Storage

The total storage space available is 3.5 PB.

Data may be located either on PANASAS 110TB SAN storage (panfs), on one of eight EONSTOR SANs (nfs) or on our 3 PB BeeGFS distributed file system (fast storage).

Home and project folders are located on panfs and nfs storage by default. The fast storage is reserved for large data files involved in I/O intensive computations.

Panfs and nfs can deliver read/write performance of up to 700MB/s, while the fast storage can reach an aggregated read/write performance of more than 35GB/s. Fast storage is a 32 node distributed file system running BeeGFS+a self-developed disaster-recovery add-on. 

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.
