Data Storage Systems

The HECC environment includes temporary storage systems, home filesystems, and long-term archival storage space for our science and engineering users.

Temporary Storage Filesystems

These filesystems allow users to store their working data prior to transferring it to the archive system for long-term storage. Data is housed on RAID storage to minimize risk. While HECC does not back up the data on these filesystems, users may transfer any data they want to keep to the archive system.

HECC provides Lustre and Network File System (NFS) filesystems to support different I/O usage patterns required by our users.

• Two NFS and twelve Lustre filesystems
• 116.5 PB of RAID storage

Home Filesystems

Each user is provided a home directory on the HECC home filesystems, and data is backed up twice daily.

• 4 HPE Enhanced Network File System (NFS) filesystems
• 24 TB of RAID storage

Archival Storage Systems

For long-term storage, HECC provides an exascale tape storage system that allows users to archive and retrieve important results quickly, reliably, and securely. Data stored on RAID is migrated to tapes as needed. Copies of user data are written to two separate tape media in silos located in two different buildings. HPE's Data Management Framework (DMF) and OpenVault manage data migration (disk-to-tape) and de-migration (tape-to-disk), respectively.

Our storage experts provide custom training to help users efficiently manage their large datasets, as part of the Supercomputing Systems services.
