Performance, reliability and scalability in data access are key issues in the context of HEP data processing and analysis applications. In this paper we present the results of a large scale performance measurement performed at the INFN-CNAF Tier-1, employing some storage solutions presently available for HEP computing, namely CASTOR, GPFS, Scalla/Xrootd and dCache. The storage infrastructure was based on Fibre Channel systems organized in a Storage Area Network, providing 260 TB of total disk space, and 24 disk servers connected to the computing farm (280 worker nodes) via Gigabit LAN. We also describe the deployment of a StoRM SRM instance at CNAF, configured to manage a GPFS file system, presenting and discussing its performances.

Abstract

Performance, reliability and scalability in data access are key issues in the context of HEP data processing and analysis applications. In this paper we present the results of a large scale performance measurement performed at the INFN-CNAF Tier-1, employing some storage solutions presently available for HEP computing, namely CASTOR, GPFS, Scalla/Xrootd and dCache. The storage infrastructure was based on Fibre Channel systems organized in a Storage Area Network, providing 260 TB of total disk space, and 24 disk servers connected to the computing farm (280 worker nodes) via Gigabit LAN. We also describe the deployment of a StoRM SRM instance at CNAF, configured to manage a GPFS file system, presenting and discussing its performances.
