Context

CERN operates the Large Hadron Collider — the world’s largest particle accelerator — where enormous volumes of scientific data are generated every second. To sustain a continuous process of scientific discovery, the organization needs an infrastructure that combines high compute density, scalable storage, and sustainable design.

The Challenge

CERN’s scientific environment requires infrastructure that runs reliably under constant workloads and massive datasets. Key requirements include:

• continuous operation with no compromise on stability;
• high-speed access to storage resources;
• efficient data management and protection;
• optimized energy consumption;
• readiness for future scientific experiments.

Persy’s Engineering Approach

Following an international procedure, CERN selected Persy as a supplier of server and storage systems. The architecture combines high-density server platforms and scalable storage design optimized for scientific computing.

• high-performance server systems for scientific workloads;
• petabyte-scale storage infrastructure;
• data optimization and protection technologies;
• sustainable design aligned with energy-efficiency goals.
