CRAY XC40 Disk Storage
Users' HOME directories are located on a shared RAID system and are mounted via NFS on all login (frontend) and compute nodes. The path to the HOME directories is consistent across all nodes. The filesystem space on HOME is limited by a small quota!
For large files and fast I/O Lustre based scratch directories are available which make use of the high speed network infrastructure (Aries). Scratch directories are available on all compute and login (frontend) nodes via the workspace mechanism.
The available storage capacity is about 5.4PB
IMPORTANT! NO BACKUP!! There is NO backup done of any user data located on HWW Cluster systems. The only protection of your data is the redundant disk subsystem. This RAID system is able to handle a failure of one component. There is NO way to recover inadvertently removed data. Users have to backup critical data on their local site!
Long term storage
For data which should be available longer than the workspace time limit allowed and for very important data storage, please use the High Performance Storage System HPSS
