Abstract

Storage system has evolved considerably from last four decades. It is a fundamental component of any computerized framework. Therefore, performance of this computerized framework is indirectly proportional to its storage system. In order to improve the performance, decentralized storage system is used to provide high availability without single point of failure. In case of scientific world, execution time of scientific applications are considerably high. Moreover, if the storage system will give slower performance then execution time will also increase to calculate the results. Therefore, it is very important to design efficient storage system to extract better performance of the framework. For decentralized storage system of scientific computing facility, NAS and SAN technologies can be used. In order to design efficient storage system, we have to understand the performance difference between NAS and SAN. In this our experiment, we have created NAS and SAN framework and executed copy command of XRootD framework with different data size. XRootD framework stands above of the NAS and SAN storage system. The experimental results show that the SAN gives better performance than NAS.

面向科学工作流的NAS和SAN存储性能分析

存储系统在过去的四十年中有了很大的发展。它是任何计算机化框架的基本组成部分。因此，这种计算机化框架的性能与其存储系统间接成正比。为了提高性能，采用分散式存储系统来提供高可用性，避免单点故障。在科学领域，科学应用程序的执行时间相当高。此外，如果存储系统提供的性能较慢，那么计算结果的执行时间也会增加。因此，设计高效的存储系统以提取更好的框架性能是非常重要的。对于科学计算设施的分散式存储系统，可以采用NAS和SAN技术。为了设计高效的存储系统，我们必须了解NAS和SAN之间的性能差异。在我们的实验中，我们创建了NAS和SAN框架，并执行了不同数据大小的XRootD框架的复制命令。XRootD框架凌驾于NAS和SAN存储系统之上。实验结果表明，SAN的性能优于NAS。
