Abstract: I/O performance of large-scale HPC systems grows at a significantly slower rate than compute performance. In this article we investigate architectural options and technologies for a tiered storage system to mitigate this problem. Using GPFS and flash memory cards a prototype is implemented and evaluated. We compare performance numbers obtained by running synthetic benchmarks on a petascale BlueGene/Q system connected to our prototype. Based on these results an assessment of the architecture and technology is performed.
