RStor Research Storage System
RStor is a mid-performance low-cost storage system launched in 2025 for storing research data that doesn’t have unusual security requirements. RStor is mounted on the Unity batch cluster via NFS and is mountable on UMass Amherst desktop computers via SMB. Shares are managed via the new Unity HPC Platform Allocation Portal. RStor is currently only available to qualified PIs at UMass Amherst.
RStor is hosted at the MGHPCC and undergoes:
- A yearly downtime for a 1-3 days every spring, usually late May or early June
- A monthly maintenance period on the first Tuesday of every month 6-9AM
Data Security
RStor is currently approved for data levels 1 and 2 only, according to UMass Amherst’s Data Categorization Levels.
RStor is not approved for any data subject to restrictions under the Export Administration Regulations (15 CFR Parts 730-774) or the International Traffic in Arms Regulations (22 CFR Parts 120-130), as well as data subject to Health Insurance Portability and Accountability Act (HIPAA) or Controlled Unclassified Information (CUI) safeguarding requirements.
