About

**Project Description**: This project aims to benchmark and compare different storage solutions used or considered for CERN's computing infrastructure. The main goal is to evaluate a Pure Storage appliance, HDD/SSD baselines, and CERN's production storage systems, including AFS, CephFS, XRootD and EOS. The benchmarking methodology will rely 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 will 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.

**Supervisor**: Guilherme Amadio, Luca Mascetti
