Description
This CERN Openlab Summer Student project aimed to benchmark and compare different storage solutions used or considered for CERN's computing infrastructure. The main goal was to evaluate a Pure Storage appliance, HDD/SSD baselines, and CERN's production storage systems, including CephFS, XRootD and EOS. The benchmarking methodology relied on Flexible I/O (FIO) scripts designed to reasonably reproduce realistic High Energy Physics (HEP) analysis patterns and common user activities. The results of this study provide a comprehensive performance characterisation of the investigated storage solutions, helping to identify suitable candidates for the next deployments and improvements to CERN's computing services.
