Storage

The total storage space available is 12 PB.

Data may be located either on our NFS servers or on fast storage, our 11.5 PB BeeGFS distributed file system (fast storage).

Home folders are located on NFS storage by default. Project folders are located on fast storage. Fast storage is reserved for large data files involved in I/O intensive computations.

NFS can deliver read/write performance of up to 700MB/s, while fast storage can reach an aggregated read/write performance of more than 35GB/s.

Backup

Backup is made to AU ITs IBM-TSM disk and tape archive.

Power

Storage and switches are protected by 3x40 kVA UPS. Diesel generator provides long term power backup for storage and switches.

In case of power failure, only frontend and compute nodes will be without power.
