“…And as we are increasing our use of the resources/services provided by CERN, monitoring of those resources/services is also required. For example, the availability and quota status of AFS [11] and EOS, the status of the usage of LSF and HTCondor, and the activities on CASTOR [12] and FTS3 [13].…”

“…Long-term preservation of the acquired data is granted by staging files into the EOS [8] and CASTOR [9] systems at CERN. The current production of about half a TB of compressed data per data-taking year fits in the minimum experiment quotas on those systems.…”

Abstract. In the sociology of small-to mid-sized (O(100) collaborators) experiments the issue of data collection and storage is sometimes felt as a residual problem for which well-established solutions are known. Still, the DAQ system can be one of the few forces that drive towards the integration of otherwise loosely coupled detector systems. As such it may be hard to complete with off-the-shelf components only.LabVIEW and ROOT are the (only) two software systems that were assumed to be familiar enough to all collaborators of the AEḡIS (AD6) experiment at CERN: working out of the GXML representation of LabVIEW Data types, a semantically equivalent representation as ROOT TTrees was developed for permanent storage and analysis. All data in the experiment is cast into this common format and can be produced and consumed on both systems and transferred over TCP and/or multicast over UDP for immediate sharing over the experiment LAN. We describe the setup that has been able to cater to all run data logging and long term monitoring needs of the AEḡIS experiment so far.

“…There have been several generations of software integrating new technologies like robotic tape handlers and databases as the volume of data exploded ( Fig. 9.2), and evolving to the cluster model with a fully distributed cache [13].…”
