The Interdisciplinary Centre for Mathematical and Computational Modelling (ICM) was founded in 1993 at the University of Warsaw, Poland. Their challenges are to optimize data storage capabilities in a highly heterogeneous HPC (High-Performance Computing) environment and the solution should meet growth, performance and space efficiency requirements. They chose NetApp to overcome these challenges. They have deployed a high-performance, high-density NetApp E5460 solution to accommodate short-term and long-term data from a range of computation applications. The results of implementing NetApp were outperforming performance requirement of at least 6GB/sec, achieved a data center footprint of only 56U for 2.1PB of storage, delivered on-time compute and storage services to computation applications, including the regularly updated weather forecast and added to ICM's reputation as a leading HPC center.
