Framework Program Improve access to observatory in Argentina –Replication of 7 Tbytes of measured data per year –Upgrade of the communication link Improve management via remote connection –Controllable world wide –Simplify software maintenance –Software for remote control and remote monitoring Authentication and authorization Secure communication

3 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 3 | M. Sutter | IPE | Conditions for Remote Software Problems: –System for Data Acquisition and Slow Control with Hardware distribution on large area Heterogeneous architecture Multiple network services (DNS, DHCP, …) Network boot (PXE – Preboot Execution environment) Complex system architecture –System already in production Not available for development and testing Objectives: –Environment for software development –Additional development system in hardware not possible Virtualization of entire Data Acquisition environment

4 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 4 | M. Sutter | IPE | Auger Observatory Study of ultra-high energy cosmic rays –Energies up to eV –Rare events (one particle per km² and century) Giant detector needed Hybrid measurement –Surface detector (SD) 1600 Water-Cherenkov-Tanks –Fluorescence detector (FD) 24 telescopes in 4 buildings

5 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 5 | M. Sutter | IPE | km² Hardware is distributed

6 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 6 | M. Sutter | IPE | Internet Central campus Radio link 4 buildings 6 computers each

7 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 7 | M. Sutter | IPE | Realization of Virtualization We use IBM Blade –VMware ESX Server as hypervisor on the host –Virtual Infrastructure Client for administration and installation of all virtual machines 2 dual core 2.33 GHz 16 GB Memory

8 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 8 | M. Sutter | IPE | Virtualized development environment Masquerading on Ipecdas Services for Auger software –DNS on Gina and every EyePC –PXE boot for every MirrorPC –DHCP on every EyePC –NFS (Network file system) on every EyePC Auger software Virtual system offers the same capabilities as the observatory in Argentina

9 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 9 | M. Sutter | IPE | Limitations of Virtualization Not possible –Radio link –Special hardware can not be virtualized (telescopes) –Latency time –Hardware characteristics Possible –Simulation of entire FD environment inclusive measurement –Network communication as in the observatory –Easy to copy –Extensible with physical hardware Virtualization fulfills all requirements

10 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 10 | M. Sutter | IPE | Application: Remote Client Service based communication GT 4 Grid security used for authentication and authorization from outside Problems –Auger software in C++, CORBA –GT 4 Java Solution –Apache Axis 2 for coupling of different languages Java Client C Server Problem compiling Axis service with Data Acquisition software

11 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 11 | M. Sutter | IPE | Next steps Installation of remote client Extension with physical hardware –Slow control system for development purposes New version of Operating System –At the moment only one dedicated version is possible Automatic Data Acquisition –Time scheduled from astronomical tables Virtualization of existing observatory –New release configured on development environment –Easy rollback

12 KIT – die Kooperation von Forschungszentrum Karlsruhe GmbH und Universität Karlsruhe (TH) 12 | M. Sutter | IPE | Conclusion Virtualization allows reproduction of entire system –Lower costs –Nearly same possibilities as the hardware Virtualization is flexible solution –Simulating complex hardware architecture –Software development for Auger observatory –Simulation of network architecture –Measurement of data with the development environment Virtualization offers new possibilities for projects in regard to software and architecture development

13 Thank you for your attention!
