Overview

The work for the LRZ Data Science Storage (DSS) and DSSWeb Self Service Portal Version 1.4 was dedicated to update the LRZ DSS and HPC infrastructure from IBM Spectrum Scale Version 4 to 5. As a side effect of this, we are now able to provide you self-service management of the NFS exports of your containers. Last but not least, the DSS service is now also available on an on demand basis.

New Features

Service Fullfilment

Besides the joint project offer for procuring and running a complete dedicated DSS building block for your project, we now are also able to offer DSS on demand (DSSOND) for smaller storage requirements starting from 20TB.
