Abstract:

The trend as such makes it very promising to build a scalable I/O system for highperformance computing through the implementation of an objectbased storage system based on highperformance interconnects. We design and implement a custombuilt highperformance, low latency interconnects chip HSNI, which provides a  very good performance of communication, and can be used to build objectbased storage systems. Firstly, we introduce the hardware architecture, the software structure and the communication mechanism of HSNI. Then we implement an objectbased storage system based on HSNI. The experimental results show HSNI can provide high bandwidth, low latency data transfer, and is very suitable for building objectbased storage systems, and the storage systems based on HSNI can exert the performance of Lustre effectively with good scalability, which satisfies the demands of the I/O system for highperformance computing perfectly.
