HPC PERUN Storage System¶
Overview¶
| The HPC PERUN storage system is a high-performance, scalable, and resilient data infrastructure designed for processing, storing, and long-term archiving of scientific data. It supports the full data lifecycle — from real-time high-speed computation to secure long-term preservation of research outcomes. Its architecture consists of three functional storage tiers, each optimized for specific types of workloads and user requirements. Together, they form a unified environment that ensures maximum speed, reliability, and durability for scientific and industrial research. |

Storage Architecture¶
The PERUN storage infrastructure is divided into three specialized tiers, each serving a unique purpose depending on user workloads and performance requirements.
1. Scratch Storage (High-Speed Working Tier)¶
A temporary, ultra-fast workspace intended for short-term data generated during active computational workloads.
Configuration: - 1 × SMU server HPE E2000 - 1 × MDU HPE E2000 - 6 × SSU-F HPE E2000 (2U32)
Technologies: Lustre, gridRAID
Capacity: ~730 TB (excluding gridRAID redundancy)
Connectivity: 400 Gbit InfiniBand
This tier is optimized for maximum throughput and massively parallel access, enabling efficient processing of large-scale simulations and computing tasks.
2. Performance User Tier¶
A fast, reliable workspace for active data processing, development work, and daily operational tasks.
Configuration: - 2 × NetApp AFF C60
Capacity: 189 TB (excluding RAID)
RAID Level: RAID-DP
Connectivity: 8 × 100 Gbit
This tier ensures high responsiveness for common user workflows and mid-term project data management.
3. Capacity Archival Tier¶
A long-term, secure storage environment for large datasets, research results, and archival workloads.
Configuration: - 6 × NetApp AFF A90 - 1 × NetApp FAS 70
Capacity: ≈ 5 PB
RAID Levels: RAID-DP, RAID-TEC
Connectivity: 14 × 4 × 200 Gbit
This tier is designed for maximum reliability, availability, and data protection, ensuring safe long-term storage of critical research outputs.
