摘要
基于高性能互连实现对象存储系统已经成为构建高性能计算机可扩展I/O系统的发展趋势。我们设计并实现了一种定制的高带宽、低延迟的高性能互连芯片HSNI,它提供了很好的通信性能,可用于构建对象存储系统。本文对HSNI的硬件体系结构、软件结构及其通信机制进行了介绍,并基于HSNI构建了高性能的对象存储系统。性能测试结果表明,HSNI芯片带宽高、延迟低,非常适合构建大规模对象存储系统,该存储系统能够很好地发挥Lustre系统的性能,并具有很好的可扩展性,能够很好地满足面向高性能计算的I/O系统需求。
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.
