对于典型的基础设施即服务（IaaS）云使用情况，为了强化一个系统，需要临时且频繁地配置虚拟卷。然而，硬盘驱动器（HDD）存储的性能并不足够，并且现已成为IaaS云的一个瓶颈。在本文中，我们对硬盘 - 固态硬盘（HDD - SSD）混合存储、分布式存储以及普通硬盘存储作为OpenStack Cinder的块存储进行了比较研究，并评估了这三种存储类型对IaaS云的适用性。与硬盘存储相比，混合存储能够实现高得多的性能，并且适用于分析应用；而当并发处理数量增加时，分布式存储的性能下降幅度低于硬盘存储，并且适用于归档或存储大量文件。© 2016日本电气工程师学会。由约翰威立父子公司出版。
For a typical IaaS (infrastructure as a service) cloud usage, to strengthen a system, temporary and frequent provisioning of virtual volumes is needed. However, the performance of HDD (hard disk drive) storage is not sufficient and has become a bottleneck in IaaS cloud now. In this letter, we make a comparative study of HDD–SSD (solid‐state drive) hybrid storage, distributed storage, and normal HDD storage as the block storage of OpenStack Cinder, and evaluate the applicability of these three types storage to the IaaS cloud. Hybrid storage can achieve much higher performance compared to HDD storage and is suitable for analysis applications, but distributed storage performance degradation is lower than HDD storage when the number of concurrent processing is increased and is suitable for archiving or storing a large number of files. © 2016 Institute of Electrical Engineers of Japan.
